SCA: security update for dompdf/dompdf (GHSA-j8qw-6jw8-r297)

medium Tenable Self-Hosted Container Security Plugin ID 445185

Description

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

 - Dompdf is an HTML to PDF converter for PHP. In versions 3.15 and prior, if a malicious actor can supply
 unrestricted content for rendering by Dompdf they can utilize the SVG rendering functionality to leak
 filesystem information when rendering PDF files using image references within a data-URI encoded SVG
 document. Using an <image> element inside a data-URI embedded SVG, an attacker can attempt to embed other
 files via the href or xlink:href attributes. When processing a file that does not exist (e.g.
 file:///DOESNOTEXIST), dompdf behaves differently than it does when accessing a file or directory that
 actually exists on the filesystem. This issue has been fixed in version 3.16. (CVE-2026-59943)

Solution

Update the dompdf/dompdf library and its related packages to version 3.1.6 or later.
