CVE-2026-57253 Foxit Software Inc. CVE debrief

Who should care

Users of Unknown Vendor products should review their inventory for potential exposure to this vulnerability and implement compensating controls to monitor and mitigate potential attacks. They should also verify vendor remediation and apply patches if available. Additionally, operators, platform administrators, vulnerability management teams, and security teams may be impacted and should review the CVE record and vendor guidance to determine the severity and potential impact on their environments.

Technical summary

The vulnerability occurs when an abnormal image object causes the renderer to enter the wrong processing branch. During scan line conversion, an invalid image buffer pointer is used, leading to an application crash. 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.
