CVE-2025-49300 identifies a vulnerability in the Traveler Option Tree plugin developed by shinetheme, specifically affecting versions up to 2.8. The issue involves the insertion of sensitive information into data sent by the plugin, which can lead to the retrieval of embedded sensitive data by unauthorized parties. The vulnerability is classified as an information disclosure flaw, impacting confidentiality without affecting data integrity or system availability. The CVSS 3.1 base score is 2.7, reflecting a low severity level. The attack vector is network-based (AV:N), with low attack complexity (AC:L), but requires high privileges (PR:H) and no user interaction (UI:N). This suggests that an attacker must already have elevated access to exploit the vulnerability, limiting its risk profile. No known exploits have been observed in the wild, and no patches are currently linked, indicating that mitigation may rely on vendor updates or configuration changes. The vulnerability could expose sensitive configuration or user data embedded within the plugin’s sent data, which may be leveraged for further attacks or data leakage. The plugin is commonly used in WordPress environments for managing custom options, so the exposure is limited to sites using this specific plugin version.

For European organizations, the primary impact is the potential leakage of sensitive information embedded within the Traveler Option Tree plugin’s data transmissions. While the vulnerability does not allow modification or disruption of services, the exposure of confidential data could lead to privacy violations, compliance issues (e.g., GDPR), and potential reconnaissance opportunities for attackers. The requirement for high privileges to exploit reduces the risk of external attackers but raises concerns if internal threat actors or compromised accounts exist. Organizations relying on this plugin for critical web applications or customer-facing portals may face reputational damage if sensitive data is exposed. The limited severity and absence of known exploits reduce immediate risk, but the vulnerability should be addressed promptly to prevent escalation or chained attacks.

1. Monitor the vendor’s official channels for patches addressing CVE-2025-49300 and apply updates promptly once available. 2. Restrict administrative and high-privilege access to the WordPress environment hosting the Traveler Option Tree plugin to trusted personnel only. 3. Implement network segmentation and firewall rules to limit external access to administrative interfaces and plugin endpoints. 4. Conduct regular audits of plugin configurations and data flows to detect any unauthorized data exposure. 5. Use web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin. 6. Consider disabling or replacing the Traveler Option Tree plugin if it is not essential or if no patch is available in a timely manner. 7. Educate internal users about the risks of privilege escalation and enforce strong authentication mechanisms to reduce the likelihood of compromised high-privilege accounts.
