⚠️ A critical privilege-escalation vulnerability in the King Addons plugin for Elementor (CVE-2025-8489, CVSS 9.8) is being actively exploited to create administrative accounts. The flaw stems from an insecure handle_register_ajax() implementation that permits unauthenticated users to specify the administrator role during registration via the "/wp-admin/admin-ajax.php" endpoint. A patch is available in version 51.1.35 (released September 25, 2025); administrators should update immediately and audit for unauthorized admin users.

🔒 Microsoft has quietly mitigated a high-severity Windows LNK vulnerability tracked as CVE-2025-9491, which attackers used to hide malicious command-line arguments inside .lnk files. The flaw relied on padding the Target field so Windows previously masked arguments beyond 260 characters, enabling persistence and malware delivery. Microsoft’s November update now shows the full Target string in Properties but does not remove malicious arguments or warn users. An unofficial 0Patch micropatch limits target strings and warns on unusually long values.

🚨 CISA added CVE-2021-26828 — an OpenPLC ScadaBR unrestricted file upload vulnerability — to its Known Exploited Vulnerabilities (KEV) Catalog after evidence of active exploitation.

Microsoft has provided no timeline for a fix and offers no workaround beyond the hover action.

🔍 ReversingLabs discovered legacy bootstrap code in Python packages that fetches and executes an installer from the unclaimed domain python-distribute.org. The zc.buildout bootstrap.py pulls distribute_setup.py, and because the domain is for sale an attacker could acquire it and serve malicious payloads. Packages including tornado and slapos.core still contain the script; it targets Python 2 and is not executed automatically during installation, but its presence increases the supply-chain attack surface if developers run it.
