{"schema":"threatline.record/2","record":{"id":"CVE-2026-61838","aliases":["GHSA-735c-2wqc-x29r"],"summary":"Lychee: Album password bypass in ZIP downloads","details":"Lychee is a free, open-source photo-management tool. Prior to 7.6.3, GET /api/v2/Zip authorizes album and photo archives through AlbumPolicy::canDownload() and PhotoPolicy::canDownload() without first enforcing AlbumPolicy::canAccess(). For a public, password-protected album with grants_download enabled, an unauthenticated attacker who knows the shared album identifier can download a ZIP archive without supplying the password or unlocking the album, even though browsing endpoints deny access. The archive exposes the album's photos and can include full-resolution originals and associated metadata when grants_full_photo_access is enabled. This issue is fixed in version 7.6.3.","categories":["Unclassified"],"product":"Lychee","vendor":"LycheeOrg","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-61838","source_modified_at":"2026-10-15T18:31:13.925Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Lychee","vendor":"LycheeOrg","versions":[{"status":"affected","version":"< 7.6.3"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/LycheeOrg/Lychee/security/advisories/GHSA-735c-2wqc-x29r","source_modified_at":"2026-07-13T14:28:56Z","fetched_at":"2026-10-24T10:48:42.330819Z","package":{"ecosystem":"composer","name":" lychee-org/lychee"},"range":"<= 7.6.2"}],"fixed_versions":[],"cvss":8.2,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00422,"percentile":0.35464,"score_date":"2026-10-23"},"published_at":"2026-10-15T16:32:37.392Z","modified_at":"2026-10-15T18:31:13.925Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-61838","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T18:31:13.925Z"},{"source":"GitHub Advisory Database","url":"https://github.com/LycheeOrg/Lychee/security/advisories/GHSA-735c-2wqc-x29r","fetched_at":"2026-10-24T10:48:42.330819Z","source_modified_at":"2026-07-13T14:28:56Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-61838","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/LycheeOrg/Lychee/security/advisories/GHSA-735c-2wqc-x29r","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/LycheeOrg/Lychee/pull/4459","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/LycheeOrg/Lychee/commit/4366dd0e721126dffe29659afec93aee9c1db711","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/LycheeOrg/Lychee/releases/tag/v7.6.3","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-15T18:30:52.301216Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T18:31:13.925Z","content_hash":"ad56ccd175c41ea716f4303f545dc34487872d7ceeea8648e883398551a2926f"}}
