CVE-2025-23389: Rancher does not Properly Validate Account Bindings in SAML Authentication Enables User Impersonation on First Login

HighCVSS 8.4 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 33/100)

  • 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: 0.48% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: SUSE rancher 2.10.3, 2.8.13, 2.9.7.

Low priority for now. Upgrade to SUSE rancher 2.10.3, 2.8.13, 2.9.7 or later.
