CVE-2026-57241 Foxit Software Inc. CVE debrief

Who should care

Users of applications that process PDFs with JavaScript should be aware of this vulnerability. Although details about affected products are limited, the CVE record indicates a MEDIUM CVSS score of 6.1.

Technical summary

The vulnerability occurs when the application processes a PDF file containing JavaScript. As JavaScript performs operations on the page and document, it causes page-related objects within the application to lose synchronization. Despite this, the renderer continues to trust the outdated page count, ultimately leading to an application crash due to out-of-bounds access. The CVSS vector for this vulnerability is CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H.

Defensive priority

Apply patches or updates from the vendor as soon as available. In the meantime, consider disabling JavaScript execution in PDF files or restricting access to untrusted PDF sources.

Recommended defensive actions

• Apply patches or updates from the vendor as soon as available.
• Consider disabling JavaScript execution in PDF files if not necessary.
• Restrict access to untrusted PDF sources.
• Monitor the application for unusual crashes or behavior.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
