CVE-2020-10734: A vulnerability was found in keycloak in the way that the OIDC logout endpoint does not have CSRF protection.

LowCVSS 3.3 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 13/100)

  • 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).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: org.keycloak:keycloak-oidc-client-adapter-pom (Maven) 18.0.0.

Low priority for now. Upgrade to org.keycloak:keycloak-oidc-client-adapter-pom (Maven) 18.0.0 or later.

Root cause

State-changing requests rely on the session cookie the browser sends automatically; nothing verifies that the request came from the user’s own page.
