CVE-2026-113368: Nexus Repository 3 - Group Repository Member Authorization Bypass

MediumCVSS 5.3 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.21% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Sonatype Nexus Repository 3 3.98.0.

Low priority for now. Upgrade to Sonatype Nexus Repository 3 3.98.0 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Sonatype Nexus Repository 3 does not check that a user account is authorized to access a repository before the repository is added as a member of a group repository. A user account that has signed in with valid credentials and holds the add or edit privilege on a group repository can add a repository that the account cannot read or browse, and then read the content of that repository through the group. The anonymous user can only do this if an administrator has explicitly granted it that privilege.
