CVE-2024-25117Public exploit

Code execution via unchecked SVG font path

Published Feb 21, 2024 · Updated Aug 28, 2024

Path validation failure in dompdf php-svg-lib before 0.5.2 allows attackers to trigger PHAR deserialization via crafted SVG font-family values. Style::fromAttributes() and Style::parseCssStyle() accept inline or attribute font-family values and pass a phar:// path as fontName to downstream font handling without validating the scheme or external-reference policy. Code execution requires PHP before 8.0 and a consuming library that accepts attacker-controlled SVG input without revalidating fontName; other consumers can suffer restriction bypass or server-side request forgery.
