Improper Input Validation in Keycloak
CVE-2020-1714 · GHSA-m6mm-q862-j366
- Affected
- Maven org.keycloak:keycloak-common < 11.0.0
- Fixed in
- 11.0.0· Vendor fix available
- Issue
- 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.
Recommended action: Upgrade to 11.0.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
