The vulnerability identified as CVE-2025-30822 is a Cross-Site Request Forgery (CSRF) flaw in the Hakik Zaman Custom Login Logo WordPress plugin, specifically affecting versions up to 1.1.7. CSRF vulnerabilities occur when a web application does not adequately verify that requests to change state or perform sensitive actions originate from legitimate users. In this case, the plugin fails to implement proper anti-CSRF protections, allowing an attacker to craft malicious web pages or links that, when visited by an authenticated WordPress administrator, cause unintended changes to the login logo or related plugin settings. The attacker exploits the trust the application places in the authenticated user's browser session. This vulnerability does not allow privilege escalation or direct code execution but can be leveraged to alter site appearance or potentially facilitate further social engineering attacks. No CVSS score has been assigned yet, and no public exploit is known. The plugin is used to customize the WordPress login page logo, a common feature for branding purposes. The lack of anti-CSRF tokens or nonce verification in the plugin's request handling is the root cause. The vulnerability was published on March 27, 2025, and is tracked by Patchstack. Since the plugin is a WordPress add-on, the attack surface is limited to sites that have installed and activated this specific plugin version. The vulnerability requires the victim to be logged in with administrative privileges, which limits the scope but still presents a risk to site integrity and user trust.

The primary impact of this CSRF vulnerability is unauthorized modification of the WordPress login page logo and potentially other plugin settings by an attacker without direct access to the administrator's credentials. This can lead to defacement, brand impersonation, or the insertion of malicious content that could mislead users or facilitate phishing attacks. While it does not directly compromise site confidentiality or availability, it undermines the integrity of the site’s appearance and could erode user trust. Organizations relying on this plugin for branding or security through obscurity may find their login pages altered, which could be leveraged in broader social engineering or targeted attacks. The requirement for an authenticated administrator session reduces the risk to some extent but does not eliminate it, especially in environments where administrators may visit untrusted sites. The vulnerability could also serve as a stepping stone for attackers to conduct further attacks if combined with other flaws or social engineering tactics. Overall, the impact is moderate but significant for organizations prioritizing site integrity and brand consistency.

To mitigate this vulnerability, organizations should: 1) Immediately update the Hakik Zaman Custom Login Logo plugin to a patched version once it becomes available from the vendor. 2) If a patch is not yet available, consider temporarily disabling or uninstalling the plugin to eliminate the attack surface. 3) Implement web application firewall (WAF) rules that detect and block suspicious POST requests targeting the plugin’s endpoints, especially those lacking valid anti-CSRF tokens. 4) Enforce strict administrative access controls, including limiting administrator logins to trusted networks or VPNs to reduce exposure to CSRF attacks. 5) Educate administrators to avoid visiting untrusted or suspicious websites while logged into the WordPress admin panel. 6) Monitor administrative actions and plugin configuration changes through logging and alerting to detect unauthorized modifications promptly. 7) Encourage the plugin developer to adopt standard WordPress nonce verification and anti-CSRF mechanisms in future releases. These steps collectively reduce the risk of exploitation and help maintain site integrity.
