CVE-2025-49868 is an Open Redirect vulnerability (CWE-601) identified in the FunnelKit Automation By Autonami plugin, affecting versions up to 3.6.0. This vulnerability allows an attacker to craft malicious URLs that redirect users to untrusted external sites without proper validation or sanitization of the redirect destination parameter. The vulnerability is exploitable remotely without requiring authentication (AV:N/PR:N), but it does require user interaction (UI:R), such as clicking a crafted link. The vulnerability has a medium CVSS score of 4.7, reflecting its moderate impact primarily on confidentiality. The scope is marked as changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component, potentially impacting users redirected to malicious sites. The vulnerability does not affect system integrity or availability directly but can facilitate phishing attacks by misleading users into visiting attacker-controlled domains, potentially leading to credential theft, malware installation, or further social engineering. No known exploits are currently reported in the wild, and no patches have been linked yet. FunnelKit Automation By Autonami is a WordPress plugin used for marketing automation, including email campaigns and customer journey automation, which often involves redirecting users to various URLs. The lack of validation in redirect URLs creates a risk vector for attackers to abuse legitimate URLs for phishing campaigns, undermining user trust and potentially compromising user credentials or sensitive data through subsequent attacks.

For European organizations, the primary impact of this vulnerability lies in increased phishing risks. Organizations using FunnelKit Automation By Autonami may inadvertently facilitate phishing attacks by distributing URLs that redirect users to malicious sites. This can lead to credential compromise, unauthorized access to corporate resources, and potential data breaches. The reputational damage from successful phishing campaigns can be significant, especially for companies in regulated sectors such as finance, healthcare, and e-commerce, where trust and data protection are paramount. Additionally, phishing attacks exploiting this vulnerability could be leveraged to bypass multi-factor authentication or deliver malware payloads, increasing the risk of broader network compromise. Since the vulnerability does not directly affect system integrity or availability, the immediate operational disruption may be limited, but the indirect consequences through social engineering and credential theft can be severe. The medium severity rating suggests that while the vulnerability is not critical, it should be addressed promptly to prevent exploitation, especially in environments with high user interaction and sensitive data handling.

1. Immediate mitigation involves updating the FunnelKit Automation By Autonami plugin to the latest version once a patch is released by the vendor. 2. Until a patch is available, organizations should audit all URLs generated or used by the plugin to ensure they do not contain unvalidated redirect parameters. 3. Implement web application firewall (WAF) rules to detect and block suspicious redirect patterns associated with this vulnerability. 4. Educate users and staff about the risks of phishing and encourage verification of URLs before clicking, especially those originating from automated marketing campaigns. 5. Employ URL rewriting or validation mechanisms within the web application or proxy layers to restrict redirects only to trusted domains. 6. Monitor logs for unusual redirect activities or spikes in user complaints related to phishing attempts. 7. Consider disabling or limiting the use of redirect features in the plugin if feasible until a secure version is deployed. 8. Integrate phishing-resistant authentication methods such as hardware tokens or biometric factors to reduce the impact of credential theft.
