Windows shell spoofing vulnerability puts sensitive data at risk

Erik Avakian, a technical counselor at Info-Tech Research Group, discussed the patching deadlines set by the Cybersecurity and Infrastructure Security Agency (CISA) under Binding Operational Directive (BOD) 22-01, which requires U.S. federal agencies to address vulnerabilities within 14 to 21 days. CISA can expedite patching to as little as three days for high-risk exploits. The vulnerability CVE-2026-32202, rated 4.3 on the Common Vulnerability Scoring System (CVSS), was actively exploited but did not qualify for an urgent patch cycle, resulting in a 14-day deadline. Avakian noted the debate over whether this timeframe is sufficient, suggesting that Microsoft’s rating and other factors influenced the decision not to escalate to an emergency directive requiring a 48 to 72-hour response.

CISA flags Windows Task Host vulnerability as exploited in attacks

The Cybersecurity and Infrastructure Security Agency (CISA) has issued a warning about a vulnerability in the Windows Task Host, identified as CVE-2025-60710, which poses a risk of privilege escalation, potentially allowing attackers to gain SYSTEM privileges. This flaw affects devices running Windows 11 and Windows Server 2025 and arises from a weakness in link following. Microsoft released a patch for this issue in November 2025. CISA has added CVE-2025-60710 to its list of actively exploited vulnerabilities and mandated that Federal Civilian Executive Branch agencies secure their systems within two weeks. CISA encourages all organizations, including those in the private sector, to implement necessary patches and improve network security. CISA also advised organizations to follow vendor instructions for mitigations or discontinue use of the affected product if mitigations are unavailable.

Your BitLocker-secured Windows PC isn’t so secure after all – unless you do this

Microsoft's BitLocker encrypts personal files on Windows hard drives to protect against unauthorized access in case of loss or theft. The BitLocker recovery key is essential for decrypting data, but Microsoft has confirmed it will comply with valid legal requests for access to these keys if they are stored in the cloud. This was highlighted during an FBI investigation in Guam, where Microsoft provided recovery keys related to a COVID unemployment fraud case. Microsoft receives about 20 requests for BitLocker keys annually, but many cannot be fulfilled if users do not store their keys in the cloud. The Guam case is the first known instance of Microsoft providing encryption keys to law enforcement, contrasting with a previous request from the FBI in 2013 that was declined. Users can choose to store their keys locally or in Microsoft's cloud, but storing them in the cloud carries risks of unauthorized access. For optimal security, it is recommended to save the recovery key on a USB stick or external drive, encrypting the file if necessary, and avoiding cloud storage. Users should check their BitLocker settings in Windows 11 or 10 to manage their recovery keys and consider removing any keys stored in the cloud.

Windows info-disclosure 0-day bug gets a fix as CISA sounds alarm

Microsoft and the U.S. government have issued a warning about a vulnerability in Windows, designated CVE-2026-20805, which is currently being exploited. This flaw allows an authorized attacker to leak a memory address from a remote ALPC port, potentially leading to arbitrary code execution. It has a medium severity rating of 5.5 on the CVSS scale. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added this vulnerability to its Known Exploited Vulnerabilities catalog and requires federal agencies to implement a patch by February 3. Additionally, two other vulnerabilities were acknowledged: CVE-2026-21265, a secure boot certificate expiration bypass with a CVSS rating of 6.4, and CVE-2023-31096, an elevation of privilege flaw affecting third-party Agere Modem drivers, rated at 7.8. Two more vulnerabilities, CVE-2026-20952 (CVSS 7.7) and CVE-2026-20953 (CVSS 7.4), are use-after-free flaws in Office that could allow unauthorized code execution.
