SCA: security update for github.com/gotenberg/gotenberg/v8 (GHSA-7v3r-m9c8-r855)

high Tenable Cloud Security Plugin ID 446844

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.30.0, The ExifTool metadata write
 blocklist in Gotenberg can be bypassed using ExifTool's group-prefix syntax, enabling arbitrary file
 rename, move, hardlink, and symlink creation on the server. ExifTool supports group-prefix syntax where
 File:FileName is processed identically to FileName -- the prefix is stripped by SetNewValue in Writer.pl
 before tag matching. The safeKeyPattern regex (^[a-zA-Z0-9\-_.:]+$) allows colons, so prefixed tag names
 pass validation. Any prefix works: File:FileName, System:Directory, a:HardLink, etc. Additionally,
 FilePermissions, FileUserID, and FileGroupID pseudo-tags are not blocked at all and can modify file
 attributes without any prefix. This vulnerability is fixed in 8.30.0. (CVE-2026-42590)
