CVE-2026-65055 Details
Description
Taiga 6.10.1 contains a missing authorization vulnerability that allows unauthenticated attackers to disclose the full member roster and internal workflow configuration of any private project by supplying a project ID to the filters_data API endpoints on UserStory, Task, Issue, and Epic viewsets. Attackers can send unauthenticated GET requests to the filters_data endpoints with sequential integer project IDs to enumerate private project membership details including user IDs, full names, and gravatar hashes, bypassing the access controls that correctly restrict other project API endpoints.
A missing authorization vulnerability has been identified in Taiga version 6.10.1. This vulnerability allows unauthenticated attackers to access the full member roster and internal workflow configuration of any private project. The issue arises in the 'filters_data' API endpoints of the UserStory, Task, Issue, and Epic viewsets. By supplying a project ID to these endpoints, attackers can enumerate private project membership details, including user IDs, full names, and gravatar hashes. This exploitation bypasses the access controls that normally restrict other project API endpoints.
Users are advised to update to Taiga version 6.10.2, where this vulnerability has been addressed.
