CVE-2026-18300 is an integer-overflow vulnerability in GEGL RGBE/HDR image-file parsing, affecting applications including GIMP that use the vulnerable component. Insufficient validation of attacker-controlled image data permits an integer overflow before buffer allocation. Processing a specially crafted HDR file can result in arbitrary code execution in the context of the affected application process.
