GHSA-x78v-4fvj-rg9j is a medium-severity (CVSS 6.1) Cross-site Scripting (XSS) vulnerability in camaleon_cms. O3 Security confirms whether GHSA-x78v-4fvj-rg9j is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Camaleon CMS Stored Cross-site Scripting vulnerability
Real-World Exposure
camaleon_cmsReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects RubyGems packages — download data is not available via public APIs for these ecosystems.
Description
In “Camaleon CMS” application, versions 0.0.1 through 2.6.0 are vulnerable to stored XSS, that allows unprivileged application users to store malicious scripts in the comments section of the post. These scripts are executed in a victim’s browser when they open the page containing the malicious comment.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 💎RubyGems | camaleon_cms | ≥ 0.0.1&&< 2.6.0.1 | 2.6.0.1 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for camaleon_cms. 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 camaleon_cms to 2.6.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-x78v-4fvj-rg9j 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-x78v-4fvj-rg9j 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-x78v-4fvj-rg9j. 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-x78v-4fvj-rg9j in your dependencies?
O3 detects GHSA-x78v-4fvj-rg9j across RubyGems dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
