CVE-2026-8926
9.1
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
Summary
When asking curl to use a .netrc file to find credentials and at the same
time specifying a URL with a username (without a password), like
https://user@example.com/, curl could wrongly get and use the password for
another user set in the .netrc file for that host if such a one exists and
there is no match for the specified user.
