Users are advised to install the updates promptly to mitigate crash and memory-corruption risks.

🔒 Threat actors are actively exploiting a critical authentication bypass in the JobMonster WordPress theme (CVE-2025-5397) that can lead to administrator account takeover under specific conditions. The flaw affects all versions up to 4.8.1 and is caused by the theme's check_login() function trusting external social login data without proper verification. To succeed, attackers typically need social login enabled and knowledge of an admin username or email. The issue is fixed in 4.8.2; immediate mitigations include upgrading, disabling social login, enabling two‑factor authentication, rotating credentials, and reviewing access logs.

🔒 Microsoft has issued updates to address three previously unknown flaws in the Windows Graphics Device Interface (GDI) that could permit remote code execution and information disclosure. The issues, rooted in malformed EMF/EMF+ records, cause out-of-bounds memory access in GdiPlus.dll and gdi32full.dll during image rendering, thumbnailing and print initialization. Patches were released across the May, July and August 2025 Patch Tuesdays (KB5058411, KB5062553, KB5063878); administrators should apply updates promptly and avoid opening untrusted EMF files.

⚠️ An out-of-band update, KB5070881, that addressed CVE-2025-59287 for Windows Server Update Service inadvertently removed Hotpatch enrollment on a very limited number of Windows Server 2025 machines. Microsoft has stopped offering KB5070881 to Hotpatch-enrolled devices and released KB5070893 the next day to fix the flaw without breaking Hotpatch. Systems that installed the buggy update will receive regular monthly security updates requiring restarts in November and December and will rejoin Hotpatch after the January 2026 baseline. As part of mitigations, Microsoft also disabled the display of WSUS synchronization error details.

⚠️ Microsoft confirmed a known issue where closing Task Manager does not terminate the taskmgr.exe process after installing the October 28, 2025 preview update (KB5067036). Multiple background instances can consume CPU and cause stutters. As a temporary workaround, end each process in a new Task Manager window or run: taskkill.exe /im taskmgr.exe /f while Microsoft investigates a permanent fix.

🛡️ The Australian Signals Directorate (ASD) has issued a bulletin warning of ongoing attacks using a Lua-based implant dubbed BADCANDY to compromise unpatched Cisco IOS XE devices via CVE-2023-20198. ASD reports variations have been seen since October 2023 and estimates about 400 Australian devices were compromised since July 2025, with 150 infections in October. Operators are urged to apply patches, restrict public access to the web UI, and follow Cisco hardening guidance.

🔒 Cybersecurity agencies in the United States, Australia and Canada have issued coordinated best-practice guidance to help organizations harden on-premises Microsoft Exchange Server installations against ongoing attacks and misconfiguration risks.

It also urges stronger authentication and encryption, dedicated administrative workstations, and built-in protections such as Microsoft Defender Antivirus and App Control to reduce attack surfaces.

🔒 CISA confirmed that CVE-2024-1086, a high-severity use-after-free bug in the nf_tables component of the Linux kernel, is being exploited in ransomware campaigns. The flaw, introduced in 2014 and patched in January 2024, enables local attackers to escalate to root. A publicly released PoC targets kernels 5.14–6.6. CISA added the issue to its KEV list and recommended mitigations such as blocklisting nf_tables, restricting user namespaces, or loading the LKRG module.

🔍 This post investigates why Cloudflare returned ENHANCE_YOUR_CALM for internal HTTP/2 traffic and traces the issue to an easy-to-make Go client behavior. An incorrect pattern where a response is closed without being fully read caused the Go HTTP/2 library to emit RST_STREAM and PING frames in quick succession, triggering PING-flood mitigations. The fix: always drain response bodies (for example, io.Copy(io.Discard, resp.Body)) before calling Close().

🔒 CISA, the NSA and international partners have issued urgent guidance to harden on‑premises Microsoft Exchange Server instances by restricting administrative access, enforcing multi‑factor authentication, and applying strict transport security. The agencies recommend migrating or decommissioning end‑of‑life and hybrid Exchange servers, enabling the Exchange Emergency Mitigation Service, and disabling remote PowerShell for users. Organizations are also advised to maintain patch cadence, apply security baselines, and enable antivirus, EDR, ASR, and AppLocker controls.

🛡️ CISA has added the high-severity flaw CVE-2025-41244, impacting Broadcom VMware Tools and VMware Aria Operations, to its Known Exploited Vulnerabilities catalog after reports of active exploitation. The bug (CVSS 7.8) allows a malicious local, non-administrative user with VM access and SDMP enabled to escalate privileges to root on the same VM. Broadcom-owned VMware released a patch last month, but NVISO Labs says the zero-day was exploited in the wild since mid-October 2024 and attributes activity to a China-linked actor tracked as UNC5174. Federal civilian agencies must implement mitigations by November 20, 2025.

⚠️ CISA has ordered Federal Civilian Executive Branch agencies to remediate a high-severity vulnerability in Broadcom's VMware Aria Operations and VMware Tools (CVE-2025-41244), patched by Broadcom in October 2024. The flaw enables a local, non-administrative user on a VM to escalate privileges to root when Aria Operations’ SDMP is enabled or when VMware Tools runs in credential-less mode. Agencies must patch within three weeks under BOD 22-01; CISA also urges all organizations to prioritize mitigations or discontinue affected products if no fix is available.

⚠️ King Addons for Elementor, installed on over 10,000 WordPress sites, contains two unauthenticated critical vulnerabilities that can enable full site takeover. Patchstack identified an arbitrary file upload (CVE-2025-6327) and a registration-based privilege escalation (CVE-2025-6325) that allow remote attackers to place files in web-accessible directories and create administrative accounts. The vendor released version 51.1.37 to add a role allowlist, input sanitization, upload permission checks and stricter file-type validation — administrators should update immediately and verify whether the 'King Addons Login | Register Form' widget is active.

🔒 CISA and the NSA, joined by the Australian Cyber Security Centre and the Canadian Centre for Cyber Security, released guidance to harden on-premises and hybrid Microsoft Exchange servers against attacks.
