CVE-2026-50063

Code execution via crafted PAR file parsing

Published Aug 11, 2026 · Updated Aug 11, 2026

Out-of-bounds read in Siemens Solid Edge SE2025 and SE2026 allows context-dependent attackers to execute code via a crafted PAR file. Siemens identifies PAR parsing as the locus but has not disclosed the affected routine or the exact bounds-check failure. Exploitation requires a user to open the file, after which code executes with the current process's privileges.
