CVE-2026-75034

7.4 highEPSS 0.3%

High (7.4) in suse rancher. EPSS 0.3% chance of exploitation in the next 30 days.

A flaw was found in Rancher Manager. The SAML assertion replay protection introduced by the fix for CVE-2026-44946 recorded consumed assertion IDs in a per-process cache, so each replica only detected replays that reached the same pod. In a high-availability deployment, an attacker holding a captured assertion could replay it once against every other replica to obtain additional authenticated sessions as the victim. This issue affects Rancher: before 2.15.1.
