Detailsinfo

A vulnerability was found in akhilrex Podgrab (the affected version is unknown). It has been rated as problematic. Affected by this issue is the function Wshandler/HandleWebsocketMessages of the component WebSocket Handler. The manipulation of the argument activePlayers/allConnections with an unknown input leads to a race condition vulnerability. Using CWE to declare the problem leads to CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence 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 that is operating concurrently. Impacted is availability. CVE summarizes:

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.

The advisory is available at gist.github.com. This vulnerability is handled as CVE-2026-104057 since 10/01/2026. The exploitation is known to be easy. The attack may be launched remotely.
