Laravel: XSS in Debug Page Information

CVE-2026-102279GHSA-jh5r-qr3c-85q8

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (laravel/framework 13.30.0, 12.69.0), 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-2026-102279

Advisory: Laravel: XSS in Debug Page Information
IDs: CVE-2026-102279, GHSA-jh5r-qr3c-85q8
Record: https://patchnext.com/advisories/cve-2026-102279 (revision 2, source checked 26 Oct 2026, 14:53 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Low (CVSS 3.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: laravel/framework 13.30.0, 12.69.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist laravel/framework: affected < 12.69.0; >= 13.0.0, < 13.30.0; fixed in 12.69.0, 13.30.0

## 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.
