CVE-2026-65769Network attack vector

Unauthorized disclosure of sensitive information

Published Aug 11, 2026 · Updated Aug 25, 2026

Information disclosure in Microsoft Teams for iOS before 8.14.1 allows remote attackers to read sensitive information via unspecified vectors. Microsoft has not published the affected code path or the incorrect operation on untrusted input, and the public CVE, NVD, and GitHub advisory records disclose no mechanism beyond sensitive data exposure. No privileges are required; Microsoft scores user interaction as required, while NVD scores none, so triage should focus on iOS Teams workflows that can expose confidential data over the network.
