CVE-2026-108048 in Alo Suite
Summary
by MITRE • 11/03/2026
Vulnerability due to a lack of request limits in Alosuite’s password recovery functionality. The ‘/Account/resetPwd’ endpoint does not enforce adequate restrictions on the number or frequency of password reset requests sent for a single account. As a result, a remote attacker can repeatedly call the endpoint to generate an unlimited number of password reset emails addressed to a user, causing an email flood and enabling abuse of the password recovery mechanism. The absence of request limits or other controls against automation can harm legitimate users, consume application and email infrastructure resources, and facilitate automated attacks against the password recovery service.

The vulnerability identified in Alosuite stems from a critical failure to implement rate limiting on the password recovery functionality, specifically within the /Account/resetPwd endpoint. This architectural oversight allows for an unrestricted volume of requests directed at a single user account without any throttling mechanisms or CAPTCHA challenges to distinguish between legitimate human users and automated scripts. In secure application design, identity management endpoints such as those handling authentication resets are high-value targets because they interact directly with external communication channels like email servers. The absence of request limits means that the system does not enforce constraints on the number or frequency of password reset attempts within a defined time window for any given account identifier. This lack of control creates an environment where automated tools can exploit the endpoint to generate an unlimited stream of password recovery emails addressed to specific targets, fundamentally undermining the integrity and availability of the authentication service.
From an operational perspective, this flaw leads directly to resource exhaustion and denial-of-service conditions against both the application infrastructure and the underlying email delivery systems. By repeatedly calling the reset endpoint, a remote attacker can flood the target user with notifications while simultaneously consuming server processing power, database connections, and SMTP relay resources on behalf of the organization. This abuse not only degrades performance for legitimate users but also incurs significant financial costs associated with email service usage if third-party providers are billed per message sent. Furthermore, this vulnerability facilitates broader attack campaigns by allowing adversaries to harass specific individuals or overwhelm security operations teams who may need to investigate unusual spikes in authentication-related events. The ability to automate these requests without detection indicates a failure to implement basic bot mitigation strategies that are standard for sensitive identity management workflows.
This issue aligns with CWE-770: Allocation of Resources Without Limits or Throttling, which describes scenarios where insufficient resource limits allow attackers to exhaust system capacity. Additionally, it maps to the MITRE ATT&CK technique T1595.002: Active Scanning: Vulnerability Scanning, as the exploitation involves probing and abusing a specific service endpoint to achieve disruptive effects. The vulnerability also touches upon CWE-640: Weak Password Recovery Mechanism for Forgotten Passwords, specifically regarding the lack of controls that prevent automated abuse of recovery processes. To mitigate this risk, developers must implement strict rate limiting policies on all authentication-related endpoints, ensuring that requests from a single IP address or user account are throttled after a minimal number of attempts within a short timeframe. Integrating CAPTCHA challenges for password reset actions and monitoring email send volumes can further prevent automated abuse. Security teams should also configure alerts for anomalous spikes in password recovery requests to enable rapid detection and response to ongoing exploitation attempts, thereby restoring the intended security posture of the identity management system.
