CVE-2026-33893 · Severity: high · CVSS 7.5 · Published 2026-05-12

Siemens Teamcenter, a product lifecycle management (PLM) system used to manage industrial design and manufacturing processes, contains a security flaw where sensitive keys are hardcoded into the software. An attacker could extract these keys to bypass security measures and gain unauthorized access to the system. This could lead to the exposure of proprietary engineering data or disruption of manufacturing workflows.

Technologies: Siemens Teamcenter. Vendors: Siemens.

Technical details

The vulnerability (CWE-798) exists because Siemens Teamcenter stores hardcoded keys directly within the application code for obfuscation purposes. A remote, unauthenticated attacker can extract these keys from the application binaries or configuration. Once obtained, these keys can be misused to bypass security controls or decrypt sensitive data, leading to unauthorized access. The issue affects multiple versions of Teamcenter, and Siemens has released patches (e.g., V2312.0014, V2406.0012) to remediate the flaw.
