How do I fix GHSA-hwpg-x5hw-vpv9?

Update changedetection-io to 0.50.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hwpg-x5hw-vpv9 is resolved across your whole dependency graph.

How do I detect GHSA-hwpg-x5hw-vpv9 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for changedetection-io, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-hwpg-x5hw-vpv9 if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is GHSA-hwpg-x5hw-vpv9 actively exploited in the wild?

No public exploit code has been indexed for GHSA-hwpg-x5hw-vpv9 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-hwpg-x5hw-vpv9?

GHSA-hwpg-x5hw-vpv9 has an EPSS (Exploit Prediction Scoring System) score of 0.6%, placing it in the 49th percentile of all CVEs.
