CVE-2025-58207 identifies a missing authorization vulnerability in the WP Messiah Ai Image Alt Text Generator for WordPress plugin, affecting versions up to and including 1.1.5. This vulnerability arises from incorrectly configured access control mechanisms that fail to properly restrict unauthenticated users from accessing sensitive plugin functionality or data. The vulnerability is remotely exploitable over the network without requiring any privileges or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). Successful exploitation results in a high impact on confidentiality, allowing attackers to retrieve sensitive information that should be protected by authorization checks. The integrity impact is low, and availability is not affected. The plugin is designed to generate alt text for images using AI, which may involve processing or storing sensitive metadata or content. The lack of authorization checks means that attackers can potentially access or manipulate this data without restriction. Although no known exploits are currently reported in the wild, the vulnerability's characteristics make it a significant risk. The issue was reserved in August 2025 and published in November 2025, with no patch links currently available, indicating that remediation may still be pending. Organizations using this plugin should consider the risk of data leakage and unauthorized access inherent in this vulnerability.

For European organizations, the primary impact of CVE-2025-58207 is the unauthorized disclosure of sensitive information managed or generated by the Ai Image Alt Text Generator plugin. This can lead to data breaches involving intellectual property, user data, or internal content metadata, potentially violating GDPR and other data protection regulations. The confidentiality breach could undermine trust in affected websites and lead to reputational damage. Since the vulnerability does not affect integrity or availability significantly, the risk of data tampering or service disruption is low. However, the ease of exploitation without authentication or user interaction increases the attack surface, especially for public-facing WordPress sites. Organizations relying on this plugin for accessibility or SEO improvements may face compliance issues if alt text data is exposed. The lack of patches at publication time means organizations must act quickly to mitigate exposure. Attackers could also use the vulnerability as a foothold for further attacks if sensitive configuration or environment details are leaked. Overall, the threat poses a significant risk to confidentiality and regulatory compliance for European entities using this plugin.

1. Immediately audit all WordPress sites for the presence of the WP Messiah Ai Image Alt Text Generator plugin and identify affected versions (<=1.1.5). 2. Disable or uninstall the plugin until an official patch or update is released by the vendor. 3. Monitor web server and application logs for unusual or unauthorized access attempts targeting the plugin endpoints. 4. Implement Web Application Firewall (WAF) rules to restrict access to plugin-specific URLs or functions, blocking unauthenticated requests where possible. 5. Review and tighten WordPress user roles and permissions to minimize exposure of sensitive plugin functionality. 6. Once a patch is available, apply it promptly and verify that authorization controls are correctly enforced. 7. Conduct penetration testing focused on access control mechanisms for all installed plugins to detect similar vulnerabilities. 8. Educate site administrators about the risks of installing plugins from unverified sources and the importance of timely updates. 9. Consider alternative plugins with better security track records for AI-based alt text generation if immediate patching is not feasible. 10. Maintain regular backups and ensure incident response plans include scenarios involving unauthorized data access via plugins.
