{"schema":"threatline.record/2","record":{"id":"CVE-2026-77467","aliases":["GHSA-6736-fhxv-3p79"],"summary":"Lychee: A single 383-byte PDF causes ~184 seconds of CPU consumption in the real processing path","details":"Lychee is a free, open-source photo-management tool. Prior to 7.7.0, Lychee enables ImageMagick PDF support with Ghostscript but does not apply an effective pre-render limit to PDF page dimensions in ImagickHandler::loadPdf(). An authenticated user who can upload a small PDF with an oversized /MediaBox can cause Imagick::readImage() to consume substantial CPU before failing to produce an image. When QUEUE_CONNECTION selects synchronous processing the request can occupy a web worker, while the official asynchronous Docker configuration can clog the shared image-processing queue and delay other work. The advisory did not identify a Ghostscript sandbox escape. This issue is fixed in version 7.7.0.","categories":["Unclassified"],"product":"Lychee","vendor":"LycheeOrg","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-77467","source_modified_at":"2026-10-20T02:50:18.889Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Lychee","vendor":"LycheeOrg","versions":[{"version":"< 7.7.0","status":"affected"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/LycheeOrg/Lychee/security/advisories/GHSA-6736-fhxv-3p79","source_modified_at":"2026-08-20T20:28:46Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"ecosystem":"composer","name":"lychee-org/lychee"},"range":"<= 7.6.4"}],"fixed_versions":[],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00268,"percentile":0.1797,"score_date":"2026-10-23"},"published_at":"2026-10-15T16:34:35.236Z","modified_at":"2026-10-20T02:50:18.889Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-77467","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-20T02:50:18.889Z"},{"source":"GitHub Advisory Database","url":"https://github.com/LycheeOrg/Lychee/security/advisories/GHSA-6736-fhxv-3p79","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-08-20T20:28:46Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-77467","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-6736-fhxv-3p79","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/LycheeOrg/Lychee/pull/4511","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/LycheeOrg/Lychee/commit/1e92846af4c2d259a225cf4517de17efba04f945","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/LycheeOrg/Lychee/releases/tag/v7.7.0","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":"no","technical_impact":"partial","assessed_at":"2026-10-20T02:49:32.958809Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-20T02:50:18.889Z","content_hash":"9f210496e86cfddd7cb758426392881bcc2155b20ee3e94e3f66741febcb4742"}}
