1. Discount oracle free membership redemption in the Paid Member Subscriptions plugin
Type of vulnerability: a chain of Information Disclosure (oracle) and bypassing the subscription business logic
Number of installations: 10,000
The seller claims that a combination of two vulnerabilities allows bypassing the verification and obtaining a paid membership for free in the paid subscriptions plugin, presumably Paid Member Subscriptions.

Type of vulnerability: bypassing the reCAPTCHA v3 bot protection
Number of installations: 10,000

According to the seller, the exploit completely bypasses the second factor.
4. Unauth full-user PII dump
Type of vulnerability: Unauthenticated Information Disclosure
Number of installations: 20,000
With a single unauthenticated GET request, the entire user table of the site is downloaded: email, phones, full name, logins (including administrators).
5. Blind SSRF via oEmbed
Type of vulnerability: Blind Server-Side Request Forgery
The exploit forces the server to send an HTTP request to an arbitrary URL, including internal and cloud-metadata endpoints (AWS IMDS, GCP metadata).
6. Unauth group-member enumeration
Type of vulnerability: Unauthenticated User Enumeration
Number of installations: 6,000
Without authorization, the composition of groups, sequential user IDs, logins, and the entire site database, including the administrator, are enumerated.

A single reverse call to the function completely disables the "logged-in only vs logged-out only" distinction in the plugin. It turns all protected endpoints into public ones.
