Active exploitation has been reported against CVE-2026-1492 in the User Registration & Membership WordPress plugin (WPEverest), allowing unauthenticated privilege escalation by submitting a user-controlled role value during membership registration. The flaw affects versions through 5.1.2 and enables attackers to create administrator accounts, which can then be used to install plugins/themes, modify PHP code and security settings, exfiltrate site/user data, and potentially implant malware or backdoors. Wordfence/Defiant telemetry cited in reporting indicates exploitation attempts were observed and blocked at scale in customer environments.
A fix was released in 5.1.3 (with 5.1.4 available), and the recommended mitigation is to update immediately or temporarily disable/uninstall the plugin if patching is not possible. Other WordPress plugin CVEs in the provided material—CVE-2026-1321 (Restrict Content unauth privilege escalation via rcp_level), CVE-2026-1720 (WowOptin missing authorization enabling Subscriber+ arbitrary plugin installation), and CVE-2026-2628 (All-in-One Microsoft 365 & Entra ID / Azure AD SSO Login authentication bypass)—are separate issues and should be tracked independently, as they do not describe the same exploited vulnerability affecting User Registration & Membership (CVE-2026-1492).

Multiple high-severity flaws in popular WordPress membership plugins can let attackers create administrator accounts and fully compromise affected sites. In the **User Registration & Membership** plugin, `CVE-2026-1492` affects versions through `5.1.2` and allows **unauthenticated** attackers to bypass authentication by abusing exposed nonce values, weak server-side validation, and legitimate AJAX functionality in membership workflows, including requests to `admin-ajax.php`. Researchers said successful exploitation can lead to malicious plugin installation, persistence, data theft, site defacement, and potential remote code execution; the issue is fixed in version `5.1.3`, and public exploit code is available. A separate cluster of vulnerabilities affects **WishList Member** through version `3.30.1`, where several missing authorization checks let **Subscriber-level or higher** users escalate privileges. `CVE-2026-6895` and `CVE-2026-6419` can expose the plugin's REST API Secret Key through AJAX actions, while `CVE-2026-6898` and `CVE-2026-6897` allow authenticated users to generate or modify that key and other plugin settings. With the API key, an attacker can create a membership level mapped to the WordPress administrator role, register a new admin account, and take over the site, extending a pattern of recurring authentication-bypass and privilege-escalation weaknesses previously seen in related membership plugin codebases.

Multiple high-severity vulnerabilities were disclosed across popular **WordPress plugins**, creating pathways to account takeover, privilege escalation, and sensitive data exposure. The most severe issue, **CVE-2025-15521** in *Academy LMS* (<= `3.5.0`), allows **unauthenticated administrator account takeover** because the plugin’s password update flow relies on a **publicly exposed WordPress nonce** as authorization rather than validating user identity; *Wordfence* reported observing exploitation attempts in the wild and blocking dozens of attacks in a 24-hour period. Additional disclosures affect other plugins with different exploitation prerequisites and impacts. **CVE-2026-0726** in *Nexter Extension – Site Enhancements Toolkit* (<= `4.4.6`) is an **unauthenticated PHP object injection** via `nxt_unserialize_replace`, but it requires a usable **POP chain** from another installed plugin/theme to reach file deletion, data theft, or code execution. **CVE-2025-15347** in *Creator LMS* (<= `1.1.12`) enables **authenticated (Contributor+)** attackers to update arbitrary WordPress options due to a missing capability check, potentially leading to privilege escalation or site compromise. **CVE-2025-14977** in *Dokan* (<= `4.2.4`) is an **IDOR** in the `/wp-json/dokan/v1/settings` REST endpoint that lets **authenticated (Customer+)** users read/modify other vendors’ settings, including changing PayPal payout emails and accessing bank/payment details, enabling fraud and sensitive information disclosure.

Two newly disclosed vulnerabilities in WordPress plugins can let attackers elevate privileges to **Administrator** by abusing improper handling of user profile metadata. `CVE-2026-4261` affects **Expire Users** through version `1.2.2`, where the `save_extra_user_profile_fields` function allows modification of the `on_expire_default_to_role` meta value; an authenticated attacker with **Subscriber-level access or higher** can exploit the flaw to gain full administrative control. The issue was classified as `CWE-862` and carries a high-severity `CVSS v3.1` score with the vector `AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H`. A second flaw, `CVE-2026-3629`, impacts **Import and export users and customers** through version `1.29.7` and can, under specific conditions, allow even **unauthenticated** attackers to become administrators. The plugin's `save_extra_user_profile_fields` logic fails to block sensitive keys such as `wp_capabilities` because `get_restricted_fields` does not restrict them, enabling a crafted registration request to assign elevated privileges when **"Show fields in profile"** is enabled and a previously imported CSV included a `wp_capabilities` column header. That vulnerability was classified as `CWE-269` with a `CVSS v3.1` vector of `AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H`.
