CVE-2026-14504: Sonatype Nexus Repository 3 authorization bypass in component upload API

CVE-2026-14504 · Severity: info · CVSS 8.2 · Published 2026-07-14

Sonatype Nexus Repository 3, a platform used by software teams to store and manage code components, contains a security flaw in its upload system. This vulnerability allows users who should only be able to view or download files to instead upload their own files into Swift, Terraform, or Conda repositories. This could allow an unauthorized person to inject malicious code or unauthorized software into a company's development pipeline, potentially compromising the integrity of software builds.
