CVE-2025-61839

Code execution via unvalidated usdGltf buffer read

Published Nov 11, 2025 · Updated Nov 11, 2025

Out-of-bounds read in Adobe Format Plugins 1.1.1 and earlier allows remote attackers to execute code through a crafted glTF file. The usdGltf plugin fails to validate user-supplied file data before reading an allocated buffer, causing a read beyond its end. Exploitation requires interaction with the USD library, typically a victim opening the malicious file, and code runs in the current process context.
