For Adobe Commerce on Cloud merchants only - How to tell whether the isolated patches have been applied

Considering that it isn’t possible to easily check if the issue was patched, you might want to check whether the VULN-27015 isolated patch has been successfully applied.

You can do this by taking the following steps, using the file VULN-27015-2.4.7_COMPOSER.patch as an example:

  1. Install the Quality Patches Tool.

  2. Run the command:

    cve-2024-34102-tell-if-patch-applied-code

  3. You should see output similar to this, where VULN-27015 returns the  Applied  status:

    code language-bash 
    ║ Id            │ Title                                                        │ Category        │ Origin                 │ Status      │ Details                                          ║ ║ N/A           │ ../m2-hotfixes/VULN-27015-2.4.7_COMPOSER_patch.patch      │ Other           │ Local                  │ Applied     │ Patch type: Custom
