CVE-2026-22407: 
WordPress vulnerability analysis and mitigation

CVE-2026-22407 is an Authorization Bypass Through User-Controlled Key (IDOR) vulnerability in the Mikado-Themes Roam WordPress theme. It allows attackers to exploit incorrectly configured access control security levels by manipulating user-controlled keys to access or modify resources they should not be authorized to reach. The vulnerability affects all versions of the Roam theme up to and including 2.1.1. It was disclosed on January 22, 2026, with Patchstack as the assigning CNA. The CVSS v3.1 base score is 3.8 (Low), as assessed by Patchstack (Feedly, Patchstack).

The vulnerability is classified as CWE-639 (Authorization Bypass Through User-Controlled Key), commonly known as an Insecure Direct Object Reference (IDOR). The root cause is that the Roam theme fails to properly validate whether an authenticated user is authorized to access or manipulate a specific object when a user-controlled key (such as a post ID or resource identifier) is supplied in a request. Exploitation requires network access and high-privilege authentication (PR:H), meaning the attacker must already hold an elevated account on the WordPress installation. No public proof-of-concept code has been identified at this time (Feedly, Patchstack).

Successful exploitation results in limited confidentiality and integrity impacts — an attacker with high privileges can read or modify data objects they should not have access to, but availability is unaffected and the scope remains unchanged. The vulnerability does not enable remote code execution or privilege escalation on its own, limiting the blast radius to unauthorized data access or modification within the WordPress environment. The risk of lateral movement or significant data exposure is low given the high-privilege prerequisite (Feedly).

No public exploit code or active in-the-wild exploitation has been reported for CVE-2026-22407. The EPSS score is approximately 0.017%, indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. No threat actor attribution has been identified (Feedly).

WordPress site administrators using the Roam theme by Mikado-Themes should update to a version beyond 2.1.1 if a patched release is available from the theme vendor. If no patch is yet available, consider temporarily deactivating the theme or restricting high-privilege account access to trusted users only. Monitor the Patchstack advisory and the Mikado-Themes official channels for patch release announcements (Patchstack).
