CVE-2026-9733

Beschreibung

Mojolicious::Plugin::Web::Auth::OAuth2 versions through 0.17 for Perl have an insecure default state parameter. When no state generator is specified in the constructor, the module defaults to using a SHA-1 hash of predictable and low-entropy sources, including the epoch time (which is leaked via the HTTP Date header) and a call to Perl-s built-in rand function. A predictable state allows an attacker to hijack another user-s session through cross site request forgery (CSRF).
