## What is GHSA-44pg-c29v-hp6r?

GHSA-44pg-c29v-hp6r is a missing authorization vulnerability in laravel/framework, published on 15 May 2024. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

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.

- laravel/framework (Packagist): affected from 5.5.0 up to 5.5.49; no fix listed
- laravel/framework (Packagist): affected from 6.0.0; fixed in 6.18.34

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
