Cisco Warns of Attackers Exploiting Critical Authentication Bypass in SD-WAN Manager

The Hacker News

Cisco has issued a warning about a critical zero-day vulnerability affecting its Catalyst SD-WAN Manager, which is used by companies to oversee their SD-WAN networks. The flaw, identified as CVE-2026-76504, allows remote attackers to exploit the system's API without needing any login credentials, essentially granting them admin-level access. This poses a significant risk to organizations using this management software, as it could lead to unauthorized control and potential data breaches. Cisco has released patches to fix the issue, but there are no workarounds available for users who need immediate protection. Companies are urged to apply the fixes as soon as possible to mitigate the risk of exploitation.

AI's Third Wave: Coworkers Break the Security Model That Worked for Agents

BleepingComputer

The article discusses emerging security risks associated with persistent AI coworkers, which operate continuously and often have standing access to systems. This creates identity risks that current security models are not equipped to handle. Experts from Token Security emphasize the need for these AI agents to have their own distinct identities, designated owners, and carefully scoped permissions to mitigate potential security issues. Additionally, implementing lifecycle controls for these agents is crucial to ensure that they do not pose an ongoing risk. As AI increasingly integrates into workplaces, addressing these identity and access challenges is vital to protect sensitive information and maintain organizational security.
