CVE-2026-10741: Nexus Repository Manager - Incorrect Authorization allows credential disclosure via proxy repository configuration

Noroxi assessment

Priority: Monitor (action score 23/100)

  • 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: 0.27% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Sonatype Nexus Repository Manager 3.93.0.

Low priority for now. Upgrade to Sonatype Nexus Repository Manager 3.93.0 or later.
