Detailsinfo

A vulnerability was found in MervinPraison PraisonAI up to 0.1.3 and classified as critical. Affected by this issue is the function require_workspace_member of the component DependencyService. The manipulation of the argument depends_on_issue_id with an unknown input leads to a resource injection vulnerability. Using CWE to declare the problem leads to CWE-99. The product receives input from an upstream component, but it does not restrict or incorrectly restricts the input before it is used as an identifier for a resource that may be outside the intended sphere of control. Impacted is confidentiality, integrity, and availability. CVE summarizes:

PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have an Insecure Direct Object Reference. The dependency endpoints (`POST/GET /workspaces/{workspace_id}/issues/{issue_id}/dependencies` and `DELETE .../dependencies/{dep_id}`) gate access on `require_workspace_member(workspace_id)` only, then dispatch to `DependencyService` calls that take URL/body-supplied issue and dependency IDs without verifying any of them belong to the membership-checked workspace. Most damaging: `create_dependency` accepts `body.depends_on_issue_id` from the request body — that ID is checked against nothing — letting an attacker create a "blocks" or "related" link between any two issues anywhere in the database. PraisonAI Platform version 0.1.4 patches the issue.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-47406 since 05/19/2026. The exploitation is known to be easy. The attack may be launched remotely. There are known technical details, but no exploit is available.
