CVE-2026-24737Public exploitNetwork attack vector

Arbitrary JavaScript execution via unescaped AcroForm names

Published Feb 2, 2026 · Updated Feb 2, 2026

PDF object injection in Parallax jsPDF 4.0.0 and earlier allows remote attackers to execute JavaScript when a victim opens a generated PDF. AcroForm choice options and button appearance-state setters serialize leading-slash values as raw PDF Name objects instead of escaping delimiters. Exploitation requires an application to pass attacker-controlled values to an affected API and a victim to open the resulting PDF in a viewer that executes PDF JavaScript.
