CWE-190Published: April 11, 2026· Updated: Apr 14, 2026

7.8

CVSS v3.1

Official Description

GIMP PSD File Parsing Integer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the parsing of PSD files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28807.

Technical Analysis

CVE-2026-4150 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.

A proof-of-concept (PoC) exploit exists for CVE-2026-4150. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
