SCA: security update for pontedilana/php-weasyprint (GHSA-f5gc-qxf8-mh9g)

high Tenable Self-Hosted Container Security Plugin ID 444058

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 2.5.1,
 `pontedilana/php-weasyprint` builds the shell command for WeasyPrint by passing the binary path through
 `escapeshellarg()` first and then checking the *quoted* result with `is_executable()`. On POSIX
 `escapeshellarg('/usr/local/bin/weasyprint')` returns `'/usr/local/bin/weasyprint'` with the single-quote
 characters as part of the string, so `is_executable()` looks for a file whose actual name includes those
 quotes. That file never exists, the "safe" branch is dead code, and the raw `$binary` string (set via the
 constructor or `setBinary()`) flows directly into
 `Symfony\Component\Process\Process::fromShellCommandline()`. Any deployment whose binary path is sourced
 from configuration, an environment variable, or a per-tenant setting reaches a shell-command-injection
 sink. The library is documented as a one-to-one substitute for KnpLabs/snappy and inherited the exact pre-
 fix codepath KnpLabs patched in GHSA-vpr4-p6fq-85jc. PhpWeasyPrint version 2.5.1 contains a patch for the
 issue. (CVE-2026-49260)

Solution

Update the pontedilana/php-weasyprint library and its related packages to version 2.5.1 or later.
