Title

DevKit Pro <= 2.3.0 - Unauthenticated Authentication Bypass to Administrator Account Takeover via 'original_user_id' Cookie in Frontend Revert Switch Flow

Summary

The DevKit Pro plugin for WordPress is vulnerable to Authentication Bypass Leading to Administrator Account Takeover in all versions up to, and including, 2.3.0 This is due to the `revert_switch` handler trusting the attacker-controlled `original_user_id` cookie as the privileged identity: `verify_nonce_and_capability()` incorrectly checks the `manage_options` capability on the user identified by the cookie rather than on the actual requester via `current_user_can()`, while the switch-back form and a valid session-bound nonce are emitted publicly via `wp_footer` to any visitor — including unauthenticated users — whenever that cookie is present. This makes it possible for unauthenticated attackers to set the `original_user_id` cookie to any administrator's user ID, collect the rendered nonce, and POST it back to the `revert_switch` handler, causing `wp_set_auth_cookie()` to be called with the administrator's ID and granting the attacker a full administrator-level authenticated session and complete site takeover.

Severity

9.8 (Critical)

GHSA-XWFV-9J83-WFJ7

Vulnerability from github – Published: 2026-10-02 06:30 – Updated: 2026-10-02 06:30

Details

The DevKit Pro plugin for WordPress is vulnerable to Authentication Bypass Leading to Administrator Account Takeover in all versions up to, and including, 2.3.0 This is due to the revert_switch handler trusting the attacker-controlled original_user_id cookie as the privileged identity: verify_nonce_and_capability() incorrectly checks the manage_options capability on the user identified by the cookie rather than on the actual requester via current_user_can(), while the switch-back form and a valid session-bound nonce are emitted publicly via wp_footer to any visitor — including unauthenticated users — whenever that cookie is present. This makes it possible for unauthenticated attackers to set the original_user_id cookie to any administrator's user ID, collect the rendered nonce, and POST it back to the revert_switch handler, causing wp_set_auth_cookie() to be called with the administrator's ID and granting the attacker a full administrator-level authenticated session and complete site takeover.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
