CVE-2026-22522 identifies a Missing Authorization vulnerability (CWE-862) in the Munir Kamal Block Slider plugin, a WordPress plugin used for creating sliders on websites. This vulnerability stems from improperly configured access control mechanisms that fail to adequately restrict actions to authorized users. Specifically, users with low-level privileges (PR:L) can exploit the vulnerability remotely (AV:N) without requiring any user interaction (UI:N). The vulnerability does not affect the integrity or availability of the system but can lead to a high impact on confidentiality (C:H), potentially exposing sensitive data or configuration details managed by the plugin. The affected versions include all versions up to 2.2.3, with no patch currently available as per the provided data. The vulnerability was reserved on January 7, 2026, and published on January 8, 2026, with no known exploits reported in the wild. The CVSS v3.1 vector indicates that the attack complexity is low (AC:L), meaning exploitation is straightforward once the vulnerability is understood. The plugin’s role in managing content display on WordPress sites means that unauthorized access could reveal sensitive business or user data embedded within slider content or administrative settings. Since the vulnerability requires only low privileges, it could be exploited by authenticated users with minimal access, such as subscribers or contributors, escalating their access to unauthorized data. The lack of user interaction requirement increases the risk of automated exploitation attempts. Overall, this vulnerability represents a significant risk to confidentiality in affected WordPress environments until remediated.

For European organizations, the primary impact of CVE-2026-22522 is the unauthorized disclosure of sensitive information managed through the Block Slider plugin. This could include proprietary marketing content, user data, or configuration details that could be leveraged for further attacks or competitive intelligence. While the vulnerability does not allow modification or destruction of data, the confidentiality breach could lead to reputational damage, regulatory non-compliance (especially under GDPR), and potential financial losses. Organizations relying on WordPress for e-commerce, media, or corporate websites are particularly at risk, as attackers could gain insights into internal processes or customer information. The ease of exploitation with low privileges and no user interaction means that insider threats or compromised low-level accounts could quickly escalate their access. Additionally, automated scanning tools could identify vulnerable sites across Europe, increasing the attack surface. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the potential for future exploitation. European entities must consider the regulatory implications of data exposure and the operational risks of unauthorized access to web assets.

1. Monitor for official patches or updates from the Munir Kamal Block Slider plugin developer and apply them immediately upon release. 2. In the absence of patches, implement strict access control policies at the WordPress level, restricting plugin management capabilities to trusted administrators only. 3. Audit user roles and permissions to ensure that low-privilege users do not have unnecessary access to plugin features or administrative endpoints. 4. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the Block Slider plugin endpoints. 5. Conduct regular security assessments and penetration tests focusing on WordPress plugins and their access controls. 6. Disable or remove the Block Slider plugin if it is not essential to reduce the attack surface. 7. Monitor logs for unusual access patterns or privilege escalations related to the plugin. 8. Educate site administrators on the risks of misconfigured access controls and the importance of timely updates. 9. Consider implementing multi-factor authentication (MFA) for all WordPress administrative accounts to reduce the risk of compromised credentials being exploited.
