Vulnerability from github – Published: 2025-03-20 12:32 – Updated: 2025-03-21 17:26An improper access control vulnerability in open-webui/open-webui v0.3.8 allows attackers to view and delete any files. The application does not verify whether the attacker is an administrator, allowing the attacker to directly call the GET /api/v1/files/ interface to retrieve information on all files uploaded by users, which includes the ID values. The attacker can then use the GET /api/v1/files/{file_id} interface to obtain information on any file and the DELETE /api/v1/files/{file_id} interface to delete any file.

GHSA-PJ5G-V5V3-3C22
Vulnerability from github – Published: 2024-05-21 18:31 – Updated: 2025-01-31 12:33In lunary-ai/lunary version 1.2.2, an incorrect synchronization vulnerability allows unprivileged users to rename projects they do not have access to. Specifically, an unprivileged user can send a PATCH request to the project's endpoint with a new name for a project, despite not having the necessary permissions or being assigned to the project. This issue allows for unauthorized modification of project names, potentially leading to confusion or unauthorized access to project resources.

GHSA-PRC3-79C5-8H62
Vulnerability from github – Published: 2024-04-10 18:30 – Updated: 2024-04-15 18:30lunary-ai/lunary is vulnerable to a session reuse attack, allowing a removed user to change the organization name without proper authorization. The vulnerability stems from the lack of validation to check if a user is still part of an organization before allowing them to make changes. An attacker can exploit this by using an old authorization token to send a PATCH request, modifying the organization's name even after being removed from the organization. This issue is due to incorrect synchronization and affects the orgs.patch route.
