Sensitive information disclosure through undisclosed mechanism
Published Aug 21, 2023 · Updated Aug 10, 2026
Information disclosure in Microsoft Edge (Chromium-based) before 116.0.1938.54 allows remote attackers to read sensitive data. Microsoft has not published the affected component or the operation that exposes protected information to attacker-controlled content. Exploitation requires user interaction and high-complexity conditions, and the published impact is limited to reading information.
