Insertion of sensitive information into sent data in Microsoft Teams for Android allows an authorized attacker to disclose information over a network.
AnalysisAI
Microsoft Teams for Android before build 1416/1.0.0.2026133602 inserts sensitive information into outbound network transmissions (CWE-201), enabling a low-privileged authenticated attacker to intercept and read confidential data over the network when a victim user performs an in-app action. The CVSS scope change (S:C) with high confidentiality impact (C:H) signals that the leaked data can cross trust boundaries beyond the attacker's own session, potentially exposing other users' or sessions' sensitive material. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires: (1) the attacker holds or controls a low-privilege Microsoft Teams account (PR:L - unauthenticated exploitation is not supported by the CVSS vector); (2) a victim user performs a specific in-app action in Teams for Android (UI:R - the exact triggering action is not described in available data and must be inferred from the full MSRC advisory); (3) the attacker is network-positioned to intercept the outbound transmission, e.g., via a shared Wi-Fi network, corporate proxy, or local certificate pinning bypass. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 6.8 (Medium) is calibrated by the conflicting signals of broad network exploitability (AV:N/AC:L) against the authentication barrier (PR:L) and required user interaction (UI:R). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update Microsoft Teams for Android to build 1416/1.0.0.2026133602 or later, available via the Google Play Store automatic update mechanism or through enterprise mobile device management (MDM) push via Microsoft Intune or equivalent platforms. … Detailed patch versions, workarounds, and compensating controls in full report. |
