How do I fix CVE-2024-28253?

Update org.open-metadata:openmetadata-service to version 1.3.1 or later. Run your dependency manager's update command and verify no transitive dependencies pin the vulnerable version. Use O3 Security's SCA scanner to confirm the fix is applied across your entire dependency tree.

Is CVE-2024-28253 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2024-28253, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2024-28253?

CVE-2024-28253 has an EPSS (Exploit Prediction Scoring System) score of 92.9%, placing it in the 100th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

What type of vulnerability is CVE-2024-28253?

CVE-2024-28253 is classified as Code Injection (CWE-94). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Is there exploit tooling available for CVE-2024-28253?

A Nuclei detection template exists for CVE-2024-28253, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was CVE-2024-28253 published, and has it been updated?

CVE-2024-28253 was published on March 15, 2024 and was last updated on April 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

OpenMetadata is a unified platform for discovery, observability, and governance powered by a central metadata repository, in-depth lineage, and seamless team collaboration. CompiledRule::validateExpression is also called from PolicyRepository.prepare. prepare() is called from EntityRepository.prepareInternal() which, in turn, gets called from EntityResource.createOrUpdate(). Note that even though there is an authorization check (authorizer.authorize()), it gets called after prepareInternal() gets called and therefore after the SpEL expression has been evaluated. In order to reach this method, an attacker can send a PUT request to /api/v1/policies which gets handled by PolicyResource.createOrUpdate(). This vulnerability was discovered with the help of CodeQL's Expression language injection (Spring) query and is also tracked as GHSL-2023-252. This issue may lead to Remote Code Execution and has been addressed in version 1.3.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.
