Infinite recusrion on captcha script

hello, noticed that arachni is unable to avoid scanning recursive elements, such as captcha script. I've tried with option --scope-auto-redundant=2 but it didn't work.
Link example:,255,255&bgr=196,196,196&xsize=100&ysize=40&suf=1
Dynamic values are marked by me as "(DYNAMIC)"

If you need more information (domain/log/etc) please tell me your email and i'll send it to you

    Looks like a parameter name (1486894932(DYNAMIC)) is dynamic, so the --scope-auto-redundant option will not work.
    You can use the --scope-redundant-path-pattern option for greater control, like so:


    Let me know how it works.

    showcode.php:10 worked well, is there any chance to add a plugin for autosolving such problems without user actions?

    Can't really be done accurately.
