Microsoft Teams for Android Vulnerability Exposes Sensitive Information
Microsoft patched CVE-2026-65812 in Teams for Android, an information-disclosure flaw that can leak credentials under specific conditions.
Microsoft fixed CVE-2026-65812, rated Important, which can insert sensitive information such as credentials into data sent by Microsoft Teams for Android (build 1416/1.0.0.2026133602). Exploitation is remote and low-complexity, requires low privileges plus user interaction, and impact is limited to high confidentiality impact. Microsoft says exploitation is less likely, with no public PoC, disclosure, or in-the-wild exploitation; the fix ships via the Teams app update on Google Play. Ofek Levin of Enclave reported the flaw through coordinated vulnerability disclosure.

New Windows Defender ShieldCrash 0-Day Bypasses Microsoft Patch to Read Files as SYSTEM
Researcher's ShieldCrash PoC claims Microsoft Defender still allows arbitrary file reads as SYSTEM on patched Windows, bypassing the CVE-2026-69414 fix.
Researcher MSNightmare released the ShieldCrash proof of concept showing Microsoft Defender can allegedly be made to read arbitrary files with SYSTEM privileges on fully patched Windows systems, bypassing the September 2026 fix for ShieldBreak (CVE-2026-69414). Microsoft has not confirmed the bypass, and the new flaw has no CVE assignment yet. The PoC repository contains C++ project files, a Warden.dll library, and an EICAR test archive, suggesting interaction with Defender's malware-detection and file-handling workflow. Reading files as SYSTEM could expose configuration files, credentials, private keys, and other users' data, though it does not enable code execution.
