A Regular Expression Denial of Service vulnerability in GitLab CE/EE affecting all versions from 1.0.2 prior to 14.10.5, 15.0 prior to 15.0.4, and 15.1 prior to 15.1.1 allows an attacker to make a GitLab instance inaccessible via specially crafted web server response headers
An issue has been discovered in GitLab CE/EE affecting all versions from 8.13 prior to 14.10.5, 15.0 prior to 15.0.4, and 15.1 prior to 15.1.1. Under certain conditions, using the REST API an unprivileged user was able to change labels description.
Incorrect authorization in GitLab EE affecting all versions from 10.7 prior to 14.10.5, 15.0 prior to 15.0.4, and 15.1 prior to 15.1.1, allowed an attacker already in possession of a valid Deploy Key or a Deploy Token to misuse it from any location to access Container Registries even when IP address restrictions were configured.
Improper access control in the runner jobs API in GitLab CE/EE affecting all versions prior to 14.10.5, 15.0 prior to 15.0.4, and 15.1 prior to 15.1.1 allows a previous maintainer of a project with a specific runner to access job and project meta data under certain conditions
An open redirect vulnerability in GitLab EE/CE affecting all versions from 11.1 prior to 14.10.5, 15.0 prior to 15.0.4, and 15.1 prior to 15.1.1, allows an attacker to redirect users to an arbitrary location if they trust the URL.
An account takeover issue has been discovered in GitLab EE affecting all versions starting from 11.10 before 14.9.5, all versions starting from 14.10 before 14.10.4, all versions starting from 15.0 before 15.0.1. When group SAML SSO is configured, the SCIM feature (available only on Premium+ subscriptions) may allow any owner of a Premium group to invite arbitrary users through their username and email, then change those users' email addresses via SCIM to an attacker controlled email address and thus - in the absence of 2FA - take over those accounts. It is also possible for the attacker to change the display name and username of the targeted account.
