Details

wpDiscuz before 7.6.47 contains a vote manipulation vulnerability that allows attackers to manipulate comment votes by obtaining fresh nonces and bypassing rate limiting through client-controlled headers. Attackers can vary User-Agent headers to reset rate limits, request nonces from the unauthenticated wpdGetNonce endpoint, and vote multiple times using IP rotation or reverse proxy header manipulation.

Severity ?
