In version 2.7.3, the /api/v1/convert/eml/pdf endpoint with parameter downloadHtml=true returns unsanitized HTML from the email body with Content-Type: text/html. An attacker who sends a malicious email to a Stirling-PDF user can achieve JavaScript execution when that user exports the email using the \"Download HTML intermediate file\" feature. Version 2.8.0 fixes the issue.","published":"2026-03-26T17:16:42.000Z","lastModified":"2026-06-17T10:38:31.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":6.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},"cwe":["CWE-79"],"affected":["stirling/stirling pdf"],"epss":{"score":0.00271,"percentile":0.1911,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.27%).
