Technical Root Cause & Exploitation Mechanics

CVE-2026-111477 is currently in a 'Rejected' state, meaning it has been withdrawn by the CVE Numbering Authority (CNA). This typically occurs due to duplicate entries or the discovery that the report does not constitute a security vulnerability. However, the assigned CVSS 3.1 score of 7.5 and a significant EPSS score of 0.42 suggest that the underlying technical issue was initially perceived as a high-risk network-based threat (AV:N). Security teams should investigate if this vulnerability was merged into another active CVE ID to ensure no actual risk remains unpatched.
