CVE-2026-9733
Last modified
CVE-2026-9733 is a critical-severity vulnerability rated 9.1/10 on the CVSS scale. 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).. EPSS estimates a 0.34% chance of exploitation in the next 30 days.
