{"id":"CVE-2026-110734","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-110734","generatedAt":"2026-10-28T04:35:46.372Z","title":"Godot Engine through 4.7.2 has a heap out-of-bounds write in the Radiance HDR (.hdr) image decoder (modules/hdr/image_loader_hdr.cpp).","description":"Godot Engine through 4.7.2 has a heap out-of-bounds write in the Radiance HDR (.hdr) image decoder (modules/hdr/image_loader_hdr.cpp). The run-length decoding loop expands RLE instructions read from the file into a buffer sized from the image dimensions, without validating that an instruction's repeat/copy count fits the remaining capacity of the row buffer. A crafted .hdr file therefore writes attacker-supplied bytes past the end of the heap allocation, with the overflow length and content controlled by the file. The defect is reached automatically when the product imports a crafted .hdr (e.g., when opening a project containing one), and at runtime in exported projects that load untrusted .hdr images. NOTE: the Supplier's position is that the research has identified \"no security issues\" because the required attacker access is outside of the current Godot Engine threat model.","published":"2026-10-14T16:17:44.000Z","lastModified":"2026-10-24T01:17:07.000Z","status":"Awaiting Analysis","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":2.5,"severity":"LOW","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N"},"cwe":["CWE-787"],"affected":[],"epss":{"score":0.00156,"percentile":0.04734,"date":"2026-10-27","history":[{"date":"2026-10-15","score":0.00134,"percentile":0.02537}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.16%).
