EPSS

• CVE-2023-30855: 0.80% estimated exploitation activity in the next 30 days; percentile 56.48 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Impact The impact of this path traversal and arbitrary extension is limited (creation of arbitrary files and appending data to existing files) but when combined with the SQL Injection, the exported data RESTRICTED DIFFUSION 9 / 9 can be controlled and a webshell can be uploaded. Attackers can use that to execute arbitrary PHP code on the server with the permissions of the webserver.

# Patch Next advisory brief: CVE-2023-30855

Advisory: Pimcore Path Traversal Vulnerability in AdminBundle/Controller/Reports/CustomReportController.php
IDs: CVE-2023-30855, GHSA-g2mc-fqqc-hxg3
Record: https://patchnext.com/advisories/cve-2023-30855 (revision 1, source checked 26 Oct 2026, 14:10 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: pimcore/pimcore 10.5.18. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist pimcore/pimcore: affected < 10.5.18; fixed in 10.5.18

## Suggested inspection (read-only)
- Packagist pimcore/pimcore: 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 pimcore/pimcore.
- 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-g2mc-fqqc-hxg3 (GitHub-reviewed advisory GHSA-g2mc-fqqc-hxg3 lists affected ranges: Packagist pimcore/pimcore >=0 <10.5.18)
