The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to a race condition. A remote user can exploit the race leading to verified email forgery and takeover of third-party accounts when using GitLab as an OAuth provider.
2) Resource exhaustion (CVE-ID: CVE-2022-3613)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources. A remote attacker can use a specially crafted Prometheus Server query, trigger resource exhaustion and perform a denial of service (DoS) attack.
3) Information disclosure (CVE-ID: CVE-2022-4365)
The vulnerability allows a remote user to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application. A remote administrator can leak the sentry token by changing the configured URL in the Sentry error tracking settings page.
4) Information disclosure (CVE-ID: CVE-2022-4342)
The vulnerability allows a remote user to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application. A remote administrator can leak masked webhook secrets by changing target URL of the webhook.
5) Cross-site scripting (CVE-ID: CVE-2022-3573)
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 wiki changes page. 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.
6) Improper Authorization (CVE-ID: CVE-2022-4167)
The vulnerability allows a remote attacker to bypass authentication process.

7) Information disclosure (CVE-ID: CVE-2022-3870)
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 download user avatars using the victim's user ID, on private instances that restrict public level visibility.
8) Information disclosure (CVE-ID: CVE-2023-0042)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to arbitrary protocol redirection in GitLab Pages. A remote user can cause redirection to arbitrary protocols.
9) Input validation error (CVE-ID: CVE-2022-4131)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to device-detector parsing user agents. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
10) Input validation error (CVE-ID: CVE-2022-3514)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in the Submodule Url Parser. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
