Danswer Ai/Danswer

A vulnerability in danswer-ai/danswer version 0.9.0 allows for denial of service through memory exhaustion. The issue arises from the use of a vulnerable version of the starlette package (<=0.49) via fastapi, which was patched in fastapi version 0.115.3. The vulnerability can be exploited by sending multiple requests to the /auth/saml/callback endpoint, leading to uncontrolled memory consumption and eventual denial of service.

In danswer-ai/danswer v0.3.94, administrators can set the visibility of pages within a workspace, including the search page. When the search page is set to be invisible, regular users cannot view the search page or access its functionalities from the front-end interface. However, the back-end does not verify the visibility status of the search page. Consequently, attackers can directly call the API to access the functionalities provided by the search page, bypassing the visibility restriction set by the administrator.

In version 0.4.1 of danswer-ai/danswer, a vulnerability exists where a basic user can create credentials and link them to an existing connector. This issue arises because the system allows an unauthenticated attacker to sign up with a basic account and perform actions that should be restricted to admin users. This can lead to excessive resource consumption, potentially resulting in a Denial of Service (DoS) and other significant issues, impacting the system's stability and security.
