CVE-2026-25591Public exploitNetwork attack vector

Authenticated service interruption via wildcard token search

Published Feb 24, 2026 · Updated Feb 24, 2026

SQL LIKE wildcard injection in New API before 0.10.8-alpha.10 allows remote authenticated users to interrupt service through token search. The SearchUserTokens path in model/token.go embeds unescaped keyword and token values between percent signs in parameterized LIKE patterns, so attacker-supplied % and _ expand the result set. A valid low-privilege session and a token-heavy account are required; concurrent requests can saturate database CPU, exhaust application memory, and block legitimate requests.
