How severe is CVE-2022-21445?

CVE-2022-21445 has a CVSS score of 9.8/10, rated CRITICAL. Immediate patching is strongly recommended.

Which products are affected by CVE-2022-21445?

Affected package information for CVE-2022-21445 is not yet fully mapped. Check the official advisory links for details.

How do I patch CVE-2022-21445?

No patch has shipped for CVE-2022-21445 yet — track the oracle application development framework advisory for a fixed release and apply the workarounds below in the meantime.

How do I detect CVE-2022-21445 across my infrastructure?

Inventory every oracle application development framework deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for remote code execution at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

How do I mitigate CVE-2022-21445 if there is no patch (or I can't update yet)?

Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

How does O3 Security protect against CVE-2022-21445?

O3 detects and blocks CVE-2022-21445 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2022-21445 actively exploited in the wild?

Yes. There are 3 known exploit references for CVE-2022-21445, 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-2022-21445?

CVE-2022-21445 has an EPSS (Exploit Prediction Scoring System) score of 62.0%, 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-2022-21445 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2022-21445 (Oracle ADF Faces Deserialization of Untrusted Data Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2024-09-18. CISA required all US federal civilian agencies to remediate this vulnerability by 2024-10-09. The required action was: Apply mitigations per vendor instructions 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.

What type of vulnerability is CVE-2022-21445?

CVE-2022-21445 is classified as Deserialization of Untrusted Data (CWE-502). 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.

Which products and versions are affected by CVE-2022-21445?

CVE-2022-21445 affects oracle application development framework (2 versions, e.g. 12.2.1.3.0, 12.2.1.4.0). Check the affected-products list on this page against your deployed version to confirm exposure.

When was CVE-2022-21445 published, and has it been updated?

CVE-2022-21445 was published on April 19, 2022 and was last updated on June 17, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
