CVE-2025-49408 is a medium-severity vulnerability identified in the WPDeveloper Templately plugin, specifically affecting versions up to 3.2.7. The vulnerability is categorized under CWE-201, which involves the insertion of sensitive information into sent data. This means that the plugin inadvertently includes sensitive or confidential data within communications or data transmissions, which can then be retrieved by an attacker. The CVSS v3.1 score of 4.9 reflects a medium risk level, with the vector indicating that the attack can be performed remotely (AV:N), requires low attack complexity (AC:L), but does require high privileges (PR:H) and no user interaction (UI:N). The impact primarily affects confidentiality (C:H), with no impact on integrity or availability. Essentially, an attacker with high privileges on the system can exploit this vulnerability to extract embedded sensitive information that should not be exposed, potentially leading to data leaks or unauthorized disclosure of confidential information. The vulnerability does not currently have known exploits in the wild, and no official patches have been linked yet. The affected product, Templately, is a WordPress plugin used for template management and sharing, which is widely used by website developers and administrators to streamline design workflows.

For European organizations, this vulnerability poses a risk of sensitive data leakage if the Templately plugin is used within their WordPress environments. Since the vulnerability requires high privileges to exploit, it is most dangerous in scenarios where an attacker has already gained elevated access, such as through compromised administrator accounts or insider threats. The exposure of sensitive information could include configuration details, user data, or proprietary design assets, which might lead to further exploitation or reputational damage. Given the stringent data protection regulations in Europe, such as GDPR, any unauthorized disclosure of personal or sensitive data could result in significant legal and financial consequences. Organizations relying on Templately for website management should be aware that this vulnerability could be leveraged as part of a broader attack chain, especially in environments where privilege escalation has already occurred.

To mitigate this vulnerability, European organizations should first verify if they are using the Templately plugin and identify the version in use. Immediate steps include restricting administrative access to trusted personnel and implementing strong authentication mechanisms to prevent privilege escalation. Since no official patch is currently available, organizations should consider temporarily disabling the plugin or limiting its functionality until a fix is released. Monitoring and auditing logs for unusual access patterns or data exfiltration attempts related to Templately is critical. Additionally, organizations should enforce the principle of least privilege, ensuring that users have only the necessary permissions. Employing web application firewalls (WAFs) with custom rules to detect anomalous requests targeting Templately endpoints can provide an additional layer of defense. Finally, staying updated with vendor advisories and applying patches promptly once available is essential to fully remediate the risk.
