Fluent Forms
Monthly
Subscription cancellation authorization bypass in the Fluent Forms WordPress plugin (all versions before 6.2.1) permits any authenticated low-privilege user to cancel subscriptions belonging to other site members by submitting a crafted request referencing a victim's subscription identifier. The plugin fails to verify that the requesting user owns the referenced subscription before processing the cancellation, a classic Insecure Direct Object Reference (IDOR) pattern. A public proof-of-concept is available via WPScan; no confirmed active exploitation campaign (CISA KEV) has been identified at time of analysis, and the CVSS base score of 3.1 reflects the limited, integrity-only impact.
