{"schema":"threatline.record/2","record":{"id":"CVE-2026-61610","aliases":["GHSA-qcqq-p4pq-7r77"],"summary":"Lychee: unauthenticated photo starring reveals existence of private photos when photos_star_visibility=anonymous","details":"Lychee is a free, open-source photo-management tool. Prior to 7.6.1, when photos_star_visibility is set to anonymous, POST /api/v2/Photo::highlight can fetch and modify a photo without confirming that the caller can see it. BaseApiRequest::validateResolved() invokes SetPhotosHighlightedRequest::processValidatedValues() before authorization, and PhotoPolicy::canHighlight() returns true for anonymous callers without a canSee check. An unauthenticated attacker who can guess photo identifiers can distinguish existing private photos through differing success and not-found responses and can change their is_highlighted state, including for photos in private or password-protected albums. The issue is limited to installations using the non-default anonymous star-visibility setting. This issue is fixed in version 7.6.1.","categories":["Unclassified"],"product":"Lychee","vendor":"LycheeOrg","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-61610","source_modified_at":"2026-10-20T02:48:31.094Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Lychee","vendor":"LycheeOrg","versions":[{"version":"< 7.6.1","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":2.3,"severity":"Low","kev":{"listed":false},"epss":{"probability":0.0023,"percentile":0.13129,"score_date":"2026-10-23"},"published_at":"2026-10-15T16:26:16.585Z","modified_at":"2026-10-20T02:48:31.094Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-61610","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-20T02:48:31.094Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-61610","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/LycheeOrg/Lychee/security/advisories/GHSA-qcqq-p4pq-7r77","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/LycheeOrg/Lychee/pull/4449","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/LycheeOrg/Lychee/commit/fe07567c176bbdcda7b276bb6d664dfcd47a9b00","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/LycheeOrg/Lychee/releases/tag/v7.6.1","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":"2026-10-20T02:48:06.704908Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-20T02:48:31.094Z","content_hash":"f6dd314acd0680bd143b8227b867e80a024e3c159b47774d18895a8e32117e60"}}
