SCA: security update for pontedilana/php-weasyprint (GHSA-2fmj-p74r-3wjm)

high Tenable Self-Hosted Container Security Plugin ID 444053

Description

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

 - PhpWeasyPrint is a PHP library allowing PDF generation from a URL or an HTML page. Prior to version 2.6.0,
 `pontedilana/php-weasyprint` guarded the output filename against the `phar://` stream wrapper with a case-
 sensitive blacklist. PHP stream wrappers are case-insensitive, so `PHAR://`, `Phar://`, etc. bypass the
 check and reach `fileExists()` (`file_exists()`) in `prepareOutput()`. On PHP 7 (which the library still
 supports — PHP 7.4+), this triggers deserialization of a crafted PHAR archive's metadata, leading to
 remote code execution. This is the patch-bypass of CVE-2023-28115. The same issue and fix were handled
 upstream in KnpLabs/snappy (GHSA-92rv-4j2h-8mjj). PhpWeasyPrint version 2.6.0 contains a patch for the
 issue. (CVE-2026-49286)

Solution

Update the pontedilana/php-weasyprint library and its related packages to version 2.6.0 or later.
