CVE-2026-76483

Credential exposure via undisclosed protection failure

Published Oct 7, 2026 · Updated Oct 7, 2026

Insufficiently protected credentials in Cisco License On-Prem allow attackers to obtain credentials via unspecified vectors. Cisco has not disclosed which component handles the credentials, what protection fails, or how the credentials become accessible. The required access and resulting account privileges are also undisclosed, so the exposure cannot be narrowed to an unauthenticated network path.
