EPSS

• CVE-2023-47636: 0.65% estimated exploitation activity in the next 30 days; percentile 51.39 (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 Full Path Disclosure (FPD) vulnerabilities enable the attacker to see the path to the webroot/file. e.g.: /home/omg/htdocs/file/. Certain vulnerabilities, such as using the loadfile() (within a SQL Injection) query to view the page source, require the attacker to have the full path to the file they wish to view. In the case of pimcore, the fopen() function here doesn't have an error handle when the file doesn't exist on the server so the server response raises the full path "fopen(/var/www/html/var/tmp/export-{ uniqe id}.csv)" Patches Apply patch https://github.com/pimcore/admin-ui-classic-bundle/commit/10d178ef771097604a256c1192b098af9ec57a87.patch Workarounds Update to version 1.2.1 or apply patches manually References https://huntr.com/bounties/4af4db18-9fd4-43e9-8bc6-c88aaf76839c/

# Patch Next advisory brief: CVE-2023-47636

Advisory: pimcore/admin-ui-classic-bundle Full Path Disclosure via re-export document
IDs: CVE-2023-47636, GHSA-c8hj-w239-5gvf
Record: https://patchnext.com/advisories/cve-2023-47636 (revision 1, source checked 26 Oct 2026, 14:11 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: pimcore/admin-ui-classic-bundle 1.2.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist pimcore/admin-ui-classic-bundle: affected < 1.2.1; fixed in 1.2.1

## Suggested inspection (read-only)
- Packagist pimcore/admin-ui-classic-bundle: 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/admin-ui-classic-bundle.
- 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-c8hj-w239-5gvf (GitHub-reviewed advisory GHSA-c8hj-w239-5gvf lists affected ranges: Packagist pimcore/admin-ui-classic-bundle >=0 <1.2.1)
