# Patch Next advisory brief: CVE-2020-25802

Advisory: Improper Control of Dynamically-Managed Code Resources in Crafter CMS Crafter Studio
IDs: CVE-2020-25802, GHSA-wq3v-3grq-6f86
Record: https://patchnext.com/advisories/cve-2020-25802 (revision 1, source checked 26 Oct 2026, 16:06 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.2)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.craftercms:crafter-studio 3.1.7, 3.0.27. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.craftercms:crafter-studio: affected >= 3.0, < 3.0.27; >= 3.1, < 3.1.7; fixed in 3.0.27, 3.1.7

## Suggested inspection (read-only)
- Maven org.craftercms:crafter-studio: 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.craftercms:crafter-studio.
- 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-wq3v-3grq-6f86 (GitHub-reviewed advisory GHSA-wq3v-3grq-6f86 lists affected ranges: Maven org.craftercms:crafter-studio >=3.0 =3.1 <3.1.7)

Commands are suggestions: review each one before running it.
