CVE-2026-94258 Details
Description
The SMS Alert WordPress plugin before 4.0.1 does not check that the acting administrator is allowed to manage the selected users before returning their stored billing phone numbers, allowing an administrator of one site on a multisite network to disclose the phone numbers of users who belong to other sites on that network. This affects multisite only, and requires the SMS Alert WordPress plugin before 4.0.1's gateway credentials to be stored on the acting administrator's own site.
A vulnerability in the SMS Alert WordPress plugin, affecting versions prior to 4.0.1, allows administrators on a multisite network to access and disclose the billing phone numbers of users from other sites. This issue arises because the plugin does not verify whether the acting administrator has the right to manage the selected users before retrieving their phone numbers. The vulnerability is only present in multisite installations where the plugin's gateway credentials are stored on the administrator's site.
Users are advised to update the SMS Alert WordPress plugin to version 4.0.1 or later.
