A string length is read from the resource file into a signed 32-bit integer and compared against the destination buffer size with a signed comparison, which conditionally resizes the buffer. A negative length value skips the resize; the same value is then passed to the copy routine as an unsigned byte count, where it sign-extends to a huge value, copying file-controlled data far past the undersized heap allocation.

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.","publishedAt":"2026-10-14T15:41:50.110Z","updatedAt":"2026-10-20T01:36:20.303Z","severity":{"score":2.5,"label":"Low","version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N","source":"mitre"},"assigner":"mitre","products":["godotengine Godot Engine"],"affected":[{"vendor":"godotengine","product":"Godot Engine","defaultStatus":"unknown","versions":[{"version":"1.0.0","status":"affected","lessThanOrEqual":"4.7.2","versionType":"semver"}],"modules":["Binary resource loader"],"programFiles":["core/io/resource_format_binary.cpp"],"programRoutines":[{"name":"ResourceLoaderBinary::get_unicode_string"}],"repo":"https://github.com/godotengine/godot"}],"references":["https://github.com/godotengine/godot/issues/123608","https://axeghost.offprint.app/a/3mvs6zo4blo23-three-memory-safety-bugs-in-godots-untrusted-file-parsers","http://www.openwall.com/lists/oss-security/2026/10/15/3"],"weaknesses":["CWE-195"],"ingestedAt":"2026-10-29T20:10:33.477Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/110xxx/CVE-2026-110735.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-110735","state":"PUBLISHED","datePublished":"2026-10-14T15:41:50.110Z","dateUpdated":"2026-10-20T01:36:20.303Z","assignerShortName":"mitre","assignerOrgId":"8254265b-2729-46b6-b9e3-3dfca2d5bfca","dateReserved":"2026-10-14T15:41:49.785Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"Godot Engine through 4.7.2 has a heap out-of-bounds write in the binary resource loader (core/io/resource_format_binary.cpp, ResourceLoaderBinary::get_unicode_string).
