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. Alongside that, restrict the management interface to trusted networks and apply the vendor's recommended configuration mitigations.

Is CVE-2024-21182 actively exploited in the wild?

Yes. There are 2 known exploit references for CVE-2024-21182, including 1 in-the-wild exploitation observed on GitHub and other sources.

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-2024-21182?

CVE-2024-21182 has an EPSS (Exploit Prediction Scoring System) score of 74.2%, placing it in the 99th 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.

Is CVE-2024-21182 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2024-21182 (Oracle WebLogic Server Unspecified Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2026-06-01. CISA required all US federal civilian agencies to remediate this vulnerability by 2026-06-04. The required action was: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.
