CVE-2026-57244 Foxit Software Inc. CVE debrief

Who should care

Organizations using the affected product should prioritize patching to prevent potential crashes and ensure application stability. This involves reviewing system inventories to identify potential exposure, implementing compensating controls to monitor application stability, and handling potential crashes. Additionally, organizations should conduct thorough inventory checks to identify and update affected systems with vendor-supported updates or mitigations through normal change control where exposure is confirmed.

Technical summary

The vulnerability occurs when the synchronization process fails to protect against re-entry and verify object lifecycles after a JavaScript form reset. This leads to a control pointer failure, causing the application to crash as it continues to dereference the failed pointer. The issue is associated with CWE-416. The lack of specific details on affected products or components necessitates a cautious approach to ensure comprehensive coverage of potential exposures. Affected product or component details are not specified; therefore, a thorough review of system inventories is necessary to identify potential exposure. The vulnerability's classification as HIGH severity underscores the importance of prompt mitigation to prevent potential service disruptions.

Defensive priority

High priority due to potential for application crashes and impact on service availability. Organizations should implement compensating controls to monitor application stability and handle potential crashes, and conduct thorough inventory checks to identify and update affected systems with vendor-supported updates or mitigations through normal change control where exposure is confirmed. Review relevant monitoring, detection, and logs for exposed assets that need extra review and track exceptions, retest remediated assets, and close the item only after evidence is documented. 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. Check for additional information on the vulnerability from reliable sources and assess the vulnerability's impact and scope based on available evidence. The synchronization process lacks re-entry protection and object lifecycle verification, resulting in the failure of the control pointer during the traversal process. The control pointer failure causes the application to crash as it continues to dereference the failed pointer. This type of vulnerability can have significant operational impacts and should be addressed promptly to prevent potential service disruptions. Affected product or component details are not specified; therefore, a thorough review of system inventories is necessary to identify potential exposure. The vulnerability's classification as HIGH severity underscores the importance of prompt mitigation to prevent potential service disruptions. The lack of specific details on affected products or components necessitates a cautious approach to ensure comprehensive coverage of potential exposures. The implementation of compensating controls and thorough inventory checks are crucial steps in managing the risk associated with this vulnerability. The recommended actions include applying patches or updates provided by the vendor, implementing compensating controls, and conducting thorough inventory checks to identify and update affected systems. Additionally, reviewing

Recommended defensive actions

• Apply patches or updates provided by the vendor to address the vulnerability.
• Implement compensating controls to monitor application stability and handle potential crashes.
• Conduct thorough inventory checks to identify and update affected systems.
• 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.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.

Evidence notes

Evidence is limited; primary records indicate a high-severity vulnerability with a CVSS score of 7.8. Further details are needed to fully assess the vulnerability's impact and scope. The synchronization process lacks re-entry protection and object lifecycle verification, resulting in the failure of the control pointer during the traversal process. The control pointer failure causes the application to crash as it continues to dereference the failed pointer.
