• CVE-2022-33980: 44.64% estimated exploitation activity in the next 30 days; percentile 98.77 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Apache Commons Configuration performs variable interpolation, allowing properties to be dynamically evaluated and expanded. The standard format for interpolation is "${prefix:name}", where "prefix" is used to locate an instance of org.apache.commons.configuration2.interpol.Lookup that performs the interpolation. Starting with version 2.4 and continuing through 2.7, the set of default Lookup instances included interpolators that could result in arbitrary code execution or contact with remote servers. These lookups are: - "script" - execute expressions using the JVM script execution engine (javax.script) - "dns" - resolve dns records - "url" - load values from urls, including from remote servers Applications using the interpolation defaults in the affected versions may be vulnerable to remote code execution or unintentional contact with remote servers if untrusted configuration values are used. Users are recommended to upgrade to Apache Commons Configuration 2.8.0, which disables the…

# Patch Next advisory brief: CVE-2022-33980

Advisory: Code injection in Apache Commons Configuration
IDs: CVE-2022-33980, GHSA-xj57-8qj4-c4m6
Record: https://patchnext.com/advisories/cve-2022-33980 (revision 1, source checked 26 Oct 2026, 16:05 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.apache.commons:commons-configuration2 2.8.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.apache.commons:commons-configuration2: affected >= 2.4, < 2.8.0; fixed in 2.8.0

## Suggested inspection (read-only)
- Maven org.apache.commons:commons-configuration2: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.apache.commons:commons-configuration2.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-xj57-8qj4-c4m6 (GitHub-reviewed advisory GHSA-xj57-8qj4-c4m6 lists affected ranges: Maven org.apache.commons:commons-configuration2 >=2.4 <2.8.0)
