CVE-2026-49260 (opens in a new tab)How to fix?
Upgrade pontedilana/php-weasyprint to version 2.5.1 or higher.
Overview
pontedilana/php-weasyprint is a PHP library allowing PDF generation from an url or a html page.
Affected versions of this package are vulnerable to Command Injection in the binary-path validation in src/AbstractGenerator.php, where is_executable() is tested against the escapeshellarg()-quoted path rather than the raw one. A user who can control the binary path passed to the Pdf constructor or AbstractGenerator::setBinary() can execute arbitrary commands as the PHP process user by embedding shell metacharacters in that value. Exploitation requires influence over the binary path, via configuration, environment variables, an admin UI, or per-tenant settings. And the injected commands run with the privileges of the PHP process.
