Context sensitivity of method param could lead to parameter injection attacks.

CVE-2011-1589 (2011-04-05)

Directory traversal vulnerability in Path.pm in Mojolicious before 1.16 allows remote attackers to read arbitrary files via a %2f..%2f (encoded slash dot dot slash) in a URI.

CVE-2010-4802 (2011-05-03)

Commands.pm in Mojolicious before 0.999928 does not properly perform CGI environment detection, which has unspecified impact and remote attack vectors.

CVE-2011-1841 (2011-03-10)

Cross-site scripting (XSS) vulnerability in the link_to helper in Mojolicious before 1.12 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

CVE-2024-58134 (2025-05-03)

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.

CVE-2026-14803 (2026-07-06)

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.
