Alert meAnalysisAIv1 – Mar 12, 2026
OliveTin versions prior to 3000.10.3 are vulnerable to unauthenticated denial-of-service attacks when OAuth2 authentication is enabled, allowing remote attackers to crash the application by sending concurrent requests to the login endpoint. The vulnerability stems from unsynchronized access to shared state during OAuth2 processing, triggering a Go runtime panic. Public exploit code exists for this high-severity flaw, which is patched in version 3000.10.3 and later.
Earlier versions of this analysis (1)
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. [CVSS 7.5 HIGH]
RemediationAI
A vendor patch is available — apply it immediately. Fixed in version 3000.10.3.. Restrict network access to the affected service where possible.

Classified as CWE-362 (Race Condition). Affects Olivetin. 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 30

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.
Executive ViewAI
OliveTin versions prior to 3.0.10.3 contain an unauthenticated denial-of-service vulnerability in the OAuth2 login flow that could render the web interface unavailable to legitimate users. Any organization using OliveTin for command automation should prioritize patching to prevent service disruption.
Apply vendor patch.
