An issue has been discovered in GitLab CE/EE affecting all versions from 7.7 before 17.8.7, 17.9 before 17.9.6, and 17.10 before 17.10.4. Under certain conditions, an attacker could potentially trick users into unintentionally authorizing sensitive actions on their behalf.
A Denial of Service (DoS) issue has been discovered in GitLab CE/EE affecting all up to 17.8.7, 17.9 prior to 17.9.6 and 17.10 prior to 17.10.4 A denial of service could occur upon injecting oversized payloads into CI pipeline exports.
An issue was discovered in GitLab CE/EE affecting all versions before 17.7.7, 17.8 prior to 17.8.5, and 17.9 prior to 17.9.2. where a denial of service vulnerability could allow an attacker to cause a system reboot under certain conditions.
An information disclosure vulnerability in GitLab CE/EE affecting all versions from 8.3 prior to 17.6.5, 17.7 prior to 17.7.4, and 17.8 prior to 17.8.2 allows an attacker to send a crafted request to a backend server to reveal sensitive information.
A Denial of Service (DoS) issue has been discovered in GitLab CE/EE affecting all versions starting from 7.14.1 prior to 17.3.7, 17.4 prior to 17.4.4, and 17.5 prior to 17.5.2. A denial of service could occur upon importing maliciously crafted content using the Fogbugz importer.
An issue was discovered in GitLab CE/EE affecting all versions prior to 16.11.6, starting from 17.0 prior to 17.0.4, and starting from 17.1 prior to 17.1.2, which allows a subdomain takeover in GitLab Pages.
An issue was discovered in GitLab CE/EE affecting all versions before 17.6.0 in which users were unaware that files uploaded to comments on confidential issues and epics of public projects could be accessed without authentication via a direct link to the uploaded file URL.
An issue has been discovered in GitLab EE/CE affecting all versions starting from 8.0 before 16.4. The product did not sufficiently warn about security implications of granting merge rights to protected branches.
The Ruby SAML library is for implementing the client side of a SAML authorization. Ruby-SAML in <= 12.2 and 1.13.0 <= 1.16.0 does not properly verify the signature of the SAML Response. An unauthenticated attacker with access to any signed saml document (by the IdP) can thus forge a SAML Response/Assertion with arbitrary contents. This would allow the attacker to log in as arbitrary user within the vulnerable system. This vulnerability is fixed in 1.17.0 and 1.12.3.
An issue was discovered in GitLab CE/EE affecting all versions starting from 8.2 prior to 17.1.6 starting from 17.2 prior to 17.2.4, and starting from 17.3 prior to 17.3.1, which allows an attacker to create a branch with the same name as a deleted tag.
