{"affected":[{"product":"Stirling-PDF","source":"CNA: GitHub_M","vendor":"Stirling-Tools","versions":[{"status":"affected","version":"< 3.0.0"}]}],"cveId":"CVE-2026-119343","cwes":["CWE-73","CWE-918"],"description":"Stirling-PDF is a locally hosted web application that facilitates various operations on PDF files. Prior to 3.0.0, POST /api/v1/ai/tools/create-pdf-from-html-agent accepts attacker-controlled htmlContent and passes it to WeasyPrint without CustomHtmlSanitizer, unlike the sanitized /api/v1/convert/html/pdf control path. HTTP and HTTPS resource references can make server-side requests to internal or cloud-metadata destinations, while file references can embed local content readable by the Stirling-PDF process into the generated PDF. The endpoint is reachable without credentials when security.enableLogin is false, and the flaw is distinct from earlier Stirling-PDF WeasyPrint vulnerabilities in older conversion paths. This issue is fixed in version 3.0.0.","epss":{"date":"2026-11-02","percentile":0.20922,"score":0.00284},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://github.com/Stirling-Tools/Stirling-PDF/security/advisories/GHSA-3x7x-943g-269w"}],"kev":null,"metrics":[{"score":6.8,"severity":"medium","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},{"score":6.8,"severity":"medium","source":"NVD: security-advisories@github.com","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N","version":"3.1"}],"modifiedAt":1793636251753,"publishedAt":1793392308374,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/Stirling-Tools/Stirling-PDF/security/advisories/GHSA-3x7x-943g-269w"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/Stirling-Tools/Stirling-PDF/pull/7018"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/Stirling-Tools/Stirling-PDF/commit/0570c4c4d9e7bf4786a02ab770ef75f116ac3719"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/Stirling-Tools/Stirling-PDF/releases/tag/v3.0.0"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://github.com/Stirling-Tools/Stirling-PDF/security/advisories/GHSA-3x7x-943g-269w"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/Stirling-Tools/Stirling-PDF/commit/0570c4c4d9e7bf4786a02ab770ef75f116ac3719"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/Stirling-Tools/Stirling-PDF/pull/7018"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/Stirling-Tools/Stirling-PDF/releases/tag/v3.0.0"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/Stirling-Tools/Stirling-PDF/security/advisories/GHSA-3x7x-943g-269w"},{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":[],"url":"https://github.com/Stirling-Tools/Stirling-PDF/security/advisories/GHSA-3x7x-943g-269w"}],"remediation":[],"revision":"f505b24e152fc0ed8f79f1af3f2bf884201a93be5420a85cd58def954ca40c2d","sources":[{"modifiedAt":1793631827434,"name":"CNA: GitHub_M","retrievedAt":1793635733280,"url":"https://www.cve.org/CVERecord?id=CVE-2026-119343"},{"modifiedAt":1793636251753,"name":"NVD","retrievedAt":1793643475631,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-119343"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793635737312,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-119343"}],"ssvc":{"assessedAt":1793631789523,"automatable":"no","exploitation":"poc","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Stirling-PDF: AI create-pdf-from-html-agent skips HTML sanitization enabling WeasyPrint SSRF and local file read","updatedAt":1793643475631}
