The Automation Web Platform - Notifications and OTP for WooCommerce, Advanced Country Code plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.8.6. This is due to missing permission enforcement on the publicly accessible REST route POST /wp-json/wawp/v1/signup/<op> and the absence of a key allowlist in the finish_registration_logic function, which copies the attacker-controlled wawp_custom_fields parameter directly into update_user_meta() - allowing sensitive meta keys such as wp_capabilities and wp_user_level to be set by the caller. This makes it possible for unauthenticated attackers to register a new account with the administrator role and gain full administrative access to the site. When OTP verification is enabled at signup, the OTP session token (otp_transient) is returned in plaintext in the HTTP response body, and the handle_magic_link_request() handler marks that token as verified on any unauthenticated GET request containing it without ever checking the OTP code value - making the OTP step trivially bypassable with no inbox or SMS access required.

AnalysisAI
Unauthenticated privilege escalation in the WordPress plugin Automation Web Platform - Notifications and OTP for WooCommerce, Advanced Country Code (all versions up to and including 4.8.6) allows any remote visitor to register a brand-new account holding the WordPress administrator role and take full control of the site. The publicly reachable signup REST route POST /wp-json/wawp/v1/signup/<op> performs no permission check and passes attacker-supplied wawp_custom_fields values straight into update_user_meta(), so keys such as wp_capabilities and wp_user_level can be set by the caller; when signup OTP is enabled, the plugin also leaks the otp_transient token in the HTTP response and marks it verified on any unauthenticated GET, so the OTP step can be skipped without any access to the victim's email or SMS. …

Vulnerability AssessmentAI
| Exploitation | No special conditions - remote unauthenticated exploitation against default configurations of the Automation Web Platform (Notifications and OTP for WooCommerce, Advanced Country Code) plugin ≤4.8.6, because the vulnerable REST route POST /wp-json/wawp/v1/signup/<op> is publicly accessible and the signup registration flow requires no authentication. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine top-priority vulnerability, not a high-CVSS-but-low-real-risk case. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No fixed release version is stated in the provided data, so the guiding signal is the upstream Trac changeset https://plugins.trac.wordpress.org/changeset?reponame=&old=3679350%40automation-web-platform&new=3679350%40automation-web-platform, which reflects the code change landed for this issue: treat the patched trunk state as the fix reference and upgrade the plugin to the first release published after that changeset, confirming release notes against https://www.wordfence.com/threat-intel/vulnerabilities/id/f17d3e43-29c6-4c80-912d-53ceda3fcb5d?source=cve before treating a build as remediated. … Detailed patch versions, workarounds, and compensating controls in full report. |
