Karma inflation via faulty prior-vote lookup
Published Jan 7, 2023 · Updated Aug 6, 2024
Improper access control in Koroket RedditOnRails Vote Handler allows remote authenticated users to inflate account karma through repeat voting. The post and comment controllers query post_id or comment_id instead of the polymorphic votable_id, so repeat requests evade the prior-vote lookup while still adding karma. A valid account and network access to the voting action are required; the demonstrated consequence is unauthorized karma manipulation, not account takeover.
