GHSA-32gr-4cq6-5w5q
MEDIUMrsshub vulnerable to Cross-site Scripting via unvalidated URL parameters
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
Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
rsshubnpmDescription
Impact
When the URL parameters contain certain special characters, it returns an error page that does not properly handle XSS vulnerabilities, allowing for the execution of arbitrary JavaScript code.
Users who access the deliberately constructed URL are affected.
Patches
This vulnerability was fixed in version c910c4d28717fb860fbe064736641f379fab2c91. Please upgrade to this or a later version.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for rsshub. 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 rsshub to 1.0.0-master.c910c4d or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-32gr-4cq6-5w5q 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-32gr-4cq6-5w5q 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-32gr-4cq6-5w5q. 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-32gr-4cq6-5w5q in your dependencies?
O3 detects GHSA-32gr-4cq6-5w5q across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
