CVE-2026-22411 is an authorization bypass vulnerability identified in Mikado-Themes Dolcino, a WordPress theme product, affecting versions up to and including 1.6. The vulnerability stems from incorrectly configured access control security levels that allow a user-controlled key to bypass authorization checks. This means that an attacker with low privileges (PR:L) can manipulate certain parameters or keys to gain unauthorized access to restricted functionalities or data without requiring user interaction (UI:N). The vulnerability is remotely exploitable over the network (AV:N) and impacts confidentiality and integrity (C:L/I:L) but does not affect availability (A:N). The CVSS 3.1 base score is 5.4, indicating a medium severity level. No known exploits are currently reported in the wild, and no patches have been released, which suggests that organizations must proactively assess and mitigate this risk. The issue is critical in environments where Dolcino themes are used to manage sensitive content or user data, as unauthorized access could lead to data leakage or unauthorized content modification. The vulnerability highlights the importance of correctly configuring access control mechanisms in web applications and themes to prevent privilege escalation and unauthorized operations.

For European organizations, this vulnerability poses a risk of unauthorized access to sensitive information or administrative functions within websites using the Dolcino theme. This could lead to data confidentiality breaches, unauthorized content changes, or exposure of user data. Since the vulnerability requires only low privileges and no user interaction, attackers could automate exploitation attempts remotely, increasing the threat surface. Organizations in sectors such as e-commerce, government, education, and media that rely on WordPress with Mikado-Themes may face reputational damage, regulatory non-compliance (e.g., GDPR violations), and operational disruptions if attackers leverage this flaw. The absence of an availability impact reduces the risk of service outages but does not diminish the severity of potential data integrity and confidentiality compromises. The medium severity rating suggests that while the vulnerability is not critical, it should be addressed promptly to prevent escalation and lateral movement within compromised environments.

1. Immediately review and audit access control configurations within the Dolcino theme settings and any customizations to ensure that user-controlled keys or parameters cannot override authorization checks. 2. Restrict privileges for users to the minimum necessary, especially limiting access to administrative or sensitive functions. 3. Monitor web server and application logs for unusual access patterns or attempts to manipulate keys or parameters related to authorization. 4. Implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting authorization mechanisms in the Dolcino theme. 5. Stay updated with Mikado-Themes vendor announcements for patches or security advisories and apply updates promptly once available. 6. Conduct penetration testing focused on authorization bypass scenarios to identify and remediate similar weaknesses. 7. Educate development and security teams about secure access control practices to prevent misconfigurations in future deployments.
