Deeper analysis

CVE-2025-30550 is a Cross-Site Request Forgery (CSRF) vulnerability in the WPShop.ru CallPhone'r WordPress plugin, also known as callphoner, that enables Stored XSS. This issue affects the plugin from unknown initial versions through version 1.1.1 inclusive. The vulnerability is classified under CWE-352 and carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L).

The vulnerability can be exploited by unauthenticated attackers accessible over the network, with low attack complexity but requiring user interaction, such as clicking a malicious link. Successful exploitation changes the scope to cross-origin (S:C), allowing limited impacts on confidentiality, integrity, and availability through the resulting Stored XSS, such as potential script execution in the context of the targeted user's browser.
