CVE-2026-57121
PraisonAI: Missing ownership check on DELETE endpoints allows members to delete others' content in Platform API
Description
PraisonAI is a multi-agent teams system. From version 0.1.4 to before version 0.1.5 in praisonai-platform, a workspace member can permanently delete any resource — projects, agents, issues, labels, issue dependencies, and issue-label attachments — created by the workspace owner or other members. All six content DELETE endpoints enforce workspace membership but perform no ownership or role check. A single malicious or compromised member account can wipe an entire workspace's content irreversibly. This issue has been patched in version 0.1.5.
