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.

5 events from the most recent confirmed update back to the earliest known activity.
Four high-severity vulnerabilities affecting WishList Member for WordPress up to version 3.30.1 were disclosed, all enabling Subscriber-level users to obtain or modify the plugin's REST API Secret Key and escalate privileges to administrator. The issues involved the wlm3_export_settings, wlm3_get_screen, wlm3_generate_api_key, and wishlistmember_team_accounts_save_settings AJAX actions.
CYFIRMA published technical analysis of CVE-2026-1492, describing direct role manipulation during registration and abuse of /wp-admin/admin-ajax.php membership workflows. The report also noted public exploit availability and observed underground interest in the vulnerability.
The vendor addressed CVE-2026-1492 by releasing version 5.1.3 of the User Registration & Membership plugin. The fix remediated the server-side validation and authorization weaknesses enabling admin account creation and site compromise.
A critical authentication bypass and privilege escalation flaw affecting the WordPress User Registration & Membership plugin up to version 5.1.2 was published. The issue allowed unauthenticated attackers to abuse AJAX membership workflows and potentially gain administrator access.
A GitHub repository for CVE-2025-2594 describing an authentication bypass in the WordPress User Registration & Membership plugin was published, indicating public exploit or proof-of-concept availability for that earlier issue.

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 WordPress plugins exposed sites to account takeover and, in one case, possible remote code execution. In **Users Manager PN**, tracked as `CVE-2026-4003`, a missing authorization check in the `userspn_ajax_nopriv_server()` handler let unauthenticated attackers overwrite arbitrary user metadata through the `userspn_form_save` AJAX action. Because the required `userspn-nonce` was reportedly exposed on public pages, attackers could abuse the bug with a single crafted request to modify profiles and potentially seize control of administrator accounts. The issue affected versions through `1.1.15` and was reportedly fixed in `1.1.20`. Two additional vulnerabilities were disclosed in **WP Captcha PRO** affecting versions through `5.38`. `CVE-2026-5415` allowed **Subscriber-level users or higher** to generate temporary login links for arbitrary accounts because the `ajax_run_tool()` AJAX handler checked only a nonce and not user capabilities, enabling authentication bypass and administrator takeover. Separately, `CVE-2026-5411` allowed authenticated low-privilege users to upload attacker-controlled files by poisoning license metadata and abusing `sync_cloud_protection()` to download and extract content into a web-accessible uploads directory; if PHP execution was possible and `allow_url_fopen` was enabled for remote retrieval, the flaw could be escalated to **remote code execution** via a webshell.

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.
