CVE-2025-11997 identifies an information exposure vulnerability in the Document Pro Elementor – Documentation & Knowledge Base plugin for WordPress, affecting all versions up to and including 1.0.9. The root cause is the insecure handling of Algolia API keys, which are embedded in frontend JavaScript code through the WordPress function wp_localize_script without proper access controls. This results in sensitive API keys being visible in the page source to any visitor, including unauthenticated attackers. Algolia API keys typically grant access to search services and may allow querying or modifying search indices depending on their permissions. Exposure of these keys can lead to unauthorized API calls, potentially enabling attackers to extract sensitive search data, manipulate search results, or incur service costs. The vulnerability is classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). The CVSS v3.1 base score is 5.3 (medium severity), reflecting that the attack vector is network-based, requires no privileges or user interaction, and impacts confidentiality but not integrity or availability. No patches or fixes are currently published, and no known exploits have been reported in the wild. The vulnerability affects all plugin versions up to 1.0.9, indicating that upgrading to a fixed version (when available) is critical. The exposure arises from frontend code, making detection straightforward by inspecting page source for API keys. Organizations using this plugin with Algolia integration should assess their exposure and take immediate steps to mitigate risk.

For European organizations, this vulnerability poses a risk of unauthorized access to Algolia search services integrated into their WordPress sites. Exposure of API keys can lead to data leakage if sensitive search indices contain confidential information. Attackers could also abuse the API to perform excessive queries, potentially leading to increased costs or service disruption. Although the vulnerability does not allow direct modification of site content or compromise of the WordPress environment, the confidentiality of search data is at risk. Organizations in sectors such as finance, healthcare, or government that use Document Pro Elementor with Algolia may face compliance issues under GDPR if personal or sensitive data is exposed. The ease of exploitation (no authentication or user interaction required) increases the likelihood of opportunistic attacks. However, the impact is somewhat limited by the scope of the API keys’ permissions and the nature of the data indexed by Algolia. Monitoring and restricting API key capabilities can reduce potential damage. Overall, the vulnerability could undermine trust in affected websites and expose organizations to reputational and regulatory risks.

1. Immediately audit all Algolia API keys exposed via the Document Pro Elementor plugin and rotate any keys found in frontend code. 2. Restrict Algolia API key permissions to the minimum necessary, ideally using search-only keys with limited query capabilities and no write or admin rights. 3. Monitor Algolia API usage logs for unusual or excessive queries that may indicate abuse. 4. Remove or replace the vulnerable plugin version with an updated version once a patch is released by the vendor. 5. If a patch is not yet available, consider disabling the plugin or removing Algolia integration temporarily. 6. Implement Content Security Policy (CSP) headers to limit JavaScript execution sources and reduce risk of key exposure through injected scripts. 7. Educate development teams on secure handling of API keys, avoiding embedding sensitive keys in frontend code. 8. Conduct regular security reviews of WordPress plugins, especially those handling third-party integrations. 9. Use web application firewalls (WAFs) to detect and block suspicious API calls targeting Algolia endpoints. 10. Engage with the plugin vendor to expedite patch development and disclosure.
