Kurz gesagt
- CVE-2020-11021 ist eine Schwachstelle (HOCH (CVSS 7.5)) in http-client (http-client project), @actions/http-client.
- Wahrscheinlichkeit einer Ausnutzung in den nächsten 30 Tagen (EPSS): 1.8%, höher als bei 78.4% aller Schwachstellen.
- Abhilfe: auf 1.0.8 oder neuer aktualisieren.
Description
Impact
If consumers of the http-client:
- make an http request with an authorization header
- that request leads to a redirect (302) and
- the redirect url redirects to another domain or hostname
The authorization header will get passed to the other domain.
Note that since this library is for actions, the GITHUB_TOKEN that is available in actions is generated and scoped per job with these permissions.
Patches
The problem is fixed in 1.0.8 at npm here. In 1.0.8, the authorization header is stripped before making the redirected request if the hostname is different.
Workarounds
None.
