| Title | REBUILD 4.4.7-release Improper Authentication |
|---|
| Description | During the security review of "REBUILD", I discovered an unauthenticated authentication bypass vulnerability in the "/user/login" endpoint. This vulnerability stems from the lack of strict token-purpose and endpoint validation, which causes a token exposed by a public share page to be accepted as a login credential. Therefore, attackers with access to a valid public share link can obtain the page token, submit it to the login endpoint, and establish a session identified as the fixed "SYSTEM_USER" administrator account. Immediate remedial measures are needed to ensure system security and protect data integrity. |
