Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
GHSA-2mrg-35hw-x3x9: Gotenberg versions before 8.34.0 are affected, and the advisory reports the issue in v8.33.0 under the default configuration. An attacker who can upload a crafted DOCX file to the LibreOffice conversion endpoint can cause the server to make outbound HTTP(S) requests to attacker-chosen destinations, and can also make it embed local image files into the output. Upgrade to Gotenberg 8.34.0 or later. The source gives no workaround.
