CVE-2025-62453

Security feature bypass via unvalidated AI output

Published Nov 11, 2025 · Updated Nov 11, 2025

Improper output validation in Microsoft Visual Studio Code before 1.105.0 allows local users to bypass a security feature. Microsoft identifies generative AI output from GitHub Copilot as the untrusted input, but has not disclosed the affected code locus or the validation operation that fails. Exploitation requires low privileges and user interaction and can compromise integrity, with no reported confidentiality or availability impact.
