CVE-2020-13449Public exploitNetwork attack vector

Unauthenticated container file read via path traversal

Published Jan 7, 2021 · Updated Aug 4, 2024

Path traversal in Gotenberg's Markdown engine through 6.2.1 allows remote attackers to read arbitrary files from the container. Public records identify the Markdown engine as the locus but do not disclose the affected function, request field, or path-validation operation. Any unauthenticated caller who can reach the PDF conversion API can obtain file contents accessible to the container process, with no reported write capability through this flaw.
