CVE-2026-24737
Description
A flaw was found in jsPDF, a JavaScript library for generating PDFs. A remote attacker could exploit this vulnerability by providing unsanitized input to specific methods within the Acroform module, such as AcroformChoiceField.addOption or AcroFormCheckBox.appearanceState. This allows the attacker to inject arbitrary PDF objects, including JavaScript actions, which are then executed when a victim opens the crafted PDF document, leading to arbitrary code execution.
Statement
This IMPORTANT vulnerability in jsPDF affects Red Hat Advanced Cluster Security (RHACS) where it could allow arbitrary JavaScript execution. The flaw occurs if an attacker provides a specially crafted PDF document containing injected JavaScript actions, and a victim subsequently opens this malicious document. Exploitation requires user interaction with a malicious file.
Mitigation
To mitigate this vulnerability, avoid processing untrusted or unverified PDF documents with applications utilizing the jsPDF library. Ensure that any input provided to jsPDF's AcroForm methods and properties is properly sanitized to prevent the injection of arbitrary PDF objects and JavaScript actions. This operational control reduces the risk of arbitrary JavaScript execution.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
