CVE-2025-62527: Taguette password reset link poisoning

Executive brief

Taguette is an open-source tool used for qualitative research and data analysis. A security flaw in the password reset process allows an attacker to send a deceptive email to a user that contains a malicious link. If the user clicks this link, the attacker can hijack the password reset process to gain unauthorized access to the user's account and research data.

Technical details

A password reset link poisoning vulnerability exists in Taguette versions prior to 1.5.0. The application fails to properly validate or restrict external control of system settings during the password reset request process (CWE-15). An unauthenticated remote attacker can trigger a password reset for a target user and manipulate the link generated in the resulting email. If the victim interacts with the poisoned link, the attacker can successfully reset the victim's password and gain full access to their account. This issue is resolved in version 1.5.0.
