High CVSS 7

CVE-2026-21064

NVD analysis in progress

Improper access control in Weaver prior to SMR Aug-2026 Release 1 allows local attackers to cause device inoperability.

What this means

Exposure: Exploitable with local access to the machine, without authentication and with no action from the victim.
Impact: An attacker can modify or destroy data and take the service offline.
Weakness: Access control is applied incorrectly, leaving a protected resource reachable without the required rights.
Likelihood: Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.

What to doFold into the next patch cycle.

Read automatically from the CVSS vector, the weakness type (CWE) and the EPSS score. The technical description above remains the one published by NIST.
