Description Summary:
Typemill's login endpoint lacks rate-limiting or account lockout mechanisms when the captcha is disabled, allowing for potential brute-force attacks.
Executive Summary:
A lack of authentication rate-limiting in Typemill versions up to 2.25.0 creates a high risk of unauthorized account access through brute-force attacks.
Vulnerability Details
CVE-ID: CVE-2026-71213
Affected Software: Typemill Typemill
Affected Versions: 0 through 2.25.0
Vulnerability: This is an improper restriction of excessive authentication attempts (CWE-307) occurring within the ControllerWebAuth login function. The vulnerability is exploitable by unauthenticated remote attackers.
Business Impact
The absence of account lockout or rate-limiting measures significantly increases the risk of successful credential stuffing or brute-force attacks against administrative or user accounts. With a CVSS score of 8.1, this vulnerability is considered High severity, as it could lead to full unauthorized access to the application and sensitive data compromise.
Remediation Plan
Immediate Action: Ensure the CAPTCHA feature is enabled in the Typemill configuration to mitigate automated login attempts while awaiting a formal security patch.
Proactive Monitoring: Review web access logs for high volumes of POST requests to the /tm/login endpoint originating from single or suspicious IP addresses.
Compensating Controls: Implement a Web Application Firewall (WAF) rule to rate-limit requests to the login endpoint and block IP addresses exhibiting aggressive authentication patterns.
Exploitation Status
Public Exploit Available: No
Analyst Notes: As of August 5, 2026, there is no public information indicating active exploitation or a public proof-of-concept for this vulnerability. The flaw is inherently exploitable due to the default configuration lacking protective barriers against automated login attempts.
Analyst Recommendation
Given the High severity score, administrators must prioritize securing the authentication process immediately. Enabling the CAPTCHA is a vital, non-disruptive step to prevent account takeover attempts until an official update providing robust rate-limiting is released.
