High (7.5) in olivetin olivetin. EPSS 0.5% chance of exploitation in the next 30 days. Fixed in github.com/OliveTin/OliveTin 0.0.0-20260301235225-f044d90d5525c.
OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.10.3, an unauthenticated denial-of-service vulnerability exists in OliveTin’s OAuth2 login flow. Concurrent requests to /oauth/login can trigger unsynchronized access to a shared registeredStates map, causing a Go runtime panic (fatal error: concurrent map writes) and process termination. This allows remote attackers to crash the service when OAuth2 is enabled. This issue has been patched in version 3000.10.3.
