How to Fix GHSA-44pg-c29v-hp6r

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

laravel/framework fixed: Latest secure release 
Upgrade laravel/framework to Latest secure release
laravel/framework fixed: 6.18.34 
Upgrade laravel/framework to 6.18.34
laravel/framework fixed: 7.23.2 
Upgrade laravel/framework to 7.23.2
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 laravel/framework

How to Check if You Are Affected

To determine whether your application is affected by GHSA-44pg-c29v-hp6r, inspect your project dependencies for Laravel/framework:

inspect dependencies for laravel/framework

Analyze the terminal output to locate any version of Laravel/framework in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 6.18.34), 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 Laravel/framework, 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

In laravel releases before 6.18.34 and 7.23.2. It was possible to mass assign Eloquent attributes that included the model's table name: ``` $model->fill(['users.name' => 'Taylor']); ``` When doing so, Eloquent would remove the table name from the attribute for you. This was a "convenience" feature of Eloquent and was not documented. However, when paired with validation, this can lead to unexpected and unvalidated values being saved to the database. For this reason, we have removed the automatic stripping of table names from mass-asignment operations so that the attributes go through the typical "fillable" / "guarded" logic. Any attributes containing table names that are not explicitly declared as fillable will be discarded. This security release will be a breaking change for applications that were relying on the undocumented table name stripping during mass assignment. Since this feature was relatively unknown and undocumented, we expect the vast majority of Laravel applications to be able to upgrade without issues.
