Administrators should rotate credentials, limit who and what can reach ISE, and install the vendor patch as soon as service downtime allows.

⚠️ Multiple Cisco switch models are entering reboot loops after an apparent firmware bug in the internal DNS client began treating DNS lookup failures as fatal errors. The problem began around 2 AM and affected devices log fatal DNS_CLIENT errors (for example 'SRCADDRFAIL' when resolving 'www.cisco.com'), then reboot every few minutes, seriously disrupting network operations. Administrators report affected lines include CBS, SG and Catalyst C1200/C1300 series. Temporary mitigations include disabling DNS or SNTP on management interfaces or blocking outbound management access while Cisco investigates.

⚠️ Hitachi Energy has disclosed a critical remote code execution vulnerability in Asset Suite, caused by a Java deserialization flaw in the Jaspersoft library (CVE-2025-10492). The issue affects Asset Suite versions 9.7 and earlier and carries a CVSS v3.1 base score of 9.8 — allowing attackers to execute arbitrary code on vulnerable systems. Hitachi Energy advises upgrading to version 9.8 to remediate the defect. Until patched, administrators should restrict loading of external custom reports, segment networks, and deny internet exposure for control system devices.

🔒 A critical vulnerability in jsPDF (CVE-2025-68428) affected Node.js deployments and allowed untrusted input passed to file-handling APIs to produce arbitrary file reads and local file inclusion. Endor Labs found that methods like addImage, html, and addFont relied on an insecure loadFile() call, enabling attackers to embed sensitive files into generated PDFs. Maintainers released jsPDF 4.0.0 to restrict filesystem access via Node.js permission mode, but researchers warn upgrading alone may not fully mitigate risk in environments without properly configured runtime permissions.

🔒 Cisco has issued updates to address a medium-severity XML parsing vulnerability (CVE-2026-20029, CVSS 4.9) in Identity Services Engine (ISE) and ISE Passive Identity Connector. The flaw in the licensing feature allows an authenticated administrator to upload a crafted file and read arbitrary files from the underlying operating system. Cisco lists specific fixed releases and patches (pre-3.2 must migrate; 3.2/3.3/3.4 have patches; 3.5 not vulnerable), reports no workaround, and acknowledges a public PoC while noting no known in-the-wild exploitation. The advisory also includes fixes for two Snort 3 DCE/RPC issues affecting multiple Cisco products.

🔴 Security researchers disclosed a critical vulnerability in the AI workflow automation platform n8n—dubbed “Ni8mare” (CVE-2026-21858)—with a CVSS score of 10.0 that allows remote, unauthenticated attackers to read files and potentially achieve code execution on local instances. The flaw arises from improper webhook parsing of the Content-Type header, letting adversaries control file metadata and local file paths. n8n has issued a patch; users should upgrade to 1.121.0 or later as there are no official workarounds.

🔒 Researchers disclosed 11 critical vulnerabilities in Coolify, an open-source self-hosting platform, including multiple authenticated command injections, remote code execution, container escape and an information disclosure of the root SSH private key.

🔒 Veeam has released a patch addressing four vulnerabilities in Backup & Replication v13 that let users with Backup Admin, Backup Operator, or Tape Operator roles exceed intended privileges. The most severe, CVE-2025-59470 (CVSS 9.0), can enable remote code execution as the Postgres user; others permit file writes as root or RCE via malicious configuration files. Veeam recommends immediate installation of version 13.0.1.1071; the vendor says core backup data remains immutable and intact.

⚠ The jsPDF library contains a critical local file inclusion and path traversal vulnerability (CVE-2025-68428) that can embed sensitive files from the local filesystem into generated PDFs when user-controlled input is passed to file-loading APIs. The issue affects Node.js builds (dist/jspdf.node.js and dist/jspdf.node.min.js) and functions such as loadFile, addImage, html, and addFont. The bug was addressed in jsPDF 4.0.0 by restricting filesystem access by default; maintainers recommend upgrading, sanitizing input paths, and using modern Node.js permission modes.

⚠️ Researchers at Cyera disclosed a critical vulnerability in n8n (CVE-2026-21858) that allows unauthenticated attackers to read arbitrary local files via content-type parsing confusion and then recreate session cookies to assume any user’s identity. Exploitation can yield administrator privileges and remote code execution through the Execute Command node. The bug was patched in version 1.121.0 on Nov. 18; administrators should update immediately.

⚠️Logitech's Options+ and G HUB apps on macOS stopped launching after their code-signing certificate expired, preventing users from accessing custom gestures, button mappings, lighting presets, and other saved settings. Logitech acknowledged the outage on its support portal and said it will push a new macOS installer that preserves user profiles without changing the visible app version. Community-proposed workarounds include rolling the system date back, installing older builds, or blocking network access, but these are unverified and may have trade-offs. Until an official update is released, users are advised not to delete configuration files to avoid losing customizations.

⚠️ A maximum-severity vulnerability (CVE-2026-21858, 10/10) lets unauthenticated remote attackers fully compromise self-hosted n8n instances by exploiting a content-type parsing flaw in webhook/form handling. Cyera reports more than 100,000 vulnerable servers. The bug allows attackers to control file metadata in req.body.files, enabling arbitrary file reads, secret exfiltration, session forgery and potential command execution. n8n recommends updating to 1.121.0 and restricting public webhook endpoints.

🔒 Microsoft is investigating a bug in the classic Outlook client introduced by Current Channel Version 2511 (Build 19426.20218) that prevents recipients from opening messages encrypted with Encrypt Only permissions. Impacted users may see a reading pane error asking them to verify credentials or encounter a message_v2.rpmsg attachment instead of readable content. The Outlook Team is working on a fix but has not provided an ETA. Microsoft recommends two temporary workarounds: have senders save encrypted messages before sending, or roll back to build 16.0.19426.20186.
