CISA warns of active flaws in Cisco, Chrome and Arista Networks

Published on June 11, 2026 | Translated from Spanish

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added vulnerabilities in Cisco, Chrome, and Arista to its catalog of actively exploited flaws. This indicates that cybercriminals are already using these security holes to compromise systems. Administrators must apply patches immediately to mitigate risks.

Technical details of the highlighted vulnerabilities 🛡️

Among the flaws are a buffer overflow in Cisco devices allowing remote code execution, a zero-day vulnerability in Chrome's V8 engine already fixed in version 132, and an error in Arista's web interface that exposes credentials in plain text. CISA requires their remediation by March 10 for federal entities.

CISA's catalog: where bugs go to die (or live) 💻

By now, CISA's catalog looks like the guest list for a party no one wanted to host: all the famous flaws show up. Cisco, Chrome, and Arista join the collection. If your software isn't on the list, maybe it's not popular enough among hackers. Or worse, they haven't discovered it yet.
