CVSS 3.1
6.8 mediumCVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:NCVE-2022-3916
Medium (6.8) in redhat. EPSS 1.0% chance of exploitation in the next 30 days. Fixed in org.keycloak:keycloak-parent 20.0.2.
A flaw was found in the offline_access scope in Keycloak. This issue would affect users of shared computers more (especially if cookies are not cleared), due to a lack of root session validation, and the reuse of session ids across root and user authentication sessions. This enables an attacker to resolve a user session attached to a previously authenticated user; when utilizing the refresh token, they will be issued a token for the original user.
