  script_tag(name:"insight", value:"The following issues exist:

  - Routes allow GET requests to override the HTTP method which breaks
    the Kallithea CSRF-protection (which only applies to POST requests).

    The attacker might misuse GET requests method overriding to trick users
    into issuing a request with a different method, thus bypassing the
    CSRF protection.

  - A vulnerability that allows logged-in users to edit or
    delete open pull requests associated with any repository to which
    they have read access, plus a related vulnerability allowing logged-in
    users to delete any comments from any repository, provided they could
    determine the comment ID and had read access to just one repository.");

  - to edit or delete open pull requests or delete comments by leveraging read access.

  - to bypass the CSRF protection by using the GET HTTP request method.");
