Improper Input Validation in Keycloak
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Maven | org.keycloak:keycloak-core | < 11.0.0 | 11.0.0 |
| Maven | org.keycloak:keycloak-common | < 11.0.0 | 11.0.0 |
Details
As written in the advisory (Markdown source, shown as plain text).
A flaw was found in Keycloak before version 11.0.0, where the code base contains usages of ObjectInputStream without type checks. This flaw allows an attacker to inject arbitrarily serialized Java Objects, which would then get deserialized in a privileged context and potentially lead to remote code execution.
