CVE-2025-11973 is an arbitrary file read vulnerability classified under CWE-73 (External Control of File Name or Path) found in the 简数采集器 plugin for WordPress, affecting all versions up to and including 2.6.3. The flaw resides in the __kds_flag functionality, which handles the importation of featured images. Authenticated attackers with administrator-level privileges can exploit this vulnerability to read arbitrary files on the hosting server by manipulating file path parameters. This can lead to exposure of sensitive information such as configuration files, credentials, or other private data stored on the server. The vulnerability does not require user interaction and has a CVSS 3.1 base score of 4.9, indicating medium severity. The attack vector is network-based with low attack complexity but requires high privileges (administrator access). There are no known public exploits or patches currently available, increasing the urgency for organizations to implement mitigations. The vulnerability impacts confidentiality but does not affect integrity or availability of the system. The plugin is developed by zhengdon and is used in WordPress environments, which are widely deployed globally including Europe.

For European organizations, this vulnerability poses a risk of sensitive data exposure on WordPress sites using the 简数采集器 plugin. Since exploitation requires administrator privileges, the threat is primarily from insider threats or compromised admin accounts. If exploited, attackers could access configuration files, database credentials, or other sensitive server files, potentially facilitating further attacks or data breaches. This could lead to regulatory compliance issues under GDPR due to unauthorized access to personal or confidential data. Organizations relying on WordPress for critical web services or e-commerce platforms could suffer reputational damage and operational disruptions if sensitive information is leaked. The medium severity score reflects moderate risk, but the impact on confidentiality is significant, especially for sectors handling sensitive customer or business data. The absence of known exploits reduces immediate risk but does not eliminate the threat, particularly as attackers may develop exploits over time.

European organizations should immediately audit their WordPress installations to identify the presence of the 简数采集器 plugin and verify its version. Until an official patch is released, restrict administrator access strictly to trusted personnel and enforce strong authentication mechanisms such as multi-factor authentication (MFA). Implement web application firewalls (WAF) with custom rules to detect and block suspicious requests targeting the __kds_flag parameter or unusual file path manipulations. Regularly monitor server logs for anomalous file access patterns indicative of exploitation attempts. Consider isolating WordPress environments and limiting file system permissions to reduce the impact of arbitrary file reads. Backup critical data securely and ensure incident response plans are updated to handle potential data exposure events. Stay informed on vendor updates for patches and apply them promptly once available. Additionally, conduct security awareness training for administrators to recognize phishing or social engineering attempts that could lead to credential compromise.
