{"id":"CVE-2026-110734","published":"2026-10-14T16:17:44.320","lastModified":"2026-10-16T19:55:59.740","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.","cvssScore":2.5,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N","cwes":["CWE-787"],"vendors":[],"products":[],"references":[{"url":"https://axeghost.offprint.app/a/3mvs6zo4blo23-three-memory-safety-bugs-in-godots-untrusted-file-parsers","tags":[]},{"url":"https://github.com/godotengine/godot/issues/123608","tags":[]},{"url":"http://www.openwall.com/lists/oss-security/2026/10/15/4","tags":[]}],"exploitRefs":[{"url":"https://github.com/godotengine/godot/issues/123608","tags":[]}],"hasPoc":true,"ai":null}
