CVE-2024-32832 identifies a Missing Authorization vulnerability in the 'Login with phone number' product developed by Hamid Alinia, affecting all versions up to 1.6.93. Missing Authorization means that the system fails to properly verify whether a user has the necessary permissions to perform certain actions after authentication. In this case, the vulnerability occurs during the login process that uses phone numbers as identifiers. An attacker can exploit this flaw to bypass authorization controls, potentially gaining unauthorized access to user accounts or restricted application features. This could lead to unauthorized data access, privilege escalation, or account takeover. The vulnerability was reserved in April 2024 and published in August 2025, but no public exploits have been reported yet. The absence of a CVSS score indicates that the vulnerability is newly disclosed and not yet fully assessed. However, the nature of missing authorization in an authentication module is critical because it undermines the fundamental security principle of access control. The vulnerability affects all versions up to 1.6.93, indicating a broad impact on deployments using this product. The lack of patches or mitigation links suggests that users must rely on vendor updates or implement interim controls. The vulnerability is relevant to any organization using this login module, especially those relying on phone number authentication for user access.

The primary impact of CVE-2024-32832 is unauthorized access to systems or user accounts protected by the vulnerable 'Login with phone number' module. This can lead to confidentiality breaches where attackers access sensitive user data, integrity violations through unauthorized actions or changes, and availability issues if attackers disrupt services or lock out legitimate users. Organizations worldwide using this product or similar authentication mechanisms are at risk of account takeover, fraud, and potential lateral movement within their networks. The vulnerability could be exploited without user interaction or prior authentication, increasing the attack surface and ease of exploitation. This poses a significant threat to sectors relying on phone number-based authentication, such as financial services, telecommunications, and online platforms. The absence of known exploits currently limits immediate widespread impact, but the vulnerability's presence in authentication workflows makes it a high-value target for attackers. Failure to address this issue could result in reputational damage, regulatory penalties, and financial losses due to compromised user accounts and data breaches.

To mitigate CVE-2024-32832, organizations should first verify if they are using the affected versions (up to 1.6.93) of the 'Login with phone number' product by Hamid Alinia. If so, they should monitor vendor communications for patches or updates addressing this vulnerability and apply them promptly once available. In the interim, implement additional authorization checks at the application level to ensure that users cannot access restricted functionality without proper permissions. Employ multi-factor authentication (MFA) to reduce the risk of unauthorized access even if the login module is compromised. Conduct thorough logging and monitoring of login attempts, focusing on anomalies such as repeated failed attempts or logins from unusual locations or devices. Restrict access to sensitive functions behind additional access control layers independent of the vulnerable module. Review and harden session management to prevent session fixation or hijacking. Finally, perform security assessments and penetration testing focused on authentication and authorization flows to detect similar weaknesses.
