Microsoft responds to security challenges facing code, AI agents, and models

Microsoft has introduced a series of security tools and capabilities focused on AI-driven vulnerability discovery, AI agents, and AI models. The updates include a multi-agent vulnerability discovery system, new controls for managing and securing AI agents, data protection capabilities, and tools designed to identify potentially vulnerable or compromised AI models before deployment. MDASH targets exploitable vulnerabilities Microsoft expanded the preview of MDASH, a multi-model agentic vulnerability discovery system that now integrates with Microsoft Defender.

Simplify security management with CIS SecureSuite Platform

New operating systems prioritize usability, a reality which threat actors use to exploit security gaps. Every misconfiguration creates an opportunity for compromise, and lean teams struggle in their security management efforts to harden hundreds or thousands of endpoints. CIS SecureSuite Membership simplifies the process with tools, benefits, and resources for implementing the secure recommendations of the CIS Benchmarks. With the release of our CIS SecureSuite Platform, it’s now even easier for Members to harden their … More → The post Simplify security management with CIS SecureSuite Platform appeared first on Help Net Security.

Autonomous AI-driven worm can reason its way through corporate networks

Researchers at the University of Toronto, the Vector Institute, and the University of Cambridge have built and tested a proof-of-concept AI-driven worm that does not operate on a fixed list of exploits. Instead, it analyzes each target it encounters, reasons about how to attack it, and creates a strategy on the fly, all with the help of a small, free large language model (LLM) running directly on machines it has already compromised. A worm that … More → The post Autonomous AI-driven worm can reason its way through corporate networks appeared first on Help Net Security.

Cisco Webex Meetings Cross-Site Scripting Vulnerability

A vulnerability in the web-based user interface of Cisco Webex Meetings could have allowed an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack. Cisco has addressed this vulnerability in the Webex Meetings service, and no customer action is needed. This vulnerability existed because of insufficient validation of user input. Prior to this vulnerability being addressed, an attacker could have exploited this vulnerability by persuading a user to follow a malicious link. A successful exploit could have allowed the attacker to execute arbitrary script code in the browser of the targeted user or access sensitive, browser-based information. As mentioned, Cisco has addressed this vulnerability in the Webex Meetings service, and no customer action is necessary to update on-premises software or devices. There are no workarounds that address this vulnerability. This advisory is available at the following link: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webex-xss-jw3NeQzS Security Impact Rating: Medium CVE: CVE-2026-20233

Cisco Unified Communications Manager Server-Side Request Forgery Vulnerability

A vulnerability in Cisco Unified Communications Manager (Unified CM) and Cisco Unified Communications Manager Session Management Edition (Unified CM SME) could allow an unauthenticated, remote attacker to conduct server-side request forgery (SSRF) attacks through an affected device. This vulnerability is due to improper input validation for specific HTTP requests. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to write files to the underlying operating system that could be used later to elevate to root. Note: Cisco has assigned this security advisory a Security Impact Rating (SIR) of Critical rather than High as the score indicates. The reason is that exploitation of this vulnerability could result in an attacker elevating privileges to root. Note: To exploit this vulnerability, the WebDialer service must be enabled. WebDialer is disabled by default. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. This advisory is available at the following link: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cucm-ssrf-cXPnHcW Security Impact Rating: Critical CVE: CVE-2026-20230

Cisco Finesse Remote File Inclusion Vulnerability

A vulnerability in Cisco Finesse could allow an unauthenticated, remote attacker to load arbitrary files from remote locations into an active user session on an affected device, possibly leading to browser-based attacks. This vulnerability is due to insufficient validation of user-supplied input for HTTP requests that are sent to an affected device. An attacker who has knowledge of the address of the affected device could exploit this vulnerability by persuading a user to click a crafted link that contains the affected device address. A successful exploit could allow the attacker to conduct browser-based attacks and execute arbitrary script code in the context of the affected interface or access sensitive information on the affected device. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. This advisory is available at the following link: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-finesse-rfi-gwpkdc89 Security Impact Rating: Medium CVE: CVE-2026-20175

Only 11% of production agents pass the AI agent security bar

Enterprise teams are running AI agents that write code, drive browsers, answer customer calls, manage cloud infrastructure, and query data warehouses with standing credentials. A new independent assessment of 100 production agents finds that nearly all of them carry the conditions for a single hostile document to take them over. The AI Risk Quadrant (AIRQ) report, a 2026 Q2 edition produced by independent researchers, scores 100 commercial and publicly available AI agents across three dimensions: … More → The post Only 11% of production agents pass the AI agent security bar appeared first on Help Net Security.
