Title
Obot 0.25.0 before 0.25.6 and 0.26.0 before 0.26.1 Race Condition Restores Revoked Group Membership
Summary
Obot 0.25.0 before 0.25.6 and 0.26.0 before 0.26.1 contains a race condition in auth provider group refreshes that can restore group memberships just revoked in the identity provider. When overlapping refreshes for the same user commit out of order, stale memberships are persisted and the user retains revoked group-based access for about ten minutes.

Title
Nezha 1.8.0 before 2.3.13 Deadlock DoS via notification-group endpoints
Summary
Nezha from 1.8.0 before 2.3.13 contains a lock-order inversion in UpdateGroup and DeleteGroup that allows authenticated non-admin users to deadlock the alerting subsystem. Attackers can concurrently call the notification-group and batch-delete endpoints with oversized id lists to widen the race and close an ABBA cycle, permanently killing alert delivery until restart.

Title
Plane: InstanceAdminSignUpEndpoint TOCTOU race allows two concurrent unauthenticated callers to both bootstrap as Plane instance admins
Summary
Plane is an open-source project management tool. From 0.13 until 1.4.0, InstanceAdminSignUpEndpoint in apps/api/plane/license/api/views/admin.py:89-117, 173-229 uses InstanceAdmin.objects.first() for the first-admin check and performs account creation without an atomic transaction, row lock, uniqueness guard, or advisory lock. Two concurrent unauthenticated requests with different email addresses can both observe that no instance administrator exists, create separate User and InstanceAdmin rows, and receive sessions with instance-admin authority. This allows an attacker to share unrestricted instance administration with the legitimate operator. This issue is fixed in 1.4.0.

Title
Wasmtime: Preemption and traps during bulk operations enable breaking internal VM state
Summary
Wasmtime is a runtime for WebAssembly. From 46.0.0 until 46.0.2 and 47.0.3, fuel and epoch preemption checks inside bulk operations including memory.copy, table.grow, and array.copy can expose invalid intermediate state when an embedder mutates a Store in Store::epoch_deadline_callback or continues using a Store after cancellation or a trap. A cancelled non-nullable table growth can leave null elements, linear-memory growth during memory.copy can invalidate retained raw pointers, and callback-triggered garbage collection during array.copy can invalidate GC pointers, resulting in a crash, invalid memory access, or GC heap corruption. Embeddings whose callbacks only access the host data in Store<T>, and embeddings that discard a Store after timeout or epoch deadline, are not affected. This issue is fixed in versions 46.0.2 and 47.0.3.

A cancelled non-nullable table growth can leave null elements, linear-memory growth during memory.copy can invalidate retained raw pointers, and callback-triggered garbage collection during array.copy can invalidate GC pointers, resulting in a crash, invalid memory access, or GC heap corruption. Embeddings whose callbacks only access the host data in Store\u003cT\u003e, and embeddings that discard a Store after timeout or epoch deadline, are not affected.

Title
Apache Struts: Shared message formatter exposes date and time values across concurrent requests
Summary
Concurrent execution using shared resource with improper synchronization ('race condition') vulnerability in Apache Struts. Where a localized message formats a date or time argument, the formatter retained for that message by the application-wide text provider is used by concurrently served requests without isolation, so a value belonging to one user can appear in another user's response, or the rendering can fail and surface as a server error. Applications whose localized messages format no date or time arguments are not affected.
This issue affects Apache Struts: from 2.0.0 through 2.3.37, from 2.5.0 through 2.5.33, from 6.0.0 through 6.11.0, from 7.0.0 through 7.3.0.
Users are recommended to upgrade to version 6.12.0 or 7.4.0, which fixes the issue.

Title
Podgrab Unauthenticated DoS via Concurrent Map Access in WebSocket Handler
Summary
Podgrab contains an unauthenticated denial-of-service vulnerability caused by unsynchronized concurrent access to shared maps (activePlayers and allConnections) in its WebSocket handler, where Wshandler and HandleWebsocketMessages goroutines read and write these maps without a mutex. A remote attacker can open multiple WebSocket connections to the /ws endpoint and send messages in a loop to trigger a Go runtime data race that crashes the process, causing a denial of service that requires operator intervention to restore service.

Title
MISP HOTP Token Replay via Stale Session-Cached Counter Allows Second-Factor Authentication Bypass
Summary
MISP contains a vulnerability in its one-time password (OTP) authentication flow that allows replay of a consumed HOTP (paper) token and rewinding of the token counter.
The HOTP verification logic compared the submitted token against a counter value that was cached in the user's session at the time the password was entered, rather than against the authoritative counter stored in the database. Because the session-cached counter is not updated after a token is successfully consumed, an attacker who holds a valid session (password already submitted) can reuse a previously burned HOTP token. The stale cached counter still matches the replayed token, granting a second successful authentication and effectively rewinding the counter state.
Preconditions:
- The target user has HOTP (paper token) second-factor authentication enabled.
- The attacker possesses a valid session in which the password step has already been completed (the OTP step is pending).
- The attacker has access to at least one HOTP token value (e.g., a paper token list).
Security impact:
- Bypass of the second authentication factor, allowing unauthorized access to a user's MISP account.
- Corruption of the HOTP counter state, potentially invalidating subsequent legitimate tokens or enabling further replays.
Affected versions: <2.5.48.

fix: [security] Burn paper OTP tokens against the stored | 9ec05e4a3d95… |
Fix summary
The fix replaces the session-cached HOTP counter lookup with a direct read of the authoritative counter from the database, performed under a Redis-based distributed lock scoped to the user. The token is verified against the current stored counter, the counter is incremented and persisted atomically within the locked section, and the lock is released in a finally block. Additionally, the cached OTP user session entry is deleted immediately after a successful login (for both TOTP and HOTP paths), preventing the stale session state from being reused.
Patch summary
In UsersController::otp(), the inline HOTP verification block (which used the session-cached $user['hotp_counter']) is replaced with a call to a new private method __consumeHotp(). This method acquires a Redis SETNX lock (misp:otp:hotp_lock:{userId}, 10 s TTL), re-fetches the user's totp secret and hotp_counter from the database, verifies the submitted OTP against the stored counter, increments and saves the counter, and releases the lock in a finally block. The otp_user session key is now deleted after both TOTP and HOTP successful login paths. Net change: +36 / -5 lines in app/Controller/UsersController.php.
CVSS rationale
AV:N – MISP is a network-accessible web application. AC:H – exploitation requires a valid session with the password step already completed, possession of a valid HOTP token value, and the session must still hold the stale cached counter; multiple preconditions must align. AT:N – no manipulation of the target system is needed. PR:L – the attacker must be an authenticated user with a pending OTP session. UI:N – no additional user interaction is required beyond the initial login flow. VC:H – successful exploitation grants full access to the target user's MISP account and its data. VI:H – the attacker can perform any action the user is authorized to perform, and the counter corruption may affect subsequent legitimate authentication. VA:N – no denial-of-service impact is evident. SC/SI/SA:N – no secondary system impact is indicated by the patch.
Weakness rationale
- CWE-362 The HOTP counter is shared mutable state accessed without synchronization. The session-cached copy becomes stale relative to the database copy, and no lock is held during read-verify-increment, allowing a concurrent or replayed request to operate on the old value.
- CWE-287 The OTP verification logic accepts a token that has already been consumed because it compares against a stale cached counter rather than the authoritative stored counter, effectively weakening the second-factor authentication check.
Attack pattern rationale
- CAPEC-111 The vulnerability is exploited by exploiting the time window between the session-cached counter being set (at password entry) and the token being consumed, allowing a replayed token to be validated against the stale value. CAPEC-111 (Race Condition) is the closest available CAPEC pattern; the attack is not a classic TOCTOU on a file or memory location but rather a stale-cache race on a shared counter, which falls under the broader race-condition category. No more specific CAPEC for session-cached credential state replay exists in the CAPEC catalog, so this is the best available match.
Assumptions to verify
- The tag_version_boundary metadata (v2.5.48, 41 commits after fix) is interpreted as the first release containing the fix; no explicit fixed_version or affected_version was provided in the metadata.
- The CAPEC-111 mapping is the closest available pattern; the vulnerability is specifically a stale-session-cache replay rather than a classic TOCTOU race, and no more precise CAPEC exists in the catalog.
- CVSS PR:L assumes the attacker already has a valid authenticated session (password step completed); if the threat model requires unauthenticated access, PR would be None but AC would remain High.
- The Redis lock is assumed to be available in the deployment; if Redis is not configured, the locking mechanism may be bypassed, though this is a deployment concern not reflected in the patch.
- The Co-Authored-By line references an AI assistant; it is recorded as a tool credit rather than a human remediation developer.

Mitigation
Architecture and Design
In languages that support it, use synchronization primitives. Only wrap these around critical code to minimize the impact on performance.
Mitigation
Architecture and Design
Use thread-safe capabilities such as the data access abstraction in Spring.
Mitigation
Architecture and Design
- Minimize the usage of shared resources in order to remove as much complexity as possible from the control flow and to reduce the likelihood of unexpected conditions occurring.
- Additionally, this will minimize the amount of synchronization necessary and may even help to reduce the likelihood of a denial of service where an attacker may be able to repeatedly trigger a critical section (CWE-400).
Mitigation
Implementation
When using multithreading and operating on shared variables, only use thread-safe functions.
Mitigation
Implementation
Use atomic operations on shared variables. Be wary of innocent-looking constructs such as "x++". This may appear atomic at the code layer, but it is actually non-atomic at the instruction layer, since it involves a read, followed by a computation, followed by a write.
Mitigation
Implementation
Use a mutex if available, but be sure to avoid related weaknesses such as CWE-412.
Mitigation
Implementation
Avoid double-checked locking (CWE-609) and other implementation errors that arise when trying to avoid the overhead of synchronization.
Mitigation
Implementation
Disable interrupts or signals over critical parts of the code, but also make sure that the code does not go into a large or infinite loop.
Mitigation
Implementation
Use the volatile type modifier for critical variables to avoid unexpected compiler optimization or reordering. This does not necessarily solve the synchronization problem, but it can help.
Mitigation MIT-17
Architecture and Design
Operation
Strategy: Environment Hardening
Run your code using the lowest privileges that are required to accomplish the necessary tasks [REF-76]. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
CAPEC-26: Leveraging Race Conditions
The adversary targets a race condition occurring when multiple processes access and manipulate the same resource concurrently, and the outcome of the execution depends on the particular order in which the access takes place. The adversary can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance, a race condition can occur while accessing a file: the adversary can trick the system by replacing the original file with their version and cause the system to read the malicious file.
CAPEC-29: Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions
This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. A typical example is file access. The adversary can leverage a file access race condition by "running the race", meaning that they would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the adversary could replace or modify the file, causing the application to behave unexpectedly.
