Sensitive information disclosure in Microsoft Teams for iOS (versions 2.0.0 through prior to 8.8.1) enables unauthenticated network attackers to access protected data without any user interaction, as reflected in the CVSS:3.1 vector AV:N/AC:L/PR:N/UI:N with C:H. The vulnerability is rooted in CWE-200 improper information exposure and is iOS-platform-specific, confirmed by CPE cpe:2.3:a:microsoft:teams:*:*:*:*:*:iphone_os:*:*. No active exploitation is confirmed - the CVE is absent from the CISA KEV catalog, SSVC assessment rates exploitation as none, and EPSS sits at 0.68% (49th percentile), indicating low observed exploitation probability at time of analysis.
Path-traversal-driven remote code execution affects the Microsoft Teams client for Android in all builds prior to 1.0.0.2026133602, where improper restriction of pathnames (CWE-22) lets an unauthorized attacker escape the app's restricted directory and execute code over the network. Microsoft rates it CVSS 9.8, but real-world signals are muted: EPSS is 0.62% (47th percentile), CISA SSVC records exploitation status as 'none', and there is no public exploit identified at time of analysis. A vendor patch is available, making prompt client updates the decisive control.
Cross-site scripting in Microsoft Teams for Android (versions below 1.0.76.202611302) enables an authenticated attacker to inject and render malicious content within a target user's Teams client, achieving spoofing of interface elements or participants over the network. The scope-changed CVSS vector (S:C, C:H) indicates the vulnerability can expose data beyond the Teams application boundary - potentially including session tokens or cross-context information - when a victim views attacker-controlled content. No public exploit code has been identified and SSVC classifies exploitation as none, though the high confidentiality impact warrants prioritized patching for organizations reliant on Teams for sensitive communications.
Privilege elevation in Microsoft Teams lets a remote, unauthenticated attacker gain unauthorized access across a network due to a missing authorization check (CWE-862). The maximum 10.0 CVSS rating stems from a changed scope with high confidentiality and integrity impact, meaning the flaw reaches resources beyond the initially vulnerable component. No public exploit identified at time of analysis and the issue is not listed in CISA KEV, but the perfect-score, no-precondition profile makes it a top-tier patch priority.
Cryptographic signature spoofing in Microsoft Teams exposes enterprise collaboration environments to unauthenticated identity impersonation over the network. The flaw, tagged as a JWT attack enabling authentication bypass, allows a remote attacker with no prior credentials to forge or tamper with token-based identity claims that Teams fails to properly verify. No active exploitation has been confirmed by CISA KEV, and no public proof-of-concept has been identified at time of analysis, though the CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates a low-barrier, remotely exploitable path with high integrity impact.
Privilege elevation in Microsoft Teams allows an authenticated attacker with low-level access to bypass authentication controls and gain higher privileges across a network boundary. The CVSS:3.1 vector (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H) shows the flaw is remotely reachable, requires only low existing privileges, needs no user interaction, and crosses a security scope to compromise confidentiality and integrity of resources beyond the initially authorized context. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV, but the 9.6 base score reflects the low barrier to abuse once an attacker holds any authenticated Teams foothold.
Information disclosure in Microsoft Teams for Android allows an authenticated remote attacker to extract sensitive data via an injection flaw (CWE-74) in output passed to a downstream component. The CVSS 8.1 rating reflects high confidentiality and availability impact over the network with low privileges and no user interaction, though no public exploit identified at time of analysis and the vulnerability is not listed in CISA KEV.
Microsoft Teams contains an access control vulnerability that enables unauthenticated remote attackers to extract sensitive information without user interaction. The flaw affects Teams deployments and carries a high severity rating, though no patch is currently available. Exploitation requires only network access with no additional prerequisites, making this a significant risk for organizations using the platform.
