Private-project roster disclosure via unchecked filters_data lookups
Published Jul 21, 2026 · Updated Jul 21, 2026
Missing authorization in Taiga taiga-back 6.10.1 allows remote attackers to read private-project member and workflow data. The filters_data actions resolve an attacker-supplied project ID without a visibility check, while raw SQL helpers return membership and workflow rows filtered only by that ID. No account or project membership is required; sequential IDs expose user IDs, full names, gravatar hashes, roles, statuses, types, priorities, and severities from private projects.
