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.","state":0,"publishedAt":"2026-10-15T16:34:35.236+00:00","modifiedAt":"2026-10-20T02:50:18.889+00:00","affected":[{"ecosystem":"Vendor product","name":"Lychee","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"LycheeOrg\",\n                    \"product\": \"Lychee\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 7.7.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":7.1,"severity":"HIGH"}],"references":["https://github.com/LycheeOrg/Lychee/security/advisories/GHSA-6736-fhxv-3p79","https://github.com/LycheeOrg/Lychee/pull/4511","https://github.com/LycheeOrg/Lychee/commit/1e92846af4c2d259a225cf4517de17efba04f945","https://github.com/LycheeOrg/Lychee/releases/tag/v7.7.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-77467","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-77467","identifiers":["CVE-2026-77467"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
