CVE-2025-62150 is a security vulnerability identified in the Themesawesome History Timeline plugin, specifically versions up to 1.0.6. The root cause is a missing authorization check (CWE-862), meaning the plugin fails to properly verify whether a user has the necessary permissions before allowing certain actions. This flaw enables users with limited privileges (requiring some level of authentication) to perform unauthorized operations that can alter data integrity within the timeline feature. The vulnerability is exploitable remotely over the network without user interaction, and the attack complexity is low, making it relatively straightforward for an attacker with some access to exploit. The CVSS 3.1 base score is 4.3, reflecting a medium severity primarily due to the impact on integrity without affecting confidentiality or availability. No patches are currently linked, and no known exploits have been reported in the wild, indicating that while the vulnerability is recognized, active exploitation is not yet observed. The issue arises from incorrectly configured access control security levels, which is a common problem in web applications where authorization logic is not consistently enforced. This can lead to unauthorized modifications of timeline data, potentially misleading users or corrupting historical records displayed by the plugin. Since the plugin is used in WordPress environments, the exposure depends on the plugin’s deployment and user privilege configurations.

For European organizations, the primary impact of this vulnerability is the potential unauthorized modification of timeline data, which can affect data integrity and trustworthiness of displayed information. This could have reputational consequences, especially for organizations relying on accurate historical or event data presentation, such as news agencies, educational institutions, or corporate websites. While confidentiality and availability are not directly impacted, integrity loss can lead to misinformation or manipulation of content. Attackers with limited privileges could exploit this vulnerability to escalate their influence within the affected system, potentially leading to further attacks or data corruption. The medium CVSS score reflects that the threat is significant but not critical, and the lack of user interaction requirement increases the risk of automated exploitation. European organizations using WordPress with this plugin installed should be aware of the risk, especially if the plugin is exposed to authenticated users with limited roles. The absence of known exploits suggests a window of opportunity to remediate before widespread attacks occur.

1. Monitor Themesawesome’s official channels for patch releases addressing CVE-2025-62150 and apply updates promptly once available. 2. Until patches are released, restrict access to the History Timeline plugin features to only trusted and necessary user roles to minimize exposure. 3. Implement strict role-based access control (RBAC) within WordPress to ensure users have the minimum privileges required. 4. Conduct regular audits of user permissions and plugin configurations to detect and correct any misconfigurations. 5. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin’s endpoints. 6. Monitor logs for unusual activity related to timeline modifications, especially from users with limited privileges. 7. Educate administrators and developers about the importance of authorization checks and secure coding practices to prevent similar issues. 8. Consider temporarily disabling the plugin if it is not critical to operations until a secure version is available.
