🔧 Microsoft has released out-of-band updates for Windows 10, Windows 11, and Windows Server to address an issue that caused Outlook to freeze when opening PST files stored in cloud-backed storage such as OneDrive or Dropbox. The problem emerged after the January 13, 2026 Patch Tuesday updates and mainly affected classic Outlook configurations used in enterprises. Affected instances could become unresponsive until the process was terminated or the system restarted, and users reported missing Sent Items and duplicate downloads. The fixes are available via Windows Update or the Microsoft Download Catalog and include several KB updates for specific Windows and Server versions.

⚠️ A coordinated campaign is exploiting a critical authentication-bypass flaw in the GNU InetUtils telnetd server, tracked as CVE-2026-24061. The bug, present since 2015, lets attackers set the USER environment variable (for example USER=-f root) to bypass /usr/bin/login and obtain a root shell. Patches are in InetUtils 2.8; mitigations include disabling telnetd or blocking TCP port 23. GreyNoise observed limited, mostly automated exploitation activity and recommends immediate patching and hardening.

⚠️ Cisco has released patches for a critical remote code execution vulnerability, CVE-2026-20045, affecting Unified Communications Manager, Unity Connection, and Webex Calling Dedicated Instance. The flaw allows unauthenticated remote attackers to gain user access via crafted HTTP requests and then escalate privileges to root without user interaction. No workarounds exist; fixes are version-specific and organizations should apply the matching patch or migrate unsupported 12.5 systems.

⚠️ The Cybersecurity and Infrastructure Security Agency (CISA) warns of a stack-based buffer overflow in Johnson Controls' iSTAR Configuration Utility (ICU), tracked as CVE-2025-26386. The vulnerability affects ICU versions <= 6.9.7 and, under certain conditions, could lead to an operating system failure on the host machine. Johnson Controls released a vendor fix; update ICU to version 6.9.8. CISA recommends applying the update promptly and following network-segmentation and remote-access best practices to reduce exposure.

🛡️ Oracle's January quarterly update delivers 337 security fixes across its product portfolio, including 27 rated critical. The vendor reports no known in-the-wild exploitation at release, but urges priority attention to the 13 CVEs mapped to critical severity. A substantial share of patches address third-party and open-source components such as Apache Tika, creating cross-product CVE overlap and assessment complexity.

🔒 Zoom and GitLab released security updates to address multiple vulnerabilities that could enable denial-of-service, remote code execution, and a two-factor authentication bypass. The most severe is a critical command injection in Zoom Node Multimedia Routers (CVE-2026-22844, CVSS 9.9) that may allow remote code execution; Zoom reports no evidence of active exploitation. GitLab patched several high-severity DoS and 2FA-bypass issues across CE and EE releases. Administrators should apply the provided patches, upgrade affected modules, and review exposure to untrusted networks immediately.

🛡️ The CERT/CC has warned of a code-injection vulnerability in the binary-parser npm library (CVE-2026-1245) that can permit execution of arbitrary JavaScript when parser source is dynamically generated at runtime. The flaw arises from unsanitized, attacker-controlled values — such as parser field names and encoding parameters — being embedded into code compiled with the Function constructor. Applications that accept untrusted parser definitions are at risk; static, hard-coded parsers are not affected. Users should upgrade to binary-parser 2.3.0 and avoid passing user-controlled values into parser definitions.

⚠️ A critical vulnerability in ACF Extended (CVE-2025-14533) allows unauthenticated attackers to obtain administrative privileges by abusing the plugin's 'Insert User / Update User' form action in versions up to 0.9.2.1. The flaw fails to enforce role restrictions at the form level, enabling attackers to set arbitrary roles, including administrator, when a role field is present. The vendor released a patch in version 0.9.2.2 on December 14, 2025; administrators should update immediately and audit any forms that create or update users because roughly 50,000 sites may still be exposed.

🔒 Chainlit, a widely used framework for building conversational AI applications, contained two server-side vulnerabilities (CVE-2026-22218 and CVE-2026-22219) that allow authenticated users to read arbitrary files and trigger SSRF in affected deployments. The flaws stem from insufficient validation of user-controlled properties in custom elements and SQLAlchemy-backed storage. Combined, they can expose environment variables, cached prompts, API keys and cloud metadata, enabling lateral movement beyond the app layer. Chainlit released 2.9.4 on 24 December 2025 and users are advised to apply the patch immediately; temporary WAF signatures were published as mitigation.

🛡️ Amazon announced quarterly security and critical updates for Amazon Corretto LTS distributions on January 20, 2026.

Customers can obtain releases from the Corretto home page or configure Apt, Yum, or Apk repositories on Linux to receive updates. Feedback and issue reports are invited via the Corretto GitHub repository.

🔒 Rockwell Automation reported two high-severity vulnerabilities in Verve Asset Manager affecting legacy components: the ADI server and the Ansible playbook. Both issues can result in unencrypted sensitive information being stored in environment variables or during playbook execution and are rated CVSS 7.2 and 7.9. Rockwell states the flaws are resolved in 1.42; organizations should upgrade and contact Rockwell TechConnect for assistance. CISA also recommends minimizing network exposure and using secure remote access such as up-to-date VPNs.

⚠️ Schneider Electric warns that multiple vulnerabilities in the CODESYS Runtime System V3 communication server affect many Schneider products and third-party devices embedding CODESYS. Exploitable issues include denial-of-service and, in some configurations, remote code execution; several CVEs carry CVSS scores up to 8.8. Schneider has published patches and mitigations for many affected product families; operators should apply vendor updates and follow immediate network and access controls to reduce exposure.

⚠️ Microsoft is enforcing new Intune MAM security requirements beginning January 19 (or shortly after), requiring updated iOS SDKs/wrappers and an updated Android Company Portal to keep apps running. Enterprises that don’t update wrapped or SDK-integrated apps — including Outlook and Teams — risk having those apps blocked from launching. Admins should rebuild or rewrap affected apps, push updates, enable conditional launch policies, and monitor App Protection Status to avoid user outages.

🔧 Microsoft has issued out-of-band Windows updates to address two issues introduced by the January 2026 security updates: credential prompt failures that can block Microsoft 365 Cloud PC and remote desktop sign-ins, and a shutdown/hibernate failure on Windows 11 23H2 when Secure Launch is enabled. The fix packages must be manually downloaded from the Microsoft Update Catalog, and administrators can deploy Known Issue Rollback (KIR) installers via Group Policy for enterprise-managed devices when immediate deployment is required.

⚠️ Cisco has released patches for a critical zero-day, CVE-2025-20393, in AsyncOS that affects Secure Email Gateway (SEG) and Secure Email and Web Manager (SEWM) appliances. The flaw allows a remote attacker to gain root by sending a crafted HTTP request to the Spam Quarantine interface when it is enabled and reachable from the internet. Cisco first learned of exploitation in December, issued a public advisory on Dec. 17, and has now published fixes to address the issue.

🔓 Modular DS versions 2.5.1 and earlier contain a critical privilege-escalation bug (CVE-2026-23550) that lets unauthenticated attackers gain full WordPress admin access by calling unprotected API routes under /api/modular-connector/. Patchstack reported active exploitation and the vendor released Modular DS 2.5.2 on January 14, 2026. Administrators should update immediately, check for rogue admin accounts, enable two-factor authentication, apply IP restrictions, and consider Patchstack’s mitigation rules if immediate patching isn’t possible.

⚠️ Check Point Research links the Linux-based RondoDox botnet to a coordinated exploitation campaign against HPE OneView, leveraging the critical RCE flaw CVE-2025-37164.
