Which packages are affected by CVE-2022-30333?

Affected package information for CVE-2022-30333 is not yet fully mapped. Check the official advisory links for details.

How do I fix CVE-2022-30333?

No fixed release is recorded for CVE-2022-30333 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.

How do I detect CVE-2022-30333 in my code and dependencies?

Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

How do I mitigate CVE-2022-30333 if there is no patch (or I can't update yet)?

Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.

Is CVE-2022-30333 actively exploited in the wild?

Yes. There are 11 known exploit references for CVE-2022-30333, including 8 in-the-wild exploitations 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-2022-30333?

CVE-2022-30333 has an EPSS (Exploit Prediction Scoring System) score of 99.2%, 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.

Is CVE-2022-30333 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2022-30333 (RARLAB UnRAR Directory Traversal Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2022-08-09. CISA required all US federal civilian agencies to remediate this vulnerability by 2022-08-30. The required action was: Apply updates per vendor instructions. This CVE has been used in known ransomware campaigns. 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-2022-30333?

CVE-2022-30333 is classified as Path Traversal (CWE-22), CWE-59 (CWE-59). These weakness types 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-2022-30333?

3 Metasploit modules reference CVE-2022-30333, which lowers the barrier to weaponization. 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-2022-30333 published, and has it been updated?

CVE-2022-30333 was published on May 9, 2022 and was last updated on April 16, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Exploitation Status

Actively exploited in the wild

Confirmed by CISA's Known Exploited Vulnerabilities catalog on 2022-08-09 — including use in ransomware campaigns. Federal agencies were required to remediate by 2022-08-30.
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.
