CVE-2026-32404: 
WordPress vulnerability analysis and mitigation

CVE-2026-32404 is a Missing Authorization (Broken Access Control) vulnerability in the Studio99 WP Monitor WordPress plugin. It affects all versions up to and including 1.0.3, allowing unauthenticated remote attackers to exploit incorrectly configured access control security levels. The vulnerability was reported on January 22, 2026, by researcher Nabil Irawan and published by Patchstack on February 21, 2026. It carries a CVSS v3.1 base score of 5.3 (Medium) (Patchstack).

The root cause is classified as CWE-862 (Missing Authorization), meaning the plugin fails to perform adequate authorization checks before executing certain privileged actions. An unauthenticated remote attacker can send crafted network requests to trigger functionality that should be restricted to higher-privileged users, exploiting the absence of proper capability checks, authentication verification, or nonce token validation. No special preconditions — such as an existing account or specific server configuration — are required for exploitation (Patchstack).

Successful exploitation results in a limited confidentiality impact, as reflected in the CVSS score (C:L/I:N/A:N), with no direct integrity or availability consequences. An unauthenticated attacker could access information or functionality intended for privileged users, potentially exposing monitoring data managed by the plugin. The scope is limited to the affected WordPress installation, with no evidence of lateral movement potential beyond the plugin's own functionality (Patchstack).

No public proof-of-concept exploit code or in-the-wild exploitation has been reported for this vulnerability. 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. Patchstack classifies this as low priority, noting it is unlikely to be exploited despite the class of vulnerability being used in mass-exploit campaigns targeting WordPress plugins (Patchstack).

The vendor has released version 1.0.4 of the Studio99 WP Monitor plugin, which patches this vulnerability. Site administrators should update the plugin to version 1.0.4 or later immediately. If an immediate update is not possible, site owners should consult their hosting provider or web developer for assistance. Patchstack users can enable auto-update for vulnerable plugins as an additional safeguard (Patchstack).
