Unauthenticated account access via unlimited password guesses
Published Jan 9, 2026 · Updated Jan 9, 2026
Authentication bypass in Shiori 1.7.4 and earlier allows remote attackers to access accounts through brute-force password guessing. The login page accepts repeated POST requests without rate limiting, allowing each password guess to be tested against an account. No initial authentication or user interaction is required; success depends on discovering a valid password and grants the access assigned to that account.
