CVE-2026-14504
An authorization bypass in Nexus Repository 3's component upload API allowed a user with only read/browse privileges on a Swift, Terraform, or Conda hosted repository to upload arbitrary artifacts, bypassing the intended write-permission check.
No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.

Affected & fixed versions by distribution
Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.
No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
