An issue was discovered in GitLab Community and Enterprise Edition before 10.8.7, 11.0.x before 11.0.5, and 11.1.x before 11.1.2. XSS can occur via a Milestone name during a promotion.
GitLab Community and Enterprise Edition before 10.7.7, 10.8.x before 10.8.6, and 11.x before 11.0.4 allows Directory Traversal with write access and resultant remote code execution via the GitLab projects import component.
GitLab Community and Enterprise Editions before 10.1.6, 10.2.6, and 10.3.4 are vulnerable to an authorization bypass issue in the GitLab import component resulting in an attacker being able to perform operations under a group in which they were previously unauthorized.
GitLab Community and Enterprise Editions before 10.1.6, 10.2.6, and 10.3.4 are vulnerable to an unverified password change issue in the PasswordsController component resulting in potential account takeover if a victim's session is compromised.
An issue was discovered in GitLab Community Edition (CE) and Enterprise Edition (EE) before 10.5.8, 10.6.x before 10.6.5, and 10.7.x before 10.7.2. The Move Issue feature contained a persistent XSS vulnerability.
GitLab Community and Enterprise Editions version 8.4 up to 10.4 are vulnerable to XSS because a lack of input validation in the merge request component leads to cross site scripting (specifically, filenames in changes tabs of merge requests). This is fixed in 10.6.3, 10.5.7, and 10.4.7.
The Auth0 integration in GitLab before 10.3.9, 10.4.x before 10.4.6, and 10.5.x before 10.5.6 has an incorrect omniauth-auth0 configuration, leading to signing in unintended users.
GitLab Community and Enterprise Editions before 10.1.6, 10.2.6, and 10.3.4 are vulnerable to an authorization bypass issue in the Projects::MergeRequests::CreationsController component resulting in an attacker to see every project name and their respective namespace on a GitLab instance.
Gitlab Community and Enterprise Editions version 10.3.3 is vulnerable to an Insecure Temporary File in the project import component resulting remote code execution.
