Summary Serveral Server-Side Request Forgery (SSRF) vulnerabilities in RSSHub allow remote attackers to use the server as a proxy to send HTTP GET requests to arbitrary targets and retrieve information in the internal network or conduct Denial-of-Service (DoS) attacks.

# Patch Next advisory brief: CVE-2024-27927

Advisory: RSSHub vulnerable to Server-Side Request Forgery
IDs: CVE-2024-27927, GHSA-3p3p-cgj7-vgw3
Record: https://patchnext.com/advisories/cve-2024-27927 (revision 2, source checked 26 Oct 2026, 12:30 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: rsshub 1.0.0-master.a429472. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm rsshub: affected < 1.0.0-master.a429472; fixed in 1.0.0-master.a429472

## Suggested inspection (read-only)
- `npm ls rsshub --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on rsshub.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://osv.dev/vulnerability/GHSA-3p3p-cgj7-vgw3 (OSV record GHSA-3p3p-cgj7-vgw3 lists affected ranges: npm rsshub >=0 <1.0.0-master.a429472 (fixed))
