nginx-ui Multiple Vulnerabilities Allow Security Bypass, CVSS 8.1
Summary
CERT-Bund issued security advisory WID-SEC-2026-1188 disclosing multiple vulnerabilities in nginx-ui, an open-source web interface for managing Nginx configurations. The vulnerabilities enable attackers to bypass security measures and facilitate further attacks. Affected versions are nginx-ui prior to 2.3.4 and prior to 2.3.5. The CVSS Base Score is 8.1 (high) with a Temporal Score of 7.3 (high), and remote attack capability is confirmed.
“Ein Angreifer kann mehrere Schwachstellen in nginx-ui ausnutzen, um Sicherheitsvorkehrungen zu umgehen, wodurch weitere Angriffe ermöglicht werden.”
Administrators and security teams should inventory nginx-ui deployments across their infrastructure and verify running versions against the affected thresholds (below 2.3.4 and below 2.3.5). The CVSS 8.1 score and confirmed remote attack vector indicate this is not a low-priority patch—prioritizing upgrade to a patched version reduces exposure to exploitation.
What changed
CERT-Bund disclosed multiple vulnerabilities in the open-source nginx-ui application that allow attackers to bypass security mechanisms and enable further attacks. The advisory assigns a CVSS Base Score of 8.1 (high) and confirms a remote attack vector. Two version thresholds are affected: nginx-ui versions below 2.3.4 and versions below 2.3.5.
Organizations and administrators running nginx-ui should assess whether any deployments meet the affected version criteria. Given the high CVSS score and confirmed remote exploitability, unpatched instances represent a significant security risk. Upgrading to version 2.3.4 or 2.3.5 as appropriate is the recommended mitigation.
