## Technical details

CVE-2026-59701 is an out-of-bounds read vulnerability (CWE-125) in Simcenter Femap's BMP file parsing logic. The vulnerability is triggered when the application processes specially crafted BMP files, allowing an attacker to read memory beyond allocated boundaries. Attack vector is local with user interaction required—a victim must be tricked into opening a malicious BMP file. Successful exploitation can lead to arbitrary code execution in the context of the Femap process. The patch is available: update to version V2606.0001 or later.
