GHSA-78vg-7v27-hj67 is a high-severity (CVSS 8.2) Cross-site Scripting (XSS) vulnerability in damienharper/auditor-bundle. A fix is available for damienharper/auditor-bundle — see the affected versions and patch details below.
auditor-bundle vulnerable to Cross-site Scripting because name of entity does not get escaped
Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- A successful exploit gives an attacker total control of the affected component, not partial access.

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.
How urgent is this, really
GHSA-78vg-7v27-hj67 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,333 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure

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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-78vg-7v27-hj67 can be triaged on real exposure rather than presence alone.
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 Security finds GHSA-78vg-7v27-hj67 across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
