statamic/cms fixed: 3.2.39 
Upgrade statamic/cms to 3.2.39
statamic/cms fixed: 3.3.2 
Upgrade statamic/cms to 3.3.2
Verify Direct and Transitive Dependencies

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

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-24784, inspect your project dependencies for Statamic/cms:

inspect dependencies for statamic/cms

Analyze the terminal output to locate any version of Statamic/cms in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.2.39), 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-203: Observable Discrepancy, where the product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor. In Statamic/cms, 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

## Description It was possible to confirm a single character of a user's password hash (just the hash, not the password) using a specially crafted regular expression filter in the users endpoint of the REST API. Many requests could eventually uncover the entire hash. The hash would not be in the response, however the presence or absence of a result would confirm if the character was in the right position. It would take a long time since the API has throttling enabled by default. Additionally, the REST API would need to be enabled, as well as the users endpoint. Both of which are disabled by default. ## Resolution Filtering by password or password hash has been disabled. ## Credits We would like to thank Thibaud Kehler for reporting the issue.
