CVE-2025-69030: 
WordPress vulnerability analysis and mitigation

CVE-2025-69030 is an Insecure Direct Object Reference (IDOR) / Authorization Bypass Through User-Controlled Key vulnerability in the Mikado-Themes Backpack Traveler WordPress theme. It affects all versions up to and including 2.10.3, allowing authenticated attackers with low privileges (Subscriber-level) to bypass access controls. The vulnerability was reported on November 29, 2025, by Tran Nguyen Bao Khanh (VCI - VNPT Cyber Immunity) and published on December 29–30, 2025. It carries a CVSS v3.1 base score of 5.4 (Medium) (Patchstack).

The vulnerability is classified as CWE-639 (Authorization Bypass Through User-Controlled Key), commonly known as IDOR. The root cause is incorrectly configured access control within the Backpack Traveler WordPress theme, where object references (such as IDs or keys) supplied by the user are not properly validated against the authenticated user's authorization level. An attacker with at least Subscriber-level access can manipulate these user-controlled keys in requests to access or modify resources they should not be permitted to interact with. No public proof-of-concept exploit code has been identified at this time (Patchstack).

Successful exploitation could allow a low-privileged authenticated attacker to bypass authorization controls, potentially accessing sensitive files, folders, or database records belonging to other users or restricted areas of the WordPress site. The integrity and availability impacts are rated low, with no direct confidentiality impact per the CVSS scoring, though IDOR vulnerabilities can expose sensitive data depending on the specific objects accessible. The scope is limited to the affected WordPress installation running the vulnerable theme (Patchstack).

The vulnerability requires low-level authentication (Subscriber role) and no user interaction, making it relatively straightforward to exploit for any registered user on an affected WordPress site. The EPSS score is 0.017% (0.000170), indicating a very low probability of exploitation in the wild at this time. No in-the-wild exploitation, threat actor attribution, or CISA KEV catalog listing has been identified. No official patch is currently available as of the publication date (Patchstack).

1. Reconnaissance: Identify WordPress sites using the Backpack Traveler theme version 2.10.3 or earlier, using tools like WPScan or by inspecting theme metadata in page source.
2. Obtain low-privilege access: Register or obtain a Subscriber-level account on the target WordPress site.
3. Identify object references: Browse the site's functionality exposed by the Backpack Traveler theme and capture HTTP requests containing object identifiers (e.g., post IDs, user IDs, or resource keys) using a proxy tool such as Burp Suite.
4. Manipulate object references: Modify the user-controlled key parameters in captured requests to reference objects belonging to other users or restricted resources.
5. Access unauthorized resources: Submit the manipulated requests and observe whether the server returns data or performs actions on resources that should be restricted, achieving unauthorized access or modification (Patchstack).

• Logs: WordPress access logs showing authenticated requests (Subscriber-level users) accessing admin-only or other users' resources via theme-specific endpoints with sequential or enumerated ID parameters.
• Network: Repeated HTTP requests to theme-specific URLs with incrementing or modified object reference parameters from a single low-privilege user account.
• Logs: Unusual patterns of access to WordPress database-backed resources (posts, user data) by accounts that should not have such permissions, visible in server access logs or WordPress audit log plugins.

As of the disclosure date (December 29, 2025), no official patch is available for the Backpack Traveler theme. Site administrators are advised to monitor the theme's official repository or the WordPress theme directory for an updated version and apply it as soon as one is released. In the interim, consider restricting user registration to trusted individuals, disabling open registration if not required, or using a Web Application Firewall (WAF) with IDOR detection rules. Patchstack users may benefit from virtual patching capabilities offered by the platform (Patchstack).
