CVE-2025-53317 is a high-severity vulnerability affecting the AcmeeDesign WPShapere Lite WordPress plugin, specifically versions up to 1.4. The vulnerability is classified as a Cross-Site Request Forgery (CSRF) issue (CWE-352) that enables an attacker to perform unauthorized actions on behalf of an authenticated user. Exploitation of this CSRF flaw can lead to Stored Cross-Site Scripting (XSS), where malicious scripts are permanently injected into the plugin's data or settings. The CVSS 3.1 base score of 7.1 reflects a network attack vector with low attack complexity, no privileges required, but requiring user interaction (such as the victim visiting a malicious site). The scope is changed, indicating that the vulnerability affects resources beyond the initially vulnerable component. The impact includes low confidentiality, integrity, and availability losses, meaning attackers can potentially steal data, modify content, or disrupt service to some extent. The vulnerability arises because the plugin does not properly validate the origin of requests, allowing attackers to trick logged-in administrators or users with sufficient privileges into submitting crafted requests that inject malicious scripts. These scripts can persist in the plugin's configuration or output, leading to further exploitation such as session hijacking, privilege escalation, or malware distribution. No patches or fixes have been published yet, and no known exploits are reported in the wild, but the presence of stored XSS combined with CSRF significantly raises the risk profile. Given the widespread use of WordPress and the popularity of UI customization plugins like WPShapere Lite, this vulnerability poses a notable threat to websites using this plugin without mitigation.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on WordPress sites customized with WPShapere Lite. The stored XSS enabled by CSRF can lead to theft of user credentials, session tokens, or other sensitive information, compromising confidentiality. Integrity can be affected as attackers may modify website content or settings, potentially defacing sites or injecting malicious content that harms brand reputation. Availability impact, while rated low, could manifest through denial-of-service conditions caused by malicious scripts or administrative lockout. Organizations in sectors such as e-commerce, finance, healthcare, and government that use WordPress for public-facing or internal portals are at higher risk due to the sensitive nature of their data and regulatory requirements like GDPR. The vulnerability could also facilitate lateral movement within networks if attackers leverage stolen credentials or session data. Additionally, the requirement for user interaction means social engineering or phishing campaigns could be used to trigger exploitation, increasing the attack surface. The lack of a patch means organizations must rely on mitigations to reduce risk until a fix is available.

1. Immediately audit all WordPress sites for the presence of the WPShapere Lite plugin and identify versions up to 1.4. 2. Disable or remove the plugin if it is not essential to reduce attack surface. 3. Implement strict Content Security Policy (CSP) headers to limit the impact of stored XSS by restricting script execution sources. 4. Enforce multi-factor authentication (MFA) for all administrative accounts to reduce the risk of session hijacking. 5. Educate users and administrators about phishing and social engineering risks to prevent inadvertent triggering of CSRF attacks. 6. Monitor web server and application logs for unusual POST requests or changes to plugin settings indicative of exploitation attempts. 7. Use Web Application Firewalls (WAFs) with custom rules to detect and block CSRF and XSS attack patterns targeting the plugin endpoints. 8. Regularly back up website data and configurations to enable quick restoration in case of compromise. 9. Engage with the plugin vendor or community to track patch releases and apply updates promptly once available. 10. Consider deploying security plugins that add CSRF tokens and input validation to mitigate such vulnerabilities proactively.
