CVE-2021-21278 (GCVE-0-2021-21278)

Vulnerability from cvelistv5 – Published: 2021-01-26 20:25 – Updated: 2024-08-03 18:09

Title

Risk of code injection in RSSHub

Summary

RSSHub is an open source, easy to use, and extensible RSS feed generator. In RSSHub before version 7f1c430 (non-semantic versioning) there is a risk of code injection. Some routes use `eval` or `Function constructor`, which may be injected by the target site with unsafe code, causing server-side security issues The fix in version 7f1c430 is to temporarily remove the problematic route and added a `no-new-func` rule to eslint.

Severity
