CVE-2026-48372

Code execution via unvalidated glTF accessor types

Published Jul 28, 2026 · Updated Jul 28, 2026

Heap-based buffer overflow in Adobe Format Plugins 2026.05 and earlier allows attackers to execute code via a crafted glTF file. The usdgltf importer accepts incompatible vertex-attribute accessor types and uses the resulting layout to process mesh data beyond a heap allocation. Exploitation requires a victim to open the file, after which code runs with the victim’s current-user privileges.
