CVE-2025-48325 is a high-severity security vulnerability classified as CWE-352, which corresponds to Cross-Site Request Forgery (CSRF), found in the shmish111 WP Admin Theme for WordPress. This vulnerability allows an attacker to perform unauthorized actions on behalf of an authenticated user by exploiting the lack of proper CSRF protections in the theme. Specifically, the vulnerability enables Stored Cross-Site Scripting (Stored XSS) attacks, where malicious scripts injected by the attacker are persistently stored on the target system and executed in the context of the victim's browser. The affected product is the WP Admin Theme by shmish111, with versions up to 1.0 impacted, although exact version details are not specified. The CVSS v3.1 base score is 7.1, indicating a high severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L) reveals that the attack can be executed remotely over the network without privileges and with low attack complexity, but requires user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact affects confidentiality, integrity, and availability at a low level each. The vulnerability arises because the theme does not implement adequate anti-CSRF tokens or mechanisms, allowing attackers to craft malicious web requests that, when visited by an authenticated administrator or user, execute unauthorized commands or inject persistent malicious scripts. This can lead to session hijacking, data theft, defacement, or further compromise of the WordPress installation. No patches are currently linked, and no known exploits are reported in the wild as of the publication date (August 28, 2025).

For European organizations using the shmish111 WP Admin Theme, this vulnerability poses a significant risk to the security of their WordPress-based websites or administrative portals. Exploitation could lead to unauthorized changes in site content, theft of sensitive user data, or persistent malware injection, potentially damaging organizational reputation and violating data protection regulations such as GDPR. The stored XSS component can facilitate session hijacking or privilege escalation, enabling attackers to pivot within the network or conduct further attacks. Given the theme is an administrative interface component, compromise could lead to full site control. This is particularly impactful for organizations relying on WordPress for critical web services, e-commerce, or customer interaction. The requirement for user interaction means phishing or social engineering could be used to lure administrators into triggering the exploit. The lack of known exploits currently provides a window for proactive mitigation, but the low attack complexity and remote network vector make this a pressing concern.

European organizations should immediately audit their WordPress installations to identify the use of the shmish111 WP Admin Theme. If present, they should restrict administrative access via network-level controls such as VPNs or IP whitelisting to reduce exposure. Implementing Web Application Firewalls (WAFs) with custom rules to detect and block CSRF attack patterns and suspicious POST requests targeting the theme's endpoints can provide interim protection. Administrators should be trained to recognize phishing attempts to prevent inadvertent triggering of malicious requests. Until an official patch is released, consider disabling or replacing the vulnerable theme with a secure alternative. Additionally, enabling Content Security Policy (CSP) headers can help mitigate the impact of stored XSS by restricting script execution. Regular backups and monitoring for anomalous administrative actions or injected scripts are essential for early detection and recovery. Organizations should subscribe to vendor and security advisories for timely patch updates.
