{"schemaVersion":3,"id":"CVE-2026-110734","aliases":["DEBIAN-CVE-2026-110734","UBUNTU-CVE-2026-110734"],"status":"published","duplicateOf":null,"title":null,"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.","dates":{"published":"2026-10-14T15:36:08.839Z","modified":"2026-10-15T16:08:05.368Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":2.5,"severity":"low","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","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","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","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","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV
