CVE-2025-58006 is a medium-severity vulnerability classified as CWE-601, an 'Open Redirect' issue found in the CRM Perks WP Gravity Forms Keap/Infusionsoft plugin for WordPress. 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. Specifically, the affected product is the WP Gravity Forms Keap/Infusionsoft plugin versions up to 1.2.4. The vulnerability arises because the plugin fails to properly validate redirect URLs, enabling attackers to exploit this behavior for phishing attacks by luring users into clicking seemingly legitimate links that redirect to malicious domains. The CVSS 3.1 base score is 4.7 (medium), reflecting that the attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R). The scope is changed (S:C) because the vulnerability can affect resources beyond the vulnerable component, and the impact is limited to confidentiality (C:L) with no impact on integrity or availability. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability was reserved in August 2025 and published in September 2025, indicating recent discovery. This type of vulnerability is commonly leveraged in social engineering campaigns, where attackers exploit user trust in legitimate domains to redirect victims to phishing or malware distribution sites. Since the plugin integrates with Keap/Infusionsoft CRM systems, organizations using this plugin for customer data collection and marketing automation are at risk of reputational damage and potential data exposure through phishing-induced credential theft or malware infection.

For European organizations, the impact of this vulnerability primarily revolves around increased phishing risks and potential compromise of user credentials or sensitive information. Organizations using WordPress sites with the CRM Perks WP Gravity Forms Keap/Infusionsoft plugin may see attackers exploit open redirects to deceive customers, partners, or employees into visiting malicious sites. This can lead to credential theft, unauthorized access to corporate systems, or malware infections. The reputational damage from successful phishing campaigns can be significant, especially for companies handling sensitive customer data under GDPR regulations, potentially resulting in regulatory fines and loss of customer trust. Additionally, phishing campaigns leveraging this vulnerability could target employees to gain initial footholds in corporate networks, increasing the risk of broader cyberattacks. Given that the vulnerability does not directly affect system integrity or availability, the immediate technical damage is limited, but the indirect consequences through social engineering can be severe. The medium CVSS score reflects this indirect but impactful threat vector. Organizations in sectors with high customer interaction via web forms, such as e-commerce, financial services, and marketing, are particularly vulnerable.

To mitigate this vulnerability effectively, European organizations should: 1) Immediately audit their WordPress installations to identify the presence and version of the CRM Perks WP Gravity Forms Keap/Infusionsoft plugin. 2) If the plugin is present and unpatched, consider disabling or removing it until a vendor patch is available. 3) Implement strict URL validation and sanitization on all redirect parameters within web applications, ensuring redirects only point to trusted internal URLs or explicitly whitelisted domains. 4) Employ web application firewalls (WAFs) with rules to detect and block suspicious redirect patterns associated with this vulnerability. 5) Educate users and employees about phishing risks, emphasizing caution when clicking on links, even from trusted domains. 6) Monitor web traffic and logs for unusual redirect activity or spikes in phishing attempts. 7) Coordinate with CRM and plugin vendors to obtain timely patches and updates. 8) Consider deploying browser security policies such as Content Security Policy (CSP) to restrict navigation to untrusted domains. 9) Use multi-factor authentication (MFA) to reduce the impact of credential theft resulting from phishing. These measures go beyond generic advice by focusing on immediate plugin management, proactive detection, user awareness, and layered defenses tailored to the nature of open redirect vulnerabilities.
