{"schema":"threatline.record/2","record":{"id":"CVE-2026-57568","aliases":["GHSA-pgfr-x389-5p2h"],"summary":"Lychee: Stored XSS via Markdown javascript: Links in Photo and Album Descriptions (Gallery View)","details":"Lychee is a free, open-source photo-management tool. Prior to 7.6.0, Lychee permits an authenticated user with album-edit permissions to store a javascript URI in an album or photo Markdown description because config/markdown.php enables allow_unsafe_links. app/Http/Resources/Models/Utils/PreformattedPhotoData.php and app/Http/Resources/Models/Utils/PreFormattedAlbumData.php convert the description to HTML, and the gallery components PhotoDetails.vue, Overlay.vue, PhotoThumb.vue, AlbumHero.vue, and AlbumCard.vue render that HTML with v-html. A visitor, including an unauthenticated visitor to a public album, who clicks the rendered link executes attacker-controlled JavaScript in the Lychee origin, which can expose session data or enable authenticated requests in the victim's context. This gallery-view flaw is distinct from CVE-2026-33738, which addressed feed rendering. This issue is fixed in version 7.6.0.","categories":["Unclassified"],"product":"Lychee","vendor":"LycheeOrg","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-57568","source_modified_at":"2026-10-16T17:13:21.565Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Lychee","vendor":"LycheeOrg","versions":[{"version":"< 7.6.0","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":5.7,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00278,"percentile":0.19209,"score_date":"2026-10-23"},"published_at":"2026-10-15T16:22:30.323Z","modified_at":"2026-10-16T17:13:21.565Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-57568","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T17:13:21.565Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-57568","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-pgfr-x389-5p2h","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/LycheeOrg/Lychee/pull/4377","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/LycheeOrg/Lychee/commit/f0604ead5889bfed404d6f5e1a9205f945172c7e","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/LycheeOrg/Lychee/releases/tag/v7.6.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-15T20:24:41.497357Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-16T17:13:21.565Z","content_hash":"8ea69d8454a2a4381ff1420fb9dde88802e4393750bd37d7d8834adeb8e03c62"}}
