Technical Analysis
PraisonAI versions >=0.1.4 and <0.1.5 contain an authorization flaw (CWE-285) where workspace members can delete any resource within the workspace, including those owned by others, due to missing ownership or role validation on six DELETE endpoints. This allows a malicious or compromised member to irreversibly remove projects, agents, issues, labels, issue dependencies, and issue-label attachments. The issue is resolved in version 0.1.5.
Potential Impact
An attacker with a workspace member account can permanently delete all critical workspace content, including projects and issues, leading to total data loss and disruption of workspace operations. The vulnerability does not impact confidentiality but severely impacts integrity and availability.
Mitigation Recommendations
Upgrade PraisonAI to version 0.1.5 or later, where the authorization checks have been properly implemented to restrict deletion actions based on ownership and roles. No other mitigations are indicated.
