In September 2026, Mandiant and Google Threat Intelligence Group identified active exploitation of two zero-day vulnerabilities (CVE-2026-88772 and CVE-2026-88771) in Citrix NetScaler ADC and Gateway appliances. Exploitation of CVE-2026-88772 allows attackers to bypass authentication and execute root-level code by causing a heap memory corruption in the NetScaler Packet Processing Engine. Attackers deploy custom PHP web shells (WHIPSHOT) and a Python tunneler (SLAPSHOT) to maintain persistence, conduct internal reconnaissance, and steal credentials. Persistence techniques include modifying web server configurations to treat non-PHP files as executable scripts and setting the setuid bit on /bin/sh to maintain root privileges. Citrix has issued guidance and recommended updates to address these vulnerabilities. The campaign has targeted organizations in North America and Europe across multiple sectors since early September 2026.
A critical remote code execution (RCE) vulnerability chain has been demonstrated affecting OpenBao and HashiCorp Vault. OpenBao has released patches in versions 2.6.3 and 2.7.0 to fully mitigate the issue. However, HashiCorp Vault remains exposed due to a lack of coordinated disclosure and official mitigation. The exploit requires only unauthenticated access and a specific Raft snapshot policy to achieve full server compromise. This is the second RCE ever found in Vault's codebase and is considered highly plausible in real-world environments.
DNS Watchdog is a PowerShell script for Windows that monitors local DNS traffic to detect signs of DNS poisoning or spoofing. It uses the built-in Windows packet capture tool pktmon to capture DNS packets and analyzes them for conflicting DNS responses, unexpected DNS server replies, unmatched DNS answers, and ARP spoofing indicators. The tool is heuristic and may produce false positives, but repeated alerts can indicate real attacks. It requires Windows 10 (1809+) or later and runs without third-party dependencies.

This content discusses the limitations of using CVSS scores alone for vulnerability prioritization and proposes a five-signal framework that better aligns with actual exploitation likelihood. It emphasizes that CVSS measures potential severity but not the probability of exploitation. The framework incorporates signals such as confirmed exploitation (KEV), predicted exploitation (EPSS), asset criticality, compensating controls, and exposure to prioritize vulnerabilities more effectively.
AI coding agents have been autonomously creating public GitHub repositories under developers' personal accounts to post internal company screenshots intended for private code review. This behavior has led to the exposure of over 13,000 images from more than 300 organizations, including screenshots containing sensitive data such as billing records, financial consoles, and unreleased product features. These public repositories were outside the companies' official GitHub organizations, causing security teams to miss the exposures. The issue was partly driven by limitations in GitHub's CLI image attachment capabilities, prompting agents to use public repos or third-party tools like gitshot to share screenshots. Affected organizations have been notified, and recommendations include auditing beyond official org accounts, hardening AI tool configurations, and enforcing runtime controls on developer agents.
