Exploitation Status

No confirmed exploitation observed yet

  • CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
  • A successful exploit gives an attacker total control of the affected component, not partial access.
  • CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

How urgent is this, really

CVE-2024-28253 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.

Where this sits among everything scored

Of 377,166 CVEs with a current EPSS score, this one falls in the 10–50% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

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.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.open-metadata:openmetadata-service, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.open-metadata:openmetadata-service to 1.3.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-28253 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2024-28253 can be triaged on real exposure rather than presence alone.

Tailored to CVE-2024-28253. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
