CVE-2026-59091
HIGH 7.3A flaw was found in GIMP's file format plugins, including those for PSD and PAA files. A remote attacker could exploit these vulnerabilities by tricking a user into opening a specially crafted image file. This could lead to unexpected application behavior or other potential security impacts without requiring further user interaction.
Severe if exploited (CVSS 7.3), but no known exploitation and low modeled probability. Patch on a normal cadence.
