CVE-2026-2050 GIMP CVE debrief

Who should care

Organizations and individuals using GIMP, especially those handling HDR files from untrusted sources, should prioritize patching this vulnerability. Given the HIGH CVSS score of 7.8, this vulnerability poses a significant risk. Users of GIMP should ensure they are running a version that has addressed this issue to prevent potential code execution.

Technical summary

The vulnerability exists within the HDR file parsing functionality of GIMP. Specifically, it results from inadequate validation of user-supplied data length before it is copied to a heap-based buffer. This oversight allows remote attackers to execute arbitrary code on affected GIMP installations. The attack requires user interaction, such as visiting a malicious page or opening a malicious file. The CVSS vector is CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, indicating Local attack vector, Low attack complexity, No privileges required, and User interaction required.

Defensive priority

High. Immediate patching is recommended due to the HIGH CVSS severity and the potential for remote code execution.

Recommended defensive actions

• Apply the official patch or update provided by GIMP to address the HDR file parsing vulnerability.
• Restrict the opening of HDR files from untrusted sources until the patch is applied.
• Implement additional monitoring for suspicious HDR file handling activities.
• Ensure user education on the risks of opening files from untrusted sources.
• Consider implementing compensating controls such as file type restrictions or additional security layers for HDR file processing.
