{"id":"CVE-2026-61611","published":"2026-10-15T17:17:26.537","lastModified":"2026-10-15T21:08:49.703","description":"Lychee is a free, open-source photo-management tool. Prior to 7.6.1, POST /api/v2/Album::unlock has no throttle, attempt counter, backoff, CAPTCHA, or lockout. UnlockAlbumRequest::authorize() permits any caller to submit attempts, and app/Actions/Album/Unlock.php verifies each guess with Hash::check without limiting repeated failures. A remote unauthenticated attacker who knows or can obtain an album identifier can automate password guesses against a password-protected album and, if the password is recovered, gain access to its private photo collection. This issue is fixed in version 7.6.1.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-307"],"vendors":[],"products":[],"references":[{"url":"https://github.com/LycheeOrg/Lychee/commit/592291458a3373114a21412956fd23cfcda32aba","tags":[]},{"url":"https://github.com/LycheeOrg/Lychee/pull/4448","tags":[]},{"url":"https://github.com/LycheeOrg/Lychee/releases/tag/v7.6.1","tags":[]},{"url":"https://github.com/LycheeOrg/Lychee/security/advisories/GHSA-48vf-fwx6-2ph6","tags":[]}],"exploitRefs":[{"url":"https://github.com/LycheeOrg/Lychee/commit/592291458a3373114a21412956fd23cfcda32aba","tags":[]},{"url":"https://github.com/LycheeOrg/Lychee/pull/4448","tags":[]},{"url":"https://github.com/LycheeOrg/Lychee/releases/tag/v7.6.1","tags":[]},{"url":"https://github.com/LycheeOrg/Lychee/security/advisories/GHSA-48vf-fwx6-2ph6","tags":[]}],"hasPoc":true,"ai":null}
