CVE-2026-0874

Code execution via malformed CATPART parsing

Published Feb 18, 2026 · Updated Feb 18, 2026

Out-of-bounds write in Autodesk Shared Components 2026.5 and earlier allows attackers to execute code via a crafted CATPART file. Autodesk has not identified the parser routine or disclosed how CATPART data drives the write beyond its intended memory boundary. Opening the file in a dependent Autodesk desktop product is required; successful exploitation runs code in that product's process, while failed attempts can crash it or corrupt data.
