CVE-2026-58113 is a high-severity cross-site scripting vulnerability in Siemens Teamcenter V2412, published on 8 Sep 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
A vulnerability has been identified in Teamcenter V2412 (All versions < V2412.0013), Teamcenter V2506 (All versions < V2506.0010), Teamcenter V2512 (All versions < V2512.2607), Teamcenter V2606 (All versions < V2606.2607).
