CVE-2024-12534 Information

Description

In version v0.3.32 of open-webui/open-webui the application allows users to submit large payloads in the email and password fields during the sign-in process due to the lack of character length validation on these inputs. This vulnerability can lead to a Denial of Service (DoS) condition when a user submits excessively large strings exhausting server resources such as CPU memory and disk space and rendering the service unavailable for legitimate users. This makes the server susceptible to resource exhaustion attacks without requiring authentication.
