How to Fix CVE-2022-25273

To remediate this vulnerability, upgrade all affected Drupal/core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

drupal/core fixed: 9.2.18 
Upgrade drupal/core to 9.2.18
drupal/core fixed: 9.3.12 
Upgrade drupal/core to 9.3.12
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for drupal/core

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-25273, inspect your project dependencies for Drupal/core:

inspect dependencies for drupal/core

Analyze the terminal output to locate any version of Drupal/core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 9.2.18), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Drupal/core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Drupal core's form API has a vulnerability where certain contributed or custom modules' forms may be vulnerable to improper input validation. This could allow an attacker to inject disallowed values or overwrite data. Affected forms are uncommon, but in certain cases an attacker could alter critical or sensitive data. Drupal 7 is not affected.
