Regular expression denial of service in apache tika

CVE-2022-30973GHSA-qw3f-w4pf-jh5f

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.apache.tika:tika-core 1.28.3), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

We failed to apply the fix for CVE-2022-30126 to the 1.x branch in the 1.28.2 release. In Apache Tika, a regular expression in the StandardsText class, used by the StandardsExtractingContentHandler could lead to a denial of service caused by backtracking on a specially crafted file. This only affects users who are running the StandardsExtractingContentHandler, which is a non-standard handler. This is fixed in 1.28.3.

# Patch Next advisory brief: CVE-2022-30973

Advisory: Regular expression denial of service in apache tika
IDs: CVE-2022-30973, GHSA-qw3f-w4pf-jh5f
Record: https://patchnext.com/advisories/cve-2022-30973 (revision 1, source checked 26 Oct 2026, 16:12 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.apache.tika:tika-core 1.28.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.apache.tika:tika-core: affected >= 1.17, < 1.28.3; fixed in 1.28.3

## Suggested inspection (read-only)
- Maven org.apache.tika:tika-core: 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.tika:tika-core.
- 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-qw3f-w4pf-jh5f (GitHub-reviewed advisory GHSA-qw3f-w4pf-jh5f lists affected ranges: Maven org.apache.tika:tika-core >=1.17 <1.28.3)

Commands are suggestions: review each one before running it.
