GHSA-78vg-7v27-hj67
HIGHauditor-bundle vulnerable to Cross-site Scripting because name of entity does not get escaped
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Blast Radius
damienharper/auditor-bundleReal-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
Summary
Unescaped entity property enables Javascript injection.
Details
I think this is possible because %source_label% in twig macro is not escaped. Therefore script tags can be inserted and are executed.
PoC
- clone example project https://github.com/DamienHarper/auditor-bundle-demo
- create author with FullName <script>alert()</script>
- delete author
- view audit of authors
- alert is displayed
Impact
persistent XSS. JS can be injected and executed.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for damienharper/auditor-bundle. 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 damienharper/auditor-bundle to 5.2.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-78vg-7v27-hj67 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-78vg-7v27-hj67 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-78vg-7v27-hj67. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-78vg-7v27-hj67 in your dependencies?
O3 detects GHSA-78vg-7v27-hj67 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
