Security Advisories (10)
Mojo::DOM did not correctly parse <script> tags.
Small sessions could be used as part of a brute-force attack to decode the session secret.
A bug in format detection can potentially be exploited for a DoS attack.
Mojo::UserAgent was not checking peer SSL certificates by default.
GET requests with embedded backslashes can be used to access local files on Windows hosts
Mojo::UserAgent::CookieJar leaks old cookies because of the missing host_only flag on empty domain.
Directory traversal on Windows
Context sensitivity of method param could lead to parameter injection attacks.
Mojolicious versions from 0.999922 for Perl uses a hard coded string, or the application's class name, as an HMAC session cookie secret by default. These predictable default secrets can be exploited by an attacker to forge session cookies. An attacker who knows or guesses the secret could compute valid HMAC signatures for the session cookie, allowing them to tamper with or hijack another user’s session.

Mojo::JSON versions before 9.47 for Perl allow memory exhaustion via unbounded recursion in the pure-Perl decoder. The pure-Perl decode path (`_decode_value` dispatching to `_decode_array` and `_decode_object`) recurses with no depth limit, so a small deeply nested JSON document can consume excessive memory. This path is the default when Cpanel::JSON::XS is not installed or `MOJO_NO_JSON_XS=1` is set; the Cpanel::JSON::XS fast path is not affected. Any caller that decodes an untrusted JSON body, for example `Mojo::Message::json` reached through `$c->req->json`, can exhaust process memory and cause denial of service.
