GHSA-qvrv-2x7x-78x2 is a medium-severity (CVSS 6.1) Cross-site Scripting (XSS) vulnerability in silverstripe/framework. O3 Security confirms whether GHSA-qvrv-2x7x-78x2 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Reflected XSS in SilverStripe
Real-World Exposure
silverstripe/framework🐘silverstripe/frameworkReal-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
SilverStripe through 4.4.x before 4.4.5 and 4.5.x before 4.5.2 allows Reflected XSS on the login form and custom forms. Silverstripe Forms allow malicious HTML or JavaScript to be inserted through non-scalar FormField attributes, which allows performing XSS (Cross-Site Scripting) on some forms built with user input (Request data). This can lead to phishing attempts to obtain a user's credentials or other sensitive user input.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | silverstripe/framework | ≥ 4.5.0&&< 4.5.2 | 4.5.2 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for silverstripe/framework. 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 silverstripe/framework to 4.5.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qvrv-2x7x-78x2 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-qvrv-2x7x-78x2 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-qvrv-2x7x-78x2. 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-qvrv-2x7x-78x2 in your dependencies?
O3 detects GHSA-qvrv-2x7x-78x2 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
