The score given by the assigning authority versus NVD’s independent score. A gap means the severity is contested.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Apr 11, 2024. That signals real attacks, not theory.

Remediation deadline for government agencies: May 2, 2024.
