Mojolicious before 0.999927 does not properly implement HMAC-MD5 checksums, which has unspecified impact and remote attack vectors.

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

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

A directory traversal flaw was found in Mojolicious [1]. Because Mojolicious did not unescape paths before processing them, a user could use it to view arbitrary files using '%2f' rather than '/' (for example: %2f..%2f). This has been corrected in upstream version 1.17 [2].
