CVE-2026-32598 in oneuptime
Summary
by MITRE • 03/13/2026
OneUptime is a solution for monitoring and managing online services. Prior to 10.0.24, the password reset flow logs the complete password reset URL — containing the plaintext reset token — at INFO log level, which is enabled by default in production. Anyone with access to application logs (log aggregation, Docker logs, Kubernetes pod logs) can intercept reset tokens and perform account takeover on any user. This vulnerability is fixed in 10.0.24.

The vulnerability identified as CVE-2026-32598 affects OneUptime, a comprehensive monitoring and management solution for online services. This security flaw exists in versions prior to 10.0.24 and represents a critical exposure in the password reset functionality that could enable unauthorized account access. The issue stems from improper logging practices within the authentication flow where the complete password reset URL is recorded in the application logs at the INFO level. This logging configuration is enabled by default in production environments, creating an inherent security risk that persists without explicit configuration changes.
The technical implementation flaw involves the password reset mechanism logging full URLs containing reset tokens in plaintext format. These tokens serve as temporary authentication credentials that allow users to reset their passwords and regain access to their accounts. When the system logs these complete URLs, the reset tokens become exposed in log files that are typically accessible to system administrators, monitoring tools, and other authorized personnel. The vulnerability is particularly concerning because the INFO level logging is enabled by default in production systems, meaning that organizations do not need to actively configure logging to encounter this exposure. This default configuration creates a scenario where reset tokens are persistently stored in log aggregation systems, container logs, and kubernetes pod logs without requiring additional access privileges.
The operational impact of this vulnerability extends beyond simple information disclosure to represent a full account takeover capability. An attacker who gains access to the application logs can extract the plaintext reset tokens and use them to reset any user's password without knowledge of the original password. This creates a direct path to unauthorized access and potential data compromise across all affected user accounts. The vulnerability affects all users of the platform who have accounts that could be targeted through the password reset process, making it a widespread concern for organizations using this monitoring solution. The exposure persists until the affected version is upgraded to 10.0.24 or later, during which time any attacker with log access can exploit this weakness.
The security implications of this vulnerability align with CWE-532, which addresses information exposure through log files, and represents a specific instance of improper logging that exposes sensitive authentication tokens. From an attack perspective, this vulnerability maps to multiple ATT&CK techniques including credential access through log harvesting and account manipulation. Organizations using OneUptime should immediately implement the remediation by upgrading to version 10.0.24 or later, which addresses this logging issue by ensuring that reset tokens are not exposed in log files. Additional mitigations include reviewing log access controls, implementing proper log sanitization, and ensuring that authentication tokens are not logged in any form. The vulnerability demonstrates the critical importance of proper logging practices in authentication systems and highlights how seemingly minor configuration issues can create significant security risks in production environments.
