CVE-2026-28790
Prior to version 3000.11.0, OliveTin allows an unauthenticated guest to terminate running actions through KillAction even when authRequireGuestsToLogin: true is enabled.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.65%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.11.0, OliveTin allows an unauthenticated guest to terminate running actions through KillAction even when authRequireGuestsToLogin: true is enabled. Guests are correctly blocked from dashboard access, but can still call the KillAction RPC directly and successfully stop a running action. This is a broken access control issue that causes unauthorized denial of service against legitimate action executions. This issue has been patched in version 3000.11.0.
