What is CVE-2026-69262?
CVE-2026-69262 is a high-severity missing authorization vulnerability in Flowiseai Flowise, published on 4 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, `DELETE /api/v1/chatflows/:id` authorized requests with checkAnyPermission('chatflows:delete,agentflows:delete'), so possession of either permission was sufficient to reach the delete path. The delete logic then resolved the target record only by id and workspaceId and did not validate the target resource type, allowing a caller with only agentflows:delete to delete a CHATFLOW and a caller with only chatflows:delete to delete an AGENTFLOW in the same workspace. This issue is fixed in version 3.1.3.
Weakness: CWE-863
