Why am I seeing this Ranked on corroboration — 2 independent outlets
2 independent outlets carried this — BleepingComputer and Feedburner. Agreement across newsrooms that do not share an owner is the strongest thing we can measure, so it carries the most weight.
StandardStandard, because two or more independent orgs carry it, the subject was identified from the text, and it scores 0.51 against a bar of 0.50.
| Factor | Weight | Score | Contribution | Where it came from |
|---|---|---|---|---|

| Pickup rate | 0.20 | 0.05 | +0.010 2% | The sources carry no usable publish times, so the rate could not be measured from them directly. |
| Freshness | 0.20 | 0.38 | +0.077 15% | Halves every 10 hours from the newest item on the story. This is the only factor that rewards a story for nothing more than being recent. |
Corroboration counts distinct organisations, once each, and only from tiers 1 and 2. Freshness halves every 10 hours, so this ranking is a snapshot and will differ at the next build.

What happened
Cisco has released security updates to address a maximum-severity Identity Services Engine vulnerability that attackers are actively exploiting in the wild. Cisco has warned of a fresh maximum-severity security flaw impacting Identity Services Engine (ISE) that has come under active exploitation. The vulnerability, tracked as CVE-2026-76460 (CVSS score: 10.0), could allow an unauthenticated, remote attacker to bypass authentication. "This vulnerability is due to insufficient authentication control on an API endpoint," Cisco said.
