    Are you reporting this as an issue with version 2.3.1patch4? Lighthouse tends to mangle tags in posts, but we are unable to reproduce this anomaly in v2.3.1patch4 (the current release).

    • Only a logged-in admin user could run this command (userperms) so the parameters wouldn't be acted on
    • We show only normal activity when adding a double quote, followed by an opening script tag, followed by 'alert(7);', followed by a closing script tag. (the payload is stripped out)

    If you are able to get this to occur in v2.1.4patch6, v2.2.3patch9, or v2.3.1patch4, please provide more details or a confirmation of my description of your specific url additions.

    The version release package and the patches can be found at either of these locations:

    Current version is v2.3.1patch4 (install v2.3.1 followed by v2.3.1patch4)

    Patches were released for two older versions (latest release prior to a major update)
    v2.2.3patch9 (install v2.2.3 followed by v2.2.3patch9)
    v2.1.4patch6 (install v2.1.4 followed by v2.1.4patch6)
