Description
Grav Star Ratings 2.0.1 through 2.0.3 contains a missing authorization vulnerability that allows unauthenticated visitors to vote by bypassing client-only vote_access and readonly enforcement. Attackers can use the anonymous nonce emitted by getData() to submit votes directly to addVote(), manipulating restricted or disabled ratings and aggregate rating output.
