CVE-2026-5730

Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to 1.9.1, an Insecure Direct Object Reference (IDOR) vulnerability in /api/v1/responses endpoint allows an authenticated attacker to execute any flow belonging to another user by specifying the victim's flow ID in the request. This vulnerability is fixed in 1.9.1.

Onlook through 0.2.32, fixed in commit 423e2e9, contains a broken object level authorization vulnerability that allows authenticated attackers to access and manipulate other users' resources by supplying arbitrary UUID values to tRPC API procedures including project.get, member.remove, and chat.conversation.delete. Attackers can provide arbitrary projectId or conversationId values without authorization validation to read, modify, and delete other users' project data, members, and conversation history.

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 issue CRUD endpoints (`GET / PATCH / DELETE /workspaces/{workspace_id}/issues/{issue_id}`) gate access on `require_workspace_member(workspace_id)` only, then resolve `issue_id` through `IssueService.get(issue_id)` which is a primary-key lookup with no workspace constraint. A user who is a member of any workspace `W1` can read, modify, or delete issues that belong to a different workspace `W2`. PraisonAI Platform version 0.1.4 patches the issue.

The agent CRUD endpoints (`GET / PATCH / DELETE /workspaces/{workspace_id}/agents/{agent_id}`) gate access on `require_workspace_member(workspace_id)` only, then resolve `agent_id` through `AgentService.get(agent_id)` which is a primary-key lookup with no workspace constraint. A user who is a member of any workspace `W1` can read, modify, or delete agents that belong to a different workspace `W2` by guessing or harvesting an agent UUID and calling `…/workspaces/W1/agents/<W2-agent-id>`. PraisonAI Platform version 0.1.4 patches the issue.

HCL DFXServer is affected by a Broken Authentication vulnerability via direct API access. The application fails to verify the user's authentication status when accessing specific API endpoints, allowing an unauthenticated attacker to interact with the APIs and perform unauthorized actions without valid credentials.

Nextcloud is an open source content collaboration platform. In Nextcloud Server from versions 32.0.0 to before 32.0.9, and 33.0.0 to before 33.0.3, with the knowledge of other users’ principal URL an attacker could possibly send a request to gain full access to their calendar. Therefore, the attacker must be an authenticated user. This is because of improper authorization controls in the backend of the calendar. If the attacker had access to the calendar, they would be able to view and modify it. It is recommended that the Nextcloud Server is upgraded to 33.0.3 or 32.0.9. It is recommended that the Nextcloud Enterprise Server is upgraded to 33.0.3, 32.0.9, 31.0.14.5, 30.0.17.9, 29.0.16.16, 28.0.14.17, 27.1.11.26, 26.0.13.26, 25.0.13.29, 24.0.12.34, 23.0.12.35, 22.2.10.39, or 21.0.9.23
