Helpfulcrowd Product Reviews
Monthly
Unauthenticated settings manipulation in Helpfulcrowd Product Reviews plugin for WordPress (versions up to and including 1.2.9) allows any remote attacker to overwrite arbitrary plugin configuration values in the WordPress database. The vulnerability stems from a PHP type juggling flaw in the token validation function combined with an openly accessible REST endpoint registered with `__return_true` as its permission callback. By submitting a JSON boolean `true` as the token value, an attacker bypasses the loose-comparison check (`!=`) in `helpfulcrowd_validate_token()` and gains full write access to the `helpfulcrowd_options` database option with no sanitization or allowlist enforcement. No public exploit or CISA KEV listing is identified at time of analysis.
