⚠️Microsoft has issued a fix for a known bug that caused File Explorer to briefly flash white when launched or navigated in dark mode after installing the optional KB5070311 update. The behavior also occurred when opening a new tab, toggling the Details pane, selecting 'More details' during file copy, or moving to/from Home or Gallery. Microsoft says the December cumulative KB5072033 update resolves the issue and includes related stability and PowerShell warnings.

🔔 Google has issued emergency updates for Chrome to address a zero-day tracked as Chromium bug 466192044 that is actively exploited in the wild. The vulnerability is a buffer overflow in the LibANGLE Metal renderer caused by improper buffer sizing and can lead to memory corruption, crashes, sensitive data leaks, or arbitrary code execution. Stable channel builds rolling out are Windows 143.0.7499.109, macOS 143.0.7499.110, and Linux 143.0.7499.109; users should update immediately or allow Chrome to install the update on restart.

🔐 Google released Chrome security updates addressing three vulnerabilities, including a high-severity flaw that is being actively exploited in the wild and is tracked as Chromium issue 466192044. Google withheld the CVE identifier, affected component, and technical details while coordinating disclosure to allow broader patching. The release also corrects two medium-severity issues in the Password Manager and Toolbar. Users should update to Chrome 143.0.7499.109/.110 (Windows/macOS) or 143.0.7499.109 (Linux) and apply vendor patches for other Chromium-based browsers when available.

🔐 Huntress warns that hard-coded cryptographic keys in Gladinet CentreStack and Triofox allow attackers to decrypt or forge access tickets, exposing sensitive files such as web.config. The flaw stems from a function that returns the same 100-byte strings to derive persistent keys, enabling indefinite reuse of crafted URLs to download server configuration. Organisations should update to version 16.12.10420.56791 and rotate machine keys immediately.

🔒 Fortinet has released patches for two critical cryptographic signature vulnerabilities, CVE-2025-59718 and CVE-2025-59719, that can allow an unauthenticated attacker to bypass FortiCloud SSO using a crafted SAML message on affected FortiOS, FortiWeb, FortiProxy and FortiSwitchManager devices. Administrators are advised to disable FortiCloud SSO immediately if it is enabled, apply vendor updates to non‑vulnerable versions, and then re-enable SSO only after verifying patches. Fortinet notes the feature is not enabled by factory default but can be activated during FortiCare registration; the company and responders recommend using the System -> Settings toggle or the CLI command sequence to disable login until patched.

⚠️ Researchers found that .NET HTTP client proxy classes will accept file:// and other non-HTTP schemes, invoking the filesystem handler and enabling attacker-controlled writes to arbitrary files. This unexpected behavior enabled proof-of-concept remote code execution via web shells and malicious PowerShell scripts in multiple products, including Barracuda, Ivanti, Umbraco, Microsoft PowerShell, and SQL Server Integration Services. Microsoft says it will not change the Framework behavior and places responsibility on application developers to avoid passing untrusted URLs and to validate WSDL imports.

⚠ Huntress reports widespread exploitation of the maximum-severity React Server Components flaw CVE-2025-55182, with attackers leveraging vulnerable Next.js instances to deploy cryptocurrency miners and multiple novel Linux malware families. Observed payloads include the PeerBlight backdoor, CowTunnel reverse proxy and ZinFoq post-exploitation implant, alongside droppers that fetch XMRig, Sliver C2 and Kaiji variants. Activity since early December 2025 has targeted many sectors — notably construction and entertainment — and shows signs of automated scanning and exploitation tools that sometimes deploy Linux payloads to Windows hosts. Organizations should update react-server-dom-webpack, react-server-dom-parcel and react-server-dom-turbopack immediately and hunt for indicators of compromise.

🛡️WatchTowr Labs has disclosed SOAPwn, an "invalid cast" vulnerability in the .NET Framework that lets attackers abuse WSDL imports and dynamically generated SOAP client proxies to write files and achieve remote code execution. The issue impacts products including Barracuda Service Center RMM, Ivanti Endpoint Manager (EPM), and Umbraco 8. Barracuda addressed the flaw in Service Center RMM 2025.1.1 (CVE-2025-34392, CVSS 9.8) and Ivanti issued fixes in EPM 2024 SU4 SR1 (CVE-2025-13659, CVSS 8.8). Researchers presented the findings at Black Hat Europe after disclosures in March 2024 and July 2025.

🔒 Ivanti released EPM 2024 SU4 SR1 to address a critical stored XSS vulnerability (CVE-2025-10573) that lets unauthenticated attackers hijack administrator sessions by submitting malicious device scan data to the incoming API. The update also fixes three high-severity flaws that can enable code execution with user interaction and an issue that permits unauthorized file writes. Ivanti said reports came through its responsible disclosure program and it was not aware of active exploitation at disclosure. Organizations with internet-facing or high-privilege EPM instances should apply the patch immediately and isolate management interfaces until updated.

⚠️ The PCI Special Interest Group (PCI-SIG) disclosed three vulnerabilities in the PCIe Integrity and Data Encryption (IDE) ECN that affect PCIe Base Specification Revision 5.0 and later, potentially allowing reordering, completion timeout redirection, and delayed posted redirection of encrypted PCIe traffic.
