CVE-2026-90947

Name of the Vulnerable Software and Affected Versions GIMP (affected versions not specified)

Description A flaw in the Lighting Effects filter occurs when processing a specially crafted lighting preset file. The filter fails to properly validate the number of light sources, leading to an out-of-bounds write, which is a condition where data is written outside the intended memory boundary, resulting in memory corruption. This could allow an attacker to cause a crash or achieve arbitrary code execution by convincing a user to open a malicious preset file.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
