The most severe, CVE-2026-92370, is a remote session access control bypass that could enable remote code execution. The other four flaws—path traversal, heap-based buffer overflow, a TOCTOU race condition, and improper path validation—could let local attackers escalate privileges to SYSTEM or root. No public exploit code or active exploitation has been observed. TeamViewer recommends updating to version 15.82, which resolves all five issues across supported maintenance and legacy releases. ## Full article daily.dev links to this article rather than hosting it.
