How to Fix CVE-2026-47744

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

shopper/framework fixed: 2.8.0 
Upgrade shopper/framework to 2.8.0
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 shopper/framework

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-47744, inspect your project dependencies for Shopper:

inspect dependencies for shopper/framework

Analyze the terminal output to locate any version of Shopper in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.8.0), 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-269: Improper Privilege Management, where the product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. In Shopper, 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

## Impact Two distinct authorization defects in the team settings allowed any authenticated panel user to take over the RBAC system: - `Settings/Team/Index` had no `mount()` authorization. Any authenticated user could load the page and use its public actions to create new roles and delete other users, including administrators. - `Settings/Team/RolePermission` gated its write actions on the read-only `view_users` permission. Any user holding `view_users` could grant themselves or any other user arbitrary permissions, including `manage_users` and `edit_orders`, effectively escalating to full panel administrator from a read-only account. Combined, these two defects allow a low-privilege authenticated user to obtain administrator privileges and remove the legitimate administrators from the panel. ## Patches Fixed in `v2.8.0`: - `Settings/Team/Index::mount()` now authorizes against `manage_users`. - `Settings/Team/RolePermission` write actions now require `manage_users` instead of `view_users`. Upgrade via: ```bash composer require shopper/admin:^2.8 ``` ## Workarounds None. Upgrade to `v2.8.0`.
