CVSS v3.1 |
| XenForo before 2.3.13 contains an uncontrolled recursion vulnerability in the BBCode parser that allows authenticated attackers to cause persistent denial of service by submitting a post with deeply nested BBCode tags. Attackers can craft a single malicious post with sufficient nesting depth to exceed PHP's stack limit, causing fatal errors that repeatedly terminate PHP-FPM workers for all visitors rendering the affected thread. |
| XenForo before 2.3.13 contains an unauthenticated information disclosure vulnerability that allows unauthenticated attackers to retrieve private unfurl records by supplying predictable auto-increment primary key IDs to the unfurl endpoint. Attackers can enumerate or predict result IDs and query the endpoint without any session, user, or visibility checks to obtain rendered preview HTML, original URLs, and query strings from private conversations and other restricted content. |
| In createSessionInternal of PackageInstallerService.java, there is a possible way to permanently DoS the device due to a logic error in the code. This could lead to local denial of service with no additional execution privileges needed. User interaction is not needed for exploitation. |
| In onCreate of ContactsPickerActivity.kt, there is a possible misleading UI due to a tapjacking/overlay attack. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation. |
| In openFile of AppFuseBridge.java, there is a possible information disclosure due to a missing permission check. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation. |
| In the Linux kernel, the following vulnerability has been resolved:
nfsd: check client ownership when cancelling a copy-notify stateid
On the OFFLOAD_CANCEL path (clp != NULL), manage_cpntf_state() freed the
target cpntf state without checking ownership. The lookup key
st->si_opaque.so_id is allocated cyclically (guessable) and the embedded
clientid is the fixed per-net nn->s2s_cp_cl_id, so any authenticated
NFSv4.2 client could cancel and free another client's copy-notify
stateid.
Compare the creating clientid recorded in state->cp_p_clid against the
requesting client's cl_clientid and return nfserr_bad_stateid on a
mismatch instead of freeing the entry. |
| In the Linux kernel, the following vulnerability has been resolved:
ceph: cap delegated inode count in ceph_parse_deleg_inos()
ceph_parse_deleg_inos() decodes interval sets of delegated inode numbers
from an MDS create-with-delegation reply. For each set it reads a 64-bit
start and a 64-bit len with ceph_decode_64_safe(), which only validates
that the eight bytes are present in the message, not the value, and then
loops over len while inserting entries into s_delegated_inos.
len is fully attacker controlled. A malicious or compromised MDS can send
one huge interval, many intervals in one reply, duplicate intervals, or
repeated replies that accumulate delegated inodes on the same session.
The original code bounded none of these and could spin the insert loop or
grow the xarray without limit.
Bound both dimensions with a single enforcement point. Track the number
of delegated inodes held by each MDS session in an atomic counter and
grow it only in ceph_insert_deleg_ino(), which uses atomic_add_unless()
to refuse to push the count past CEPH_MAX_DELEG_INOS. Because that helper
is the only place the counter grows, the per-session population can never
exceed the cap, so no separate per-session pre-check is needed. The
counter is decremented when async create consumes a delegated inode or
when an insert fails, incremented when a delegated inode is restored,
initialized with the session xarray, and reset when reconnect destroys
the xarray.
A per-session cap alone still lets one reply spin the insert loop on
duplicate ranges without growing the counter, so also cap the aggregate
interval length accepted from a single reply. Together these bound both
the loop trip count per reply and the xarray population across replies.
The cap is a fixed, client-chosen constant rather than a value derived
from the MDS. mds_client_prealloc_inos is a userspace MDS configuration
option; it is never sent to the kernel client on the wire, and a
server-supplied bound could not be trusted for a defensive limit in any
case. The constant is set well above that option's documented default of
1000 (a generous multiple), so legitimate refill behavior is unaffected
while the CPU and xarray memory a malformed delegation stream can consume
stays bounded.
Impact: a malicious or compromised Ceph MDS can no longer make a client
spin through an unbounded delegated-inode interval or grow one session's
delegated-inode xarray without limit. |
| In the Linux kernel, the following vulnerability has been resolved:
jbd2: check need_resched() when skipping busy checkpoint buffers
journal_shrink_one_cp_list() skips busy checkpoint buffers when called
with JBD2_SHRINK_BUSY_SKIP. The continue statement on this path also
skips the need_resched() check at the end of the loop body.
Consequently, when a checkpoint list contains mostly busy buffers, the
shrinker can walk the entire list while holding journal->j_list_lock,
even when a reschedule has been requested. Large checkpoint lists under
memory pressure can therefore cause long lock hold times and leave other
CPUs spinning on j_list_lock, resulting in soft lockups or RCU stalls.
Route the busy-buffer path through the need_resched() check so that the
shrinker can release j_list_lock and reschedule promptly, restoring
parity with the clean-buffer path, which already checks need_resched().
This does not change which checkpoint buffers are eligible for removal. |
| In the Linux kernel, the following vulnerability has been resolved:
iommu/tegra241-cmdqv: Reject a vSID wider than the SID_MATCH field
tegra241_vintf_init_vsid() programs the guest-provided vSID into SID_MATCH,
whose VIRT_SID field spans bits [20:1] with bit 0 as the match-enable flag.
The HW therefore matches only a 20-bit Stream ID.
The bound check rejects only virt_sid > UINT_MAX, which admits a value far
wider than the field. The write "virt_sid << 1 | 0x1" then drops every bit
above 20: a virt_sid of 0x80000000 lands as SID_MATCH = 0x1, a valid match
on vSID 0, so the entry aliases the wrong Stream ID. Because vdev->virt_id
is guest-controlled, a VMM can trigger it.
Validate virt_sid against the field width with FIELD_MAX(), and program the
register with FIELD_PREP() so the value and the field stay consistent. |
| Concrete CMS before 9.5.3 evaluated the authorization check for an Express entry submission against the entity of the posted form rather than the entity identified by the dashboard route. As a result, a user permitted to add entries to one Express object could create entries in a different Express object outside their authorization scope, potentially polluting protected datasets, triggering workflows, or injecting content into administrative processes. The dashboard submit route resolved the mutated entity from the attacker-controlled route ID while the permission check validated the independently posted form's entity, and the submission proceeded because the two entities were never compared. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 5.1 with vector CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N. Thanks Yonatan Drori from Tenzai for reporting. |
| Concrete CMS below 9.5.3 does not perform an object-level authorization check when a Page Type was updated. The Types::submit() dashboard controller loaded and saved the Page Type identified by a user-supplied ptID without calling canEditPageType(), so a signed-in dashboard user permitted to edit one Page Type could modify the configuration of Page Types outside their assigned authorization boundary. The update_page_type token was validated but is action- and user-scoped rather than object-scoped, so it did not constrain which Page Type could be targeted. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 5.1 with vector CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N. Thanks Andrew Gonzalez for reporting. |
| Concrete CMS versions 9.5.0 through 9.5.2 are vulnerable to Open Redirect via the rcURL parameter. An attacker can craft a single link on the site's own domain that sends a user to an arbitrary external site immediately after authentication, facilitating phishing and credential theft. The same handling is present in the registration flow, giving a second entry point on sites with registration enabled. Concrete CMS versions prior to 9.5.0 do not include the rcURL parameter or this allowlist and are not affected. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 5.3 with vector CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N. Thanks Michal M. for reporting. |
| In the Linux kernel, the following vulnerability has been resolved:
io_uring/waitid: honor task_work cancellation
io_waitid_cb() may run through the fallback task_work path when
task_work_add() can no longer queue work to the originating task. The
fallback runs from a kworker and io_uring marks such task work as
canceled through tw.cancel.
io_waitid_cb() currently ignores tw.cancel and calls __do_wait().
waitid is task-context dependent: __do_wait() performs child lookup
relative to current, and the retry path also uses
current->signal->wait_chldexit. If the callback runs from the fallback
kworker, current is therefore not the task that submitted the request.
Honor tw.cancel before entering __do_wait(). Complete the request with
-ECANCELED and skip the siginfo copy, since canceled task work may run
without the submitting task's userspace execution context.
Keep the existing siginfo handling for normal waitid completion and
explicit cancellation. |
| Laci Synchroni is a decentralized mod and appearance sync server and plugin for Dalamud. Versions of the backend prior to 1.2.3 have an improper authentication vulnerability in the application's OAuth2 login flow. The application relies on client-side state by trusting the `UID` field inside the `Authentications` object of a user's local `config.json` file. By manually editing this local file on their PC prior to logging in, a user can supply an arbitrary UID. Because the server fails to validate that the authenticated OAuth2 identity matches the requested UID, an attacker can fully impersonate any target user and perform actions on their behalf. This issue has been resolved in version 1.2.3. The patch modifies `AuthorizeOauthAsync` inside the `SecretKeyAuthenticatorService` to strictly bind the lookup of the requested User ID (`requestedUid`) to the record of the successfully authenticated identity (`primaryUid`). The server will no longer load or return session tokens for a requested UID unless it matches the verified, authenticated database record. No known workarounds are available. |
| Improper restriction of XML external entity references in the RemoteQueryCachePlugin in AWS Advanced JDBC Wrapper 3.3.0 through 4.2.0 might allow an actor with write access to the shared cache infrastructure to disclose sensitive files from application hosts that read cached query results, including stored database and IAM role credentials, via crafted XML data in a cached column value.
To remediate this issue, users should upgrade to version 4.3.0 or later. |
| libp2p-rendezvous through 0.17.1 fails to validate registration TTL values in discovery responses, allowing attackers to trigger timer arithmetic overflow. A malicious rendezvous server can send a discovery response with an unbounded TTL value that causes the client node process to panic when computing the expiry timer. |
| Authorizer is an open-source, self-hostable authentication and authorization server. Prior to version 2.2.1, the `/authorize` endpoint accepts any `redirect_uri` without validating it against `AllowedOrigins`. When `response_type=token` or `response_type=id_token`, the server appends `access_token`, `id_token`, and `refresh_token` as query parameters and issues a 302 redirect to the attacker-supplied URL. An unauthenticated attacker can obtain the required `client_id` from the public `/graphql?query={meta{client_id}}` endpoint. A partial fix was applied in v2.0.1 to other handlers (`oauth_login`, `verify_email`, `magic_link_login`, `forgot_password`, `invite_members`, `oauth_callback`) but `/authorize` was not included. Version 2.2.1 contains a more complete fix. |
| Renovate before 44.11.3 fails to validate Link header destinations when following GitLab server pagination, allowing malicious servers to redirect credential-bearing requests. Attackers controlling a compromised GitLab server can specify a Link header pointing to attacker-controlled infrastructure to exfiltrate authentication credentials. |
| IBM DataStage on Cloud Pak for Data 5.4.0.0 could allow a remote authenticated attacker to manipulate runtime caches and cause a denial of service due to an insecure direct object reference. |
| A flaw was found in RESTEasy's SourceProvider. This vulnerability allows an unauthenticated attacker to perform an unauthenticated remote file read. By sending a specially crafted XML body with a DOCTYPE declaration referencing external entities to an endpoint that accepts application/xml and returns Source or StreamSource, the server can be tricked into resolving the entity and including sensitive file contents in the HTTP response. This is due to the SourceProvider.writeTo() method creating a SAXParser without disabling external entity resolution, leading to an XML External Entity (XXE) vulnerability. |
