CVE-2025-10486 is a vulnerability in the steadycontent Content Writer plugin for WordPress, present in all versions up to and including 3.6.8. The issue arises from the plugin's practice of logging sensitive information into files that are publicly accessible on the web server. This exposure allows unauthenticated attackers to retrieve sensitive data by directly accessing these log files via HTTP requests. The vulnerability is categorized under CWE-532, which pertains to the insertion of sensitive information into log files, a common security misconfiguration that can lead to information disclosure. The CVSS 3.1 base score of 5.3 reflects that the attack vector is network-based (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and affects confidentiality only (C:L), with no impact on integrity or availability. The vulnerability does not require authentication or user interaction, making it easier to exploit remotely. Although no public exploits have been reported yet, the presence of sensitive information in logs can include credentials, API keys, or personal data, which attackers can leverage for further attacks or data breaches. The plugin is widely used in WordPress environments focused on content creation and management, increasing the potential attack surface. The lack of available patches at the time of publication necessitates immediate mitigation efforts to prevent data leakage.

For European organizations, this vulnerability poses a significant confidentiality risk, especially for those relying on the steadycontent Content Writer plugin in their WordPress infrastructure. Exposure of sensitive information could lead to data breaches involving personal data, intellectual property, or authentication credentials, potentially violating GDPR and other data protection regulations. This could result in legal penalties, reputational damage, and financial losses. Organizations in sectors such as media, publishing, marketing, and e-commerce, which often use content management plugins, are particularly vulnerable. The ease of exploitation without authentication increases the likelihood of automated scanning and data harvesting by malicious actors. Additionally, the exposure of sensitive information could facilitate subsequent attacks like phishing, credential stuffing, or lateral movement within networks. The medium severity rating indicates a moderate but tangible risk that should not be overlooked, especially given the regulatory environment in Europe emphasizing data confidentiality.

European organizations should immediately audit their WordPress installations to identify the presence of the steadycontent Content Writer plugin and its version. Until an official patch is released, administrators should restrict access to log files by configuring web server rules (e.g., .htaccess for Apache or equivalent for Nginx) to deny public HTTP access to log directories or files. It is advisable to review and sanitize log content to remove any sensitive information that may have been recorded. Implementing file system permissions to limit access to logs only to trusted system users can reduce exposure. Monitoring web server logs for unusual access patterns to log files can help detect exploitation attempts. Organizations should also consider disabling or uninstalling the plugin if it is not essential or replacing it with a more secure alternative. Regular backups and incident response plans should be updated to address potential data exposure scenarios. Finally, organizations should stay alert for official patches or updates from the vendor and apply them promptly once available.
