CVE-2026-22522 identifies a Missing Authorization vulnerability (CWE-862) in the Munir Kamal Block Slider WordPress plugin, versions up to 2.2.3. This vulnerability stems from incorrectly configured access control security levels, allowing attackers with low privileges (PR:L) to perform unauthorized actions remotely (AV:N) without requiring user interaction (UI:N). The vulnerability affects confidentiality (C:H) but does not impact integrity or availability. The plugin fails to properly verify whether a user has the necessary permissions before granting access to certain functionalities or data, potentially exposing sensitive information or enabling unauthorized data retrieval. Although no public exploits are known, the ease of exploitation combined with network accessibility makes this a notable risk for websites using this plugin. The vulnerability is particularly relevant for WordPress sites that rely on the Block Slider plugin for content display features, as attackers could leverage this flaw to access restricted content or configuration data. The CVSS 3.1 base score of 6.5 reflects a medium severity level, balancing the high confidentiality impact against the requirement for at least low-level privileges and the absence of integrity or availability impacts. The vulnerability was published on January 8, 2026, and no patches are currently linked, indicating that affected users should monitor for updates and consider interim mitigations.

For European organizations, this vulnerability poses a risk of unauthorized data disclosure within WordPress environments using the Munir Kamal Block Slider plugin. Confidential information managed or displayed via the plugin could be exposed to unauthorized users with low privileges, potentially leading to data leaks or privacy violations under regulations such as GDPR. While the vulnerability does not allow data modification or service disruption, the confidentiality breach alone can damage organizational reputation and lead to compliance issues. Organizations relying on this plugin for critical content presentation or internal data display are at higher risk. The remote exploitability without user interaction increases the attack surface, especially for publicly accessible websites. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once the vulnerability becomes widely known. European entities with large WordPress deployments or those in regulated industries should prioritize assessment and mitigation to prevent unauthorized access.

1. Monitor the Munir Kamal Block Slider plugin repository and vendor communications for official patches addressing CVE-2026-22522 and apply them promptly once available. 2. In the interim, restrict access to WordPress administrative and editor roles to trusted personnel only, minimizing the number of users with low-level privileges that could exploit this vulnerability. 3. Review and harden WordPress role and capability assignments to ensure users have the minimum necessary permissions, particularly focusing on access to the Block Slider plugin features. 4. Implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting the Block Slider plugin endpoints. 5. Conduct regular security audits and penetration tests focusing on access control weaknesses within WordPress plugins. 6. Enable detailed logging and monitoring of plugin-related activities to detect unauthorized access attempts early. 7. Consider temporarily disabling or removing the Block Slider plugin if it is not essential until a patch is released. 8. Educate site administrators about the risks of privilege escalation and the importance of strict access control.
