CVE-2025-62977 identifies a missing authorization vulnerability in the 百度站长SEO合集 (Baidu Webmaster SEO Suite) plugin, which supports push notifications to multiple search engines including Baidu, Shenma, Bing, and Toutiao. The flaw exists in versions up to and including 2.1.3, allowing unauthenticated remote attackers to access certain functionalities that are supposed to be protected by Access Control Lists (ACLs). This means that critical functions within the plugin can be invoked without proper permission checks, potentially exposing sensitive operations or data. The vulnerability is classified with a CVSS 3.1 base score of 5.3 (medium severity), reflecting that it can be exploited remotely over the network without any privileges or user interaction. The impact is limited to confidentiality loss, with no direct effect on integrity or availability. No known exploits have been reported in the wild, and no patches are currently linked, indicating that remediation may still be pending. The plugin is primarily used for SEO management and push notifications to multiple search engines, which could be leveraged by attackers to manipulate SEO data or gain unauthorized insights into site operations. The lack of authorization checks suggests a design or implementation flaw in the plugin’s access control mechanisms, which should be addressed by the vendor to prevent unauthorized access.

For European organizations, the primary impact of this vulnerability lies in the potential unauthorized access to SEO management functions that could lead to information disclosure or manipulation of search engine push data. While the direct confidentiality impact is limited, unauthorized access could enable attackers to gather sensitive operational data or disrupt SEO workflows, potentially affecting online visibility and reputation. Organizations relying on this plugin for managing search engine submissions, especially those targeting Chinese or multi-regional search engines, may face risks of data leakage or unauthorized configuration changes. Although the vulnerability does not affect integrity or availability directly, indirect impacts such as reputational damage or loss of trust from partners and customers could occur. The absence of known exploits reduces immediate risk, but the ease of exploitation without authentication means attackers could potentially probe for this vulnerability opportunistically. European companies with digital marketing operations involving Baidu or related platforms should consider this vulnerability a moderate risk, particularly if the plugin is exposed to the internet or used in multi-tenant environments.

1. Monitor the vendor’s official channels for patches or updates addressing CVE-2025-62977 and apply them promptly once available. 2. Until patches are released, restrict access to the 百度站长SEO合集 plugin’s administrative interfaces using network-level controls such as IP whitelisting or VPN access. 3. Implement web application firewall (WAF) rules to detect and block unauthorized attempts to access sensitive plugin functionality. 4. Conduct regular audits of user permissions and plugin configurations to ensure no excessive privileges are granted. 5. If feasible, isolate the plugin’s functionality on dedicated systems or containers to limit the blast radius of potential exploitation. 6. Monitor logs for unusual access patterns or unauthorized API calls related to the plugin. 7. Educate relevant staff about the risks of missing authorization vulnerabilities and encourage vigilance in plugin management. 8. Consider alternative SEO management tools with stronger security postures if immediate patching is not possible.
