Arbitrary code execution via incomplete class blocklist
Published Aug 18, 2025 · Updated Nov 4, 2025
Expression injection in all versions of Apache Commons OGNL allows attackers to execute arbitrary code through untrusted expressions. Ognl.getValue parses and evaluates caller-supplied expressions, while OgnlRuntime relies on an incomplete class-and-method blocklist that can be bypassed with unlisted class objects. Exploitation requires a consuming application to pass attacker-controlled expressions to the API; successful execution runs with that application's Java process privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
