CVE-2025-14451 identifies an open redirect vulnerability (CWE-601) in the Solutions Ad Manager plugin for WordPress, specifically in all versions up to and including 1.0.0. The vulnerability stems from inadequate validation of the 'sam-redirect-to' URL parameter, which is used to redirect users after certain plugin actions. Because the parameter accepts arbitrary URLs without proper sanitization or whitelist enforcement, attackers can craft malicious URLs that redirect users to untrusted, potentially harmful websites. This attack vector does not require authentication, making it accessible to unauthenticated threat actors. However, exploitation requires user interaction, such as clicking a malicious link. The vulnerability impacts the integrity of user navigation by enabling phishing or social engineering attacks, though it does not directly compromise confidentiality or availability of the affected systems. The CVSS 3.1 base score is 4.7, reflecting a medium severity level due to network attack vector, low attack complexity, no privileges required, but requiring user interaction and limited impact on integrity only. No patches or known exploits are currently reported, but the vulnerability poses a risk to websites using this plugin, especially those involved in digital advertising where redirect functionality is common. The scope is limited to WordPress sites using the Solutions Ad Manager plugin, which may be niche but still relevant for targeted attacks.

For European organizations, the primary impact is the risk of users being redirected to malicious sites, which can facilitate phishing, malware delivery, or credential theft. This can erode user trust, damage brand reputation, and potentially lead to regulatory scrutiny under GDPR if user data is compromised downstream. The vulnerability does not directly affect system confidentiality or availability but can indirectly lead to broader security incidents if attackers leverage the redirect to deploy further attacks. Organizations relying on WordPress for marketing or advertising campaigns using this plugin are particularly vulnerable. The medium severity indicates moderate risk, but the ease of exploitation and unauthenticated access increase the likelihood of exploitation in phishing campaigns targeting European users. The impact is more pronounced in sectors with high user interaction and online advertising presence, such as e-commerce, media, and digital marketing agencies.

1. Monitor the Solutions by Steve vendor announcements for official patches and apply them promptly once released. 2. In the absence of patches, implement server-side validation or filtering to restrict the 'sam-redirect-to' parameter to a whitelist of trusted domains or internal URLs only. 3. Use Web Application Firewalls (WAFs) to detect and block suspicious redirect attempts involving this parameter. 4. Educate users and staff about the risks of clicking unsolicited or suspicious links, especially those involving redirects. 5. Conduct regular security audits of WordPress plugins and remove or replace those that are outdated or unsupported. 6. Employ Content Security Policy (CSP) headers to limit the domains to which users can be redirected or loaded from. 7. Monitor website logs for unusual redirect patterns that may indicate exploitation attempts. 8. Consider disabling or limiting the use of the redirect feature in the plugin configuration if possible until a patch is available.
