{"cve":"CVE-2026-77467","nvd":{"published":"2026-10-15T17:17:27.727","modified":"2026-10-20T03:17:16.690","status":"Deferred","description":"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.","cvss_v4":{"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},"cvss_v3":null,"cwes":["CWE-400","CWE-770"],"references":["https://github.com/LycheeOrg/Lychee/commit/1e92846af4c2d259a225cf4517de17efba04f945","https://github.com/LycheeOrg/Lychee/pull/4511","https://github.com/LycheeOrg/Lychee/releases/tag/v7.7.0","https://github.com/LycheeOrg/Lychee/security/advisories/GHSA-6736-fhxv-3p79","https://github.com/LycheeOrg/Lychee/security/advisories/GHSA-6736-fhxv-3p79"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-77467","score":0.0034,"percentile":0.27273,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
