CVE-2026-22404: 
WordPress vulnerability analysis and mitigation

CVE-2026-22404 is an Authorization Bypass Through User-Controlled Key (IDOR) vulnerability in the Mikado-Themes Innovio WordPress theme. It allows attackers to exploit incorrectly configured access control security levels, affecting Innovio versions up to and including 1.7. The vulnerability was disclosed on January 22, 2026, with Patchstack as the reporting CNA. It carries a CVSS v3.1 base score of 3.8 (Low), as assessed by Patchstack (Patchstack).

The vulnerability is classified as CWE-639 (Authorization Bypass Through User-Controlled Key), commonly known as an Insecure Direct Object Reference (IDOR). An attacker can manipulate user-controlled keys or identifiers in requests to bypass access controls and access or modify resources they are not authorized to interact with. Exploitation requires network access and high privileges (PR:H per the CVSS vector), limiting the practical attack surface. No public technical write-up or proof-of-concept code has been identified beyond the Patchstack advisory (Patchstack).

Successful exploitation results in limited confidentiality and integrity impacts — an authenticated high-privileged attacker could access or modify data objects they should not be authorized to interact with. There is no availability impact. The scope is unchanged, meaning exploitation is confined to the vulnerable WordPress theme component without lateral movement potential beyond the application layer (Patchstack).

No public proof-of-concept exploit code or evidence of in-the-wild exploitation has been identified for CVE-2026-22404. The EPSS score is approximately 0.017% (0.000170), indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. The requirement for high privileges further reduces the likelihood of opportunistic exploitation.

Users of the Innovio WordPress theme by Mikado-Themes should update to a version beyond 1.7 if a patched release is available from the vendor. If no patch is yet available, site administrators should restrict access to sensitive theme functionality and audit user privilege assignments to minimize exposure. Monitoring WordPress admin logs for unexpected access to protected resources is also advisable (Patchstack).
