Deeper analysis
CVE-2025-23618 is a Cross-Site Request Forgery (CSRF) vulnerability in the Twitter Shortcode WordPress plugin developed by starise, which enables Stored Cross-Site Scripting (XSS). The flaw affects all versions of the plugin from unknown initial release through version 0.9 inclusive. It has been assigned a CVSS v3.1 base score of 7.1 (High), with vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L, and is associated with CWE-352 (Cross-Site Request Forgery).
A remote attacker requires no privileges and can exploit the vulnerability over the network with low attack complexity, though it demands user interaction such as tricking a victim into visiting a malicious page. Exploitation leverages CSRF to induce the storage of XSS payloads on the target site, changing the security scope to cross-origin and allowing script execution in the context of site users, potentially leading to low-level impacts on confidentiality, integrity, and availability, such as session hijacking or data theft for affected users.
