Laravel has a File Validation Bypass

CVE-2025-27515GHSA-78fx-h6xr-vch4

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (laravel/framework 12.1.1, 11.44.1, 10.48.29), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2025-27515

Advisory: Laravel has a File Validation Bypass
IDs: CVE-2025-27515, GHSA-78fx-h6xr-vch4
Record: https://patchnext.com/advisories/cve-2025-27515 (revision 1, source checked 26 Oct 2026, 14:29 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: laravel/framework 12.1.1, 11.44.1, 10.48.29. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist laravel/framework: affected >= 12.0.0, < 12.1.1; >= 11.0.0, < 11.44.1; < 10.48.29; fixed in 11.44.1, 12.1.1, 10.48.29

## Suggested inspection (read-only)
- Packagist laravel/framework: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on laravel/framework.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-78fx-h6xr-vch4 (GitHub-reviewed advisory GHSA-78fx-h6xr-vch4 lists affected ranges: Packagist laravel/framework >=12.0.0 =11.0.0 =0 <10.48.29)
