Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
GHSA-62p3-hvxx-fxg4: Gotenberg versions up to and including 8.30.1 (github.com/gotenberg/gotenberg/v8) block some ExifTool tag names, but a group-prefixed form such as System:FileName is not blocked, so ExifTool still renames or moves files. Any client that can send HTTP requests to the service can do this without logging in, and the advisory describes changing file permissions the same way. No fixed version is listed; the source gives no workaround beyond restricting access to the service.
