What is CVE-2024-11053?
CVE-2024-11053 is a low-severity vulnerability in Haxx Curl, published on 11 Dec 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
When asked to both use a `.netrc` file for credentials and to follow HTTP redirects, curl could leak the password used for the first host to the followed-to host under certain circumstances.
This flaw only manifests itself if the netrc file has an entry that matches the redirect target hostname but the entry either omits just the password or omits both login and password.
