# Patch Next advisory brief: CVE-2019-10202

Advisory: Deserialization of Untrusted Data in org.codehaus.jackson:jackson-mapper-asl
IDs: CVE-2019-10202, GHSA-c27h-mcmw-48hv
Record: https://patchnext.com/advisories/cve-2019-10202 (revision 1, source checked 26 Oct 2026, 16:10 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 response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.codehaus.jackson:jackson-mapper-asl: affected <= 1.9.13

## Suggested inspection (read-only)
- Maven org.codehaus.jackson:jackson-mapper-asl: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.codehaus.jackson:jackson-mapper-asl.
- 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-c27h-mcmw-48hv (GitHub-reviewed advisory GHSA-c27h-mcmw-48hv lists affected ranges: Maven org.codehaus.jackson:jackson-mapper-asl >=0 <=1.9.13)

Commands are suggestions: review each one before running it.
