Lack of access control on upoaded files

CVE-2019-12245GHSA-jvx5-rm6q-gx7p

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (silverstripe/assets 1.4.4, 1.3.5; silverstripe/framework 4.4.4, 4.3.6, 3.7.4, 3.6.8), 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-2019-12245

Advisory: Lack of access control on upoaded files
IDs: CVE-2019-12245, GHSA-jvx5-rm6q-gx7p
Record: https://patchnext.com/advisories/cve-2019-12245 (revision 1, source checked 26 Oct 2026, 14:15 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: silverstripe/assets 1.4.4, 1.3.5; silverstripe/framework 4.4.4, 4.3.6, 3.7.4, 3.6.8. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist silverstripe/assets: affected >= 1.0.0, < 1.3.5; >= 1.4.0, < 1.4.4; fixed in 1.3.5, 1.4.4
- Packagist silverstripe/framework: affected < 3.6.8; >= 3.7.0, < 3.7.4; >= 4.0.0, < 4.3.6; >= 4.4.0, < 4.4.4; fixed in 4.3.6, 4.4.4, 3.6.8, 3.7.4

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