CVE-2025-14455 is a security vulnerability classified under CWE-862 (Missing Authorization) affecting the WordPress plugin Image Photo Gallery Final Tiles Grid, versions up to and including 3.6.7. The core issue is that the plugin fails to properly verify whether a user is authorized to perform certain gallery management actions. Specifically, authenticated users with Contributor-level access or higher can bypass authorization controls and manipulate galleries created by any user, including administrators. This includes deleting galleries, modifying their content, or cloning them without proper permissions. The vulnerability is exploitable remotely over the network without requiring user interaction, and the attack complexity is low since only authenticated access at Contributor level is needed. The CVSS v3.1 base score is 5.4, indicating a medium severity with no confidentiality impact but partial integrity and availability impact. The flaw can lead to unauthorized content manipulation, potentially disrupting website operations and damaging data integrity. No patches or fixes are currently linked, and no known exploits are reported in the wild, but the risk remains significant for sites using this plugin. The vulnerability highlights the importance of robust authorization checks in WordPress plugins, especially those managing user-generated content.

The primary impact of this vulnerability is on the integrity and availability of gallery content managed by the affected plugin. An attacker with Contributor-level access can delete or modify galleries created by other users, including administrators, which could lead to data loss, defacement, or unauthorized content changes. This can disrupt website functionality, damage brand reputation, and require costly recovery efforts. Since the vulnerability does not affect confidentiality, sensitive data leakage is not a direct concern. However, the ability to alter or remove content without proper authorization can undermine trust in the website and its content management. Organizations relying on this plugin for image galleries face risks of internal misuse or exploitation by compromised Contributor accounts. The medium severity score reflects these impacts combined with the ease of exploitation and the scope of affected systems, which includes all WordPress sites using this plugin version. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once the vulnerability becomes widely known.

1. Immediate mitigation involves restricting Contributor-level user permissions or temporarily disabling the Image Photo Gallery Final Tiles Grid plugin until a patch is available. 2. Monitor user roles and audit Contributor accounts to ensure no unauthorized users have elevated access. 3. Implement strict role-based access controls (RBAC) and consider limiting gallery management capabilities to trusted roles only (e.g., Editors or Administrators). 4. Regularly back up gallery data and website content to enable recovery in case of unauthorized modifications or deletions. 5. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious gallery management requests from Contributor accounts. 6. Stay informed about vendor updates or patches and apply them promptly once released. 7. Conduct security reviews of all installed plugins to identify and remediate similar authorization issues proactively. 8. Educate site administrators and users about the risks of privilege escalation and the importance of strong authentication practices to prevent account compromise.
