CVE-2025-62977 identifies a Missing Authorization vulnerability in the 百度站长SEO合集 (Baidu Webmaster SEO Suite) plugin, which integrates push notification capabilities for multiple search engines including Baidu, Shenma, Bing, and Toutiao. The vulnerability arises because certain functions within the plugin are not properly constrained by Access Control Lists (ACLs), allowing unauthorized users to invoke functionality that should be restricted. This could enable attackers to perform actions such as unauthorized data submission, manipulation of SEO-related configurations, or triggering push notifications without permission. The affected versions include all releases up to and including 2.1.3, with no patch currently available. The vulnerability was published on October 27, 2025, and no known exploits have been detected in the wild so far. The lack of authorization checks means that an attacker does not need valid credentials or elevated privileges to exploit the flaw, increasing the risk. Since the plugin is used primarily for SEO management targeting Chinese and other Asian search engines, organizations leveraging this tool for their web presence are at risk of unauthorized interference, which could degrade their SEO effectiveness or expose sensitive operational data. The absence of a CVSS score requires an assessment based on the potential impact on confidentiality, integrity, and availability, the ease of exploitation, and the scope of affected systems.

For European organizations, the impact of this vulnerability could be significant, particularly for those engaged in digital marketing or SEO activities targeting Chinese or Asian markets. Unauthorized access to the plugin’s functionality could lead to manipulation of SEO data, unauthorized push notifications, or disruption of search engine indexing processes. This may result in reputational damage, loss of competitive advantage, or exposure of sensitive business strategies. Additionally, if the plugin is integrated into broader content management or web infrastructure, attackers might leverage this vulnerability as a foothold for further compromise. The absence of authentication requirements lowers the barrier for exploitation, increasing the likelihood of attacks. Given the strategic importance of maintaining effective SEO and web presence, especially for companies operating internationally, this vulnerability poses a tangible risk to confidentiality and integrity of SEO operations and potentially availability if the plugin is misused to disrupt services.

1. Immediately restrict access to the 百度站长SEO合集 plugin’s administrative interfaces to trusted personnel only, using network segmentation or IP whitelisting. 2. Monitor logs and audit trails for unusual or unauthorized activity related to the plugin’s functions. 3. Implement web application firewalls (WAFs) with custom rules to detect and block unauthorized attempts to access the vulnerable functionality. 4. Engage with the plugin vendor or community to obtain patches or updates addressing this vulnerability as soon as they become available. 5. If patching is delayed, consider disabling the plugin temporarily or removing it if it is not critical to operations. 6. Conduct security reviews of all third-party SEO tools and plugins to ensure proper authorization controls are in place. 7. Educate relevant staff about the risks associated with unauthorized access to SEO management tools and enforce strict access control policies.
