1) Path traversal (CVE-ID: CVE-2024-0402)

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences. A remote user can write files to arbitrary locations on the GitLab server while creating a workspace.


2) Incorrect Regular Expression (CVE-ID: CVE-2023-6159)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient input validation when processing regular expressions in Cargo.toml blob viewer. A remote user can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.


3) Cross-site scripting (CVE-ID: CVE-2023-5933)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data in the user name. A remote user can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.


4) Information disclosure (CVE-ID: CVE-2023-5612)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to excessive data output by the application. A remote attacker can read the user email address via tags feed although the visibility in the user profile has been disabled.


5) Improper Authorization (CVE-ID: CVE-2024-0456)

The vulnerability allows a remote attacker to bypass authorization checks.

The vulnerability exists due to improper authorization. A remote attacker can assign arbitrary users to MRs that they created within the project.
