CWE-362
Allowed-with-ReviewConcurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
Abstraction: Class · Status: Draft
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
3524 vulnerabilities reference this CWE, most recent first.

Title
Reachy Mini Bluetooth PIN authentication can be bypassed by racing an authenticated device
Summary
The Reachy Mini Bluetooth service asks a connecting device for a PIN before it will accept commands. The check protects the session but not the caller, so an attacker in Bluetooth range can ride along on someone else's successful authentication.
The authenticated state is kept in a single shared flag on the service instance rather than per device. BlueZ passes the calling device's identity to the characteristic write handler in the options argument, but WriteValue(self, value, options) in src/reachy_mini/daemon/app/services/bluetooth/bluetooth_service.py ignores options entirely. The handler therefore has no idea which device sent a given write, and it cannot tell the authenticated one from any other.
Once any device completes the PIN exchange, the flag is set and every nearby device can send CMD_ commands until it resets. An attacker simply waits within radio range for a legitimate user to authenticate, then writes commands into the same window. No PIN is ever guessed or brute-forced.
This is the second step of a three-step chain that JFrog documented against the robot. The first is the unrestricted file upload in the media sounds API, tracked as CVE-2026-55419, which places an attacker-controlled script on the filesystem. This issue then provides command access over Bluetooth. The third is the Bluetooth command handler path traversal, tracked as CVE-2026-62661, which runs that script as root.

CVE-2026-94584 (GCVE-0-2026-94584)

Summary
A race condition and thread-safety vulnerability exists in the web management daemon of Brocade Fabric OS versions before 10.0.1. When handling user authentication requests across a multi-threaded execution pool, this race condition causes PAM modules to process stale or incorrect client IP addresses and switch context numbers. This leads to inaccurate audit records and potential access control bypasses where AAA evaluation or Calling-Station-ID ACL policies rely on client IP attributes.

Summary
A race condition vulnerability exists in the request processing logic of the REST management interface on Brocade Fabric OS versions before 10.0.1. When handling concurrent incoming network management FCIP requests, a timing window exists between when a request populates the address variable and when the service constructs and returns the response context. As a result, the first request adopts the modified context, causing the service to return sensitive management details or configuration data belonging to the second context back to the original requester.

Title
Untrusted request routing and forged acknowledgements permit copy-workflow manipulation in Progress ShareFile Storage Zones Controller
Summary
In Progress ShareFile Storage Zones Controller v5.12.6 and below, processing of queue items can send acknowledgements to an unvalidated callback URL, this behavior together with a race condition allows the attacker to cause FileCopyService to consume attacker-controlled metadata and content. Exploitation requires control over copy queue work and a race condition.

Title
FreeRDP Server before 3.31.0 Use-After-Free via DRDYNVC
Summary
FreeRDP server versions before 3.31.0 contain a use-after-free vulnerability in the DRDYNVC parser that dereferences a channel pointer after releasing the synchronization lock. Authenticated clients can race AUDIN channel closure messages against DRDYNVC data parsing to trigger heap-use-after-free when accessing freed channel objects.

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.
