CVE-2026-67437 Details
Description
OliveTin gives access to predefined shell commands from a web interface. From 3000.0.0 until 3000.17.0, the service/internal/auth/otoauth2/restapi_auth_oauth2.go OAuth2 login handler stores per-login state in the registeredStates map on every /oauth/login request without expiring, deleting, or bounding entries, allowing an unauthenticated attacker to exhaust memory and cause a denial of service. This issue is fixed in version 3000.17.0.
A denial-of-service vulnerability has been identified in OliveTin versions 3000.0.0 prior to 3000.17.0. The issue arises in the OAuth2 login handler, which stores state information in an unbounded in-memory map called 'registeredStates'. This map grows indefinitely with each '/oauth/login' request, as there is no mechanism to expire or delete entries. An unauthenticated attacker can exploit this by sending a high volume of login requests, leading to excessive memory consumption and causing the server to become unresponsive.
Users can upgrade to OliveTin version 3000.17.0, which addresses this vulnerability by introducing a maximum entry limit and a cleanup mechanism for the OAuth2 state management.
