EPSS

• CVE-2023-42817: 0.38% estimated exploitation activity in the next 30 days; percentile 32.21 (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 translation value with text including “%s” (from “%suggest%) is parsed by sprintf() even though it’s supposed to be output literally to the user. The translations may be accessible by a user with comparatively lower overall access (as the translation permission cannot be scoped to certain “modules”) and a skilled attacker might be able to exploit the parsing of the translation string in the dialog box.

# Patch Next advisory brief: CVE-2023-42817

Advisory: pimcore/admin-ui-classic-bundle Cross-site Scripting vulnerability in Translations
IDs: CVE-2023-42817, GHSA-m988-7375-7g2c
Record: https://patchnext.com/advisories/cve-2023-42817 (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 5.4)
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 1.1.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist pimcore/admin-ui-classic-bundle: affected < 1.1.2; fixed in 1.1.2

## 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-m988-7375-7g2c (GitHub-reviewed advisory GHSA-m988-7375-7g2c lists affected ranges: Packagist pimcore/admin-ui-classic-bundle >=0 <1.1.2)
