CVE-2026-61611: Lychee album unlock brute-force attack

CVE-2026-61611 · Severity: high · CVSS 7.5 · Published 2026-10-15

Lychee is an open-source photo management application that allows users to protect albums with passwords.

An unauthenticated attacker knowing an album ID could automate password guesses and, if successful, gain unauthorized access to private photo collections.

How to fix

Fixed in: 7.6.1

Technical details

The POST /api/v2/Album::unlock endpoint lacked throttling, attempt counters, backoff mechanisms, or CAPTCHAs. The UnlockAlbumRequest::authorize() method permitted any unauthenticated caller to submit attempts, and Hash::check() verified each guess without limiting repeated failures. The vulnerability was fixed by adding rate limiting middleware (throttle:10,1) restricting requests to 10 per minute.
