Technical ContextAI · show details

This vulnerability is classified under CWE-367. A race condition vulnerability exists in the mintplex-labs/anything-llm repository, specifically within the user invite acceptance process. Attackers can exploit this vulnerability by sending multiple concurrent requests to accept a single user invite, allowing the creation of multiple user accounts from a single invite link intended for only one user. This bypasses the intended security mechanism that restricts invite acceptance to a single user, leading to unauthorized user creation without detection in the invite tab. The issue is due to the lack of validation for concurrent requests in the backend. Affected products include: Mintplexlabs Anythingllm.
