CVE-2025-49292 is a medium-severity vulnerability classified under CWE-1284, which pertains to improper validation of specified quantity in input. This vulnerability affects the Cozmoslabs Profile Builder plugin, versions up to and including 3.13.8. The core issue lies in the plugin's failure to properly validate user-supplied input quantities, which can be manipulated by an attacker to facilitate phishing attacks. Specifically, the vulnerability allows an unauthenticated attacker to craft malicious input that, when processed by the Profile Builder, could lead to phishing scenarios targeting end users. The CVSS 3.1 base score is 4.3, indicating a medium impact primarily on integrity, with no direct impact on confidentiality or availability. The attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R), and the scope remains unchanged (S:U). No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability's exploitation could enable attackers to deceive users into divulging sensitive information or credentials by leveraging the improper input validation to inject or manipulate profile data or forms generated by the plugin.

For European organizations using the Cozmoslabs Profile Builder plugin, this vulnerability poses a risk of phishing attacks that could compromise user trust and lead to credential theft or social engineering exploits. Given that Profile Builder is commonly used in WordPress environments to manage user profiles and registration forms, exploitation could result in attackers crafting deceptive forms or profile data that appear legitimate to end users. This could undermine the integrity of user data and potentially facilitate further attacks such as account takeover or lateral movement within organizational networks. While the direct confidentiality and availability impacts are low, the indirect consequences of successful phishing—such as data breaches or fraud—could be significant. Organizations in sectors with high regulatory scrutiny, such as finance, healthcare, and public services, may face compliance and reputational risks if phishing attacks succeed due to this vulnerability.

European organizations should prioritize the following mitigation steps: 1) Monitor Cozmoslabs official channels for security patches and apply updates to Profile Builder promptly once available. 2) Implement strict input validation and sanitization at the web application firewall (WAF) or reverse proxy level to detect and block suspicious payloads targeting profile input fields. 3) Employ multi-factor authentication (MFA) to reduce the impact of credential theft resulting from phishing. 4) Conduct user awareness training focused on recognizing phishing attempts, especially those that may arise from manipulated profile or registration forms. 5) Regularly audit and review user-generated content and profile data for anomalies that could indicate exploitation attempts. 6) Limit exposure by restricting access to profile management interfaces and employing rate limiting to reduce automated exploitation attempts. 7) Consider deploying Content Security Policy (CSP) headers to mitigate the risk of malicious script execution stemming from injected content.
