CVE-2025-69344 is a vulnerability classified under CWE-862 (Missing Authorization) found in the ThemeHunk Oneline Lite WordPress theme, versions up to 6.6. The issue arises from incorrectly configured access control security levels, allowing users with limited privileges (PR:L) to perform unauthorized actions that impact the integrity of the website. Specifically, the vulnerability does not require user interaction (UI:N) and can be exploited remotely over the network (AV:N). The scope is unchanged (S:U), meaning the impact is limited to the vulnerable component without affecting other system components. The CVSS 3.1 base score is 4.3, indicating a medium severity level primarily due to the integrity impact without confidentiality or availability consequences. The vulnerability could allow an attacker to modify theme settings or content in unauthorized ways, potentially defacing the site or injecting malicious content. No patches or known exploits are currently available, but the vulnerability is publicly disclosed and should be addressed promptly. The lack of authentication bypass means the attacker must have some level of access, but the low privilege requirement lowers the barrier to exploitation. This vulnerability is particularly relevant for WordPress sites using the Oneline Lite theme, which is popular among small to medium-sized websites for its simplicity and design features.

For European organizations, this vulnerability poses a risk primarily to the integrity of their WordPress-based websites using the ThemeHunk Oneline Lite theme. Unauthorized modifications could lead to defacement, misinformation, or injection of malicious content, potentially damaging brand reputation and user trust. While it does not directly compromise confidentiality or availability, integrity breaches can indirectly lead to phishing or malware distribution, increasing overall risk. Organizations in sectors such as e-commerce, media, and public services that rely on WordPress for their web presence are particularly vulnerable. The medium severity score reflects that exploitation requires some level of authenticated access, but the low privilege needed means insider threats or compromised low-level accounts could be leveraged. The absence of known exploits in the wild provides a window for mitigation, but the public disclosure increases the risk of future exploitation attempts. European data protection regulations like GDPR emphasize the importance of maintaining data integrity, so breaches could also have compliance implications.

To mitigate this vulnerability, European organizations should immediately review and tighten access controls on their WordPress installations, particularly restricting who can access and modify theme settings. Implement role-based access control (RBAC) to ensure only trusted administrators have permissions to manage themes. Regularly audit user accounts and remove or disable unnecessary low-privilege accounts that could be exploited. Monitor website content and theme configurations for unauthorized changes using file integrity monitoring tools or WordPress security plugins. Keep WordPress core, themes, and plugins updated and subscribe to vendor or security mailing lists for patch announcements. If possible, temporarily disable or replace the Oneline Lite theme until a patch is released. Employ web application firewalls (WAFs) to detect and block suspicious requests targeting theme management endpoints. Finally, conduct security awareness training for administrators to recognize and report suspicious activities promptly.
