Security control bypass via undisclosed mechanism
Published Jun 30, 2023 · Updated Jan 1, 2025
Security feature bypass in Microsoft Edge (Chromium-based) before 91.0.864.59 allows remote attackers to bypass a control after user interaction. Microsoft has not published the affected component or the operation that mishandles untrusted content, so the bypass mechanism remains undisclosed. The published assessment limits consequences to low confidentiality and integrity impact without service interruption.
