The nginx project released njs 1.0.1, updating its JavaScript extension for nginx HTTP processing. The release remediates three vulnerabilities: CVE-2026-78689, CVE-2026-18329, and CVE-2026-78222, affecting the xml.exclusiveC14n, js_access, and ngx.fetch functionality.
The update was announced alongside nginx 1.31.5, a mainline development release. Organizations using njs should review their exposure to the affected APIs and upgrade to njs 1.0.1; nginx 1.30.x remains the maintained stable branch for serious bug and security fixes, while the 1.31.x line is expected to form the future nginx 1.32 stable release.
