A SAML authentication replay vulnerability in Rancher's Assertion Consumer Service (ACS) handler did not enforce one-time use of SAML assertion, potentially allowing person in the middle attacks against Rancher, affecting Rancher 2.14.0 before 2.14.3,
CVE-2026-44946
This high-severity CVE scores 7.4 under NVD CVSS v3. EPSS exploit probability: 0.4%, top 68% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
