GHSA-2v88-qq7x-xq5f is a high-severity (CVSS 8) CWE-116 vulnerability in pimcore/pimcore. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-2v88-qq7x-xq5f is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Real-World Exposure
pimcore/pimcoreReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
Pimcore is an open source data & experience management platform. Prior to version 10.1.2, an authenticated user could add XSS code as a value of custom metadata on assets. There is a patch for this issue in Pimcore version 10.1.2. As a workaround, users may apply the patch manually.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | pimcore/pimcore | all versions | 10.1.2 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pimcore/pimcore. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update pimcore/pimcore to 10.1.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2v88-qq7x-xq5f is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-2v88-qq7x-xq5f is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-2v88-qq7x-xq5f. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
