Critical (9.4) in arista networks wi-fi access point. EPSS 0.2% estimated probability of exploitation activity in the next 30 days.
On this page
Arista C-260 and C-250 access points ship with fleet-wide static cryptographic keys used for firmware image verification and SSLP authentication. An attacker who is able to access these keys would be able to create modified firmware that will pass verification checks. This vulnerability is specific to the C-260 and C-250 models; other access point models enforce digitally signed upgrade images with secure boot and are not affected by this issue.

Explain CVE-2026-102166 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-102166?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-102166?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-102166 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.Opens a third-party assistant; its answer is its own, not cve.bz's.
