Keycloak vulnerable to session hijacking via re-authentication
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Maven | org.keycloak:keycloak-services | < 22.0.10 | 22.0.10 |
| Maven | org.keycloak:keycloak-services | >= 23.0.0, < 24.0.3 | 24.0.3 |
Details
As written in the advisory (Markdown source, shown as plain text).
A flaw was found in Keycloak. An active keycloak session can be hijacked by initiating a new authentication (having the query parameter prompt=login) and forcing the user to enter his credentials once again. If the user cancels this re-authentication by clicking Restart login, the account takeover could take place as the new session, with a different SUB, will have the same SID as the previous session.
