Vulnerability Title
backpack/crud Vulnerable to Cross-site Scripting
Source: CVE Program / CVE List V5
Vulnerability Description
backpack/crud provides Create, Read, Update & Delete (CRUD) functions for Backpack, a collection of Laravel packages that help users build custom administration panels. Versions prior to 5.0.13, 4.1.69, and 4.0.63 are vulnerable to cross-site scripting. An attacker could conduct a targeted phishing campaign, in order to trick users or admins into clicking a malicious link, which under very specific circumstances could give them information or possibly admin access. Versions 5.0.13, 4.1.69, and 4.0.63 patch the issue. As a workaround, manually look inside error views in `resources/views/errors` and output `e($exception->getMessage())` instead of `$exception->getMessage()`.
