Title
ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 Heap Buffer Overflow via Concurrent Security Policy Access
Summary
ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 lacks proper synchronization when the security policy is accessed, so simultaneous reads and writes of the policy by multiple threads trigger a race condition that causes a heap buffer over-write. An attacker able to induce concurrent security policy access can crash the application, causing a denial of service.

Title
MISP Email OTP Race Condition Allows One-Time Password to Be Consumed by Multiple Concurrent Requests
Summary
MISP contains a race condition in the email-based one-time password (OTP) login flow. When two HTTP requests carrying the same valid OTP are submitted concurrently, both can successfully authenticate and establish a session. The root cause is that the OTP value is read from the shared store, validated, and then deleted in separate non-atomic steps, allowing a second in-flight request to read the same value before the first request's deletion takes effect.
Preconditions:
- The target MISP instance has email OTP login enabled.
- The attacker possesses a valid, unexpired OTP (e.g., via email interception or social engineering).
- The attacker can issue two HTTP POST requests in close temporal proximity.
Impact:
- The one-time-use guarantee of the OTP is violated; a single code can yield two authenticated sessions.
- This weakens the authentication control and may facilitate unauthorized access if the OTP is shared or intercepted.

fix: [login] Let only one request spend an e-mailed OTP | 810e97a648a3… |
Fix summary
The fix makes OTP consumption atomic by moving the deletion of the OTP from the shared store into the validation condition itself. The return value of the delete operation (1 if the key was actually removed, 0 otherwise) is now part of the success check, so only the request that successfully removes the OTP from the store is permitted to proceed with login. A session-state cleanup call was also added to remove the OTP user reference from the session.
Patch summary
In UsersController::email_otp(), the $redis->del() call was moved from after the hash_equals comparison into the if-condition as an additional conjunct. The condition now requires $redis->del('misp:otp:' . $user_id) === 1, meaning only the request whose delete actually removed the key (returning 1) can proceed to Auth->login(). A $this->Session->delete('email_otp_user') call was added before the login step to clean up session state. Net change: 6 insertions, 3 deletions in one file.
CVSS rationale
AV:N: Exploitation occurs over the network via HTTP POST. AC:H: Exploiting the race condition requires precise timing of two concurrent requests so both read the OTP before either deletes it; this is non-trivial to achieve reliably. AT:N: No data corruption or manipulation is required. PR:N: The attacker does not need prior authentication to MISP; they only need possession of a valid OTP (e.g., intercepted email). UI:N: No victim interaction beyond the initial login flow is needed. VC:N: No direct confidentiality loss of system data. VI:L: The one-time-use property of the OTP is violated, allowing a second authenticated session. VA:N: No availability impact. SC/SI:L: Limited integrity impact on the authentication process; no cross-system impact. SA:N: No impact on security authority.
Weakness rationale
- CWE-362 The OTP stored in Redis is a shared resource accessed by concurrent HTTP requests. The original code performed read, compare, and delete as separate non-atomic operations, allowing two concurrent requests to both read and validate the same OTP before either deletes it. This is a textbook race condition on a shared resource.
- CWE-367 The check (reading and comparing the OTP) and the use (logging in) are separated in time, and the state (OTP presence in the store) can change between the two steps due to a concurrent request. This is a TOCTOU variant of the race condition.
Attack pattern rationale
- CAPEC-111 The attack pattern involves an adversary issuing two or more concurrent requests to exploit a non-atomic check-and-use sequence on a shared resource (the OTP in Redis). CAPEC-111 directly describes exploiting timing dependencies between sub-processes. This is the closest CAPEC to the observed vulnerability; no more specific CAPEC for OTP replay via race condition exists in the CAPEC catalog.
Assumptions to verify
- The exact affected version range is not explicitly stated in the patch; the tag boundary v2.5.48 with 39 commits after the fix suggests the fix landed shortly after that tag, but the precise first-fixed version is unconfirmed.
- The CAPEC-111 mapping is the closest available; no CAPEC specifically covers OTP replay via race condition, so this is the best-fit pattern.
- CVSS AC:H assumes the race window is narrow and requires precise timing; if the Redis round-trip latency is large, exploitation may be easier, but no evidence supports lowering AC.
- The commit message states the issue was 'found during the internal review, not externally reported,' but no specific individual is named as finder, so no finder credit is assigned.
- PR:N assumes the attacker obtains the OTP through out-of-band means (email interception); if MISP requires prior authentication to request an OTP, PR could be L.

Title
Backstage: Improper task state validation in Scaffolder backend
Summary
Backstage is an open framework for building developer portals. Prior to 3.3.1, 3.4.1, 4.0.3 and 4.1.0, the @backstage/plugin-scaffolder-backend package is affected by improper task state validation in scaffolder backend. An authenticated user with permission to create and access Scaffolder tasks may, under specific timing and deployment conditions, affect files accessible to the Backstage backend. If backend application files are writable, the confidentiality, integrity, and availability of the backend may be compromised. This issue is fixed in versions 3.3.1, 3.4.1, 4.0.3 and 4.1.0.

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.

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.
