Description Preview
This CVE details a cross-site scripting (XSS) vulnerability in the WP-Picasa-Image WordPress plugin's picasa_upload.php file, affecting version 1.0 and earlier. By supplying a crafted value to the post_id parameter, a remote attacker can inject arbitrary JavaScript or HTML that is executed in the context of a victim’s browser, potentially leading to session hijacking, defacement, or credential theft. The vulnerability is exploitable through normal user interaction with the plugin and poses risk to WordPress sites using this plugin version.
Overview
The WP-Picasa-Image plugin for WordPress contains a cross-site scripting vulnerability in its picasa_upload.php component, enabling remote attackers to inject and execute arbitrary script or HTML via the post_id parameter. The flaw affects version 1.0 and earlier, making sites that use this plugin susceptible to client-side code execution when the affected parameter is manipulated by an attacker.
Remediation
- Update the WP-Picasa-Image plugin to a version that includes the fix, or remove/disable the plugin if no patched version is available.
- If upgrading is not feasible, disable the plugin entirely or restrict access to its upload functionality to mitigate exposure.
- Implement proper input validation and output escaping for the post_id parameter (e.g., validate as expected data type and encode output using WordPress escaping functions).
- Apply security controls such as a web application firewall (WAF) to block malicious input targeting post_id and enable input sanitization across the site.
- Keep WordPress core, themes, and all plugins up to date with the latest security patches.
- Run regular security scans, monitor logs for unusual activity, and consider a code review or patch when maintaining custom or third-party plugins.
