Vulnerability in github.com/OliveTin/OliveTin (CVE-2026-48709)
Summary
Vulnerability in github.com/OliveTin/OliveTin (CVE-2026-48709). Risk of unauthorized operations or information disclosure. Exploitable via ValidateArgumentType. Mitigation: upgrade to 0.0.0-20260521230847-a3865704c854 or later.
Original description
The description as published by the source.
OliveTin gives access to predefined shell commands from a web interface. In versions 3000.0.0 and prior, The ValidateArgumentType RPC endpoint in service/internal/api/api.go does not perform any authentication or authorization checks. Unlike all other data-returning API endpoints, it does not call auth.UserFromApiCall or checkDashboardAccess. When AuthRequireGuestsToLogin is enabled (the security-conscious configuration), this endpoint remains accessible to unauthenticated users and can be used as an oracle to enumerate valid action binding IDs and their argument configurations. This issue has been fixed in version 3000.13.0.
