CVE-2026-22383: 
WordPress vulnerability analysis and mitigation

CVE-2026-22383 is an Authorization Bypass Through User-Controlled Key (IDOR) vulnerability in the Mikado-Themes PawFriends – Pet Shop and Veterinary WordPress Theme. It allows authenticated attackers with low privileges to exploit incorrectly configured access control security levels, potentially accessing or modifying resources they should not be authorized to interact with. The vulnerability affects PawFriends theme versions up to and including 1.3. It was published on February 20, 2026, and carries a CVSS v3.1 base score of 5.4 (Medium) (Feedly, Vulners).

The root cause is classified as CWE-639 (Authorization Bypass Through User-Controlled Key), commonly known as an Insecure Direct Object Reference (IDOR). An attacker with a low-privilege authenticated account can manipulate user-controlled keys or identifiers in requests to bypass access controls and interact with objects or data belonging to other users or restricted roles. The attack vector is network-based, requires low privileges, no user interaction, and low attack complexity, making it straightforward to exploit for any authenticated user (Feedly, Patchstack).

Successful exploitation results in limited but meaningful unauthorized access: attackers can read data they are not authorized to view (low confidentiality impact) and modify data or resources belonging to other users (low integrity impact), with no availability impact. The scope is unchanged, meaning exploitation is confined to the vulnerable WordPress theme's context. In a pet shop or veterinary site context, this could expose customer records, appointment data, or other user-specific content to unauthorized parties (Feedly).

No public proof-of-concept exploit code or active in-the-wild exploitation has been reported for CVE-2026-22383. The EPSS score is approximately 0.041%, indicating a low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Exploitation requires an authenticated account with at least low-level privileges on the affected WordPress site (Feedly).

1. Reconnaissance: Identify a WordPress site running the PawFriends theme version 1.3 or earlier by inspecting page source, theme metadata, or using tools like WPScan.
2. Obtain low-privilege account: Register or log in as a standard authenticated user (e.g., subscriber or customer) on the target WordPress site.
3. Identify object references: Browse the site's functionality (e.g., appointments, pet listings, user profiles) and capture HTTP requests containing user-controlled identifiers (e.g., id=123, user_id=456) using a proxy tool such as Burp Suite.
4. Manipulate the identifier: Modify the user-controlled key in the request to reference another user's object (e.g., change id=123 to id=124) and resend the request.
5. Access or modify unauthorized data: If the theme fails to validate that the requesting user owns the referenced object, the server returns or modifies the targeted resource, confirming the IDOR vulnerability (Feedly, Patchstack).

• Logs: WordPress access logs showing authenticated requests to theme-specific endpoints with sequentially or randomly enumerated object ID parameters (e.g., ?id=1, ?id=2, etc.) from a single user account in a short time window.
• Logs: Repeated HTTP 200 responses to requests for resources belonging to different user accounts from the same authenticated session.
• Network: Unusual patterns of authenticated GET or POST requests targeting PawFriends theme endpoints with varying object reference parameters from a single IP address.

Users should update the PawFriends – Pet Shop and Veterinary WordPress Theme to a version beyond 1.3 that addresses this vulnerability, once a patched release is made available by Mikado-Themes. In the interim, site administrators should consider restricting registration or limiting authenticated user roles if not required for site operation. Monitoring access logs for anomalous enumeration patterns of object identifiers can help detect exploitation attempts (Patchstack, Feedly).

The vulnerability received minor social media attention, with mentions on Mastodon and Bluesky via TheHackerWire shortly after disclosure in February 2026. No significant vendor statements or notable researcher commentary beyond the initial Patchstack disclosure have been identified (Feedly).
