CVE-2025-65875Network attack vector

Authenticated code execution via PHP font inclusion

Published Feb 3, 2026 · Updated Feb 3, 2026

PHP file inclusion in FPDF 1.86 and earlier allows remote authenticated users to execute code through AddFont(). AddFont() passes a caller-selected font-definition path to _loadfont(), which includes the PHP file as executable code instead of parsing inert font data. Exploitation requires an application to expose both a file-placement path and attacker control over the AddFont filename or directory.
