How to Fix CVE-2024-21627

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

prestashop/prestashop fixed: 8.1.3 
Upgrade prestashop/prestashop to 8.1.3
prestashop/prestashop fixed: 1.7.8.11 
Upgrade prestashop/prestashop to 1.7.8.11
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 prestashop/prestashop

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-21627, inspect your project dependencies for Prestashop/prestashop:

inspect dependencies for prestashop/prestashop

Analyze the terminal output to locate any version of Prestashop/prestashop in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 8.1.3), 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 Prestashop/prestashop, 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 Some event attributes are not detected by the isCleanHTML method ### Impact Some modules using the isCleanHTML method could be vulnerable to xss ### Patches 8.1.3, 1.7.8.11 ### Workarounds The best workaround is to use the `HTMLPurifier` library to sanitize html input coming from users. The library is already available as a dependency in the PrestaShop project. Beware though that in legacy object models, fields of `HTML` type will call `isCleanHTML`. ### Reporters Reported by Antonio Russo (@Antonio-R1 on GitHub) and Antonio Rocco Spataro (@antoniospataro on GitHub).
