|---|---|---|---|---|---|---|
| CVE-2021-22863 | An improper access control vulnerability was identified in the GitHub Enterprise Server GraphQL API that allowed authenticated users of the instance to modify the maintainer collaboration permission of a pull request without proper authorization. By exploiting this vulnerability, an attacker would be able to gain access to head branches of pull requests opened on repositories of which they are a maintainer. Forking is disabled by default for organization owned private repositories and would prev | [email protected] | 8.1 | 0.97% | 2021-03-02 | 2026-06-16 |
| CVE-2021-22862 | An improper access control vulnerability was identified in GitHub Enterprise Server that allowed an authenticated user with the ability to fork a repository to disclose Actions secrets for the parent repository of the fork. This vulnerability existed due to a flaw that allowed the base reference of a pull request to be updated to point to an arbitrary SHA or another pull request outside of the fork repository. By establishing this incorrect reference in a PR, the restrictions that limit the Acti | [email protected] | 6.5 | 0.81% | 2021-03-02 | 2026-06-16 |
| CVE-2021-22861 | An improper access control vulnerability was identified in GitHub Enterprise Server that allowed authenticated users of the instance to gain write access to unauthorized repositories via specifically crafted pull requests and REST API requests. An attacker would need to be able to fork the targeted repository, a setting that is disabled by default for organization owned private repositories. Branch protections such as required pull request reviews or status checks would prevent unauthorized comm | [email protected] | 6.5 | 0.92% | 2021-03-02 | 2026-06-16 |
| CVE-2020-10519 | A remote code execution vulnerability was identified in GitHub Enterprise Server that could be exploited when building a GitHub Pages site. User-controlled configuration of the underlying parsers used by GitHub Pages were not sufficiently restricted and made it possible to execute commands on the GitHub Enterprise Server instance. To exploit this vulnerability, an attacker would need permission to create and build a GitHub Pages site on the GitHub Enterprise Server instance. This vulnerability a | [email protected] | 8.8 | 2.99% | 2021-03-02 | 2026-06-16 |
| CVE-2020-10518 | A remote code execution vulnerability was identified in GitHub Enterprise Server that could be exploited when building a GitHub Pages site. User-controlled configuration of the underlying parsers used by GitHub Pages were not sufficiently restricted and made it possible to execute commands on the GitHub Enterprise Server instance. To exploit this vulnerability, an attacker would need permission to create and build a GitHub Pages site on the GitHub Enterprise Server instance.

| CVE-2020-10517 | An improper access control vulnerability was identified in GitHub Enterprise Server that allowed authenticated users of the instance to determine the names of unauthorized private repositories given their numerical IDs. This vulnerability did not allow unauthorized access to any repository content besides the name. This vulnerability affected all versions of GitHub Enterprise Server prior to 2.22 and was fixed in versions 2.21.6, 2.20.15, and 2.19.21. This vulnerability was reported via the GitH | [email protected] | 4.3 | 1.05% | 2020-08-27 | 2026-06-16 |
| CVE-2020-10516 | An improper access control vulnerability was identified in the GitHub Enterprise Server API that allowed an organization member to escalate permissions and gain access to unauthorized repositories within an organization. This vulnerability affected all versions of GitHub Enterprise Server prior to 2.21 and was fixed in 2.20.9, 2.19.15, and 2.18.20. This vulnerability was reported via the GitHub Bug Bounty program. | [email protected] | 9.8 | 1.59% | 2020-06-03 | 2026-06-16 |
| CVE-2017-18365 | The Management Console in GitHub Enterprise 2.8.x before 2.8.7 has a deserialization issue that allows unauthenticated remote attackers to execute arbitrary code. This occurs because the enterprise session secret is always the same, and can be found in the product's source code. By sending a crafted cookie signed with this secret, one can call Marshal.load with arbitrary data, which is a problem because the Marshal data format allows Ruby objects. | [email protected] | 9.8 | 21.24% | 2019-03-28 | 2026-06-16 |
| CVE-2014-0177 | The am function in lib/hub/commands.rb in hub before 1.12.1 allows local users to overwrite arbitrary files via a symlink attack on a temporary patch file. | [email protected] | 3.6 | 0.39% | 2014-05-27 | 2026-06-16 |
| CVE-2012-5814 | Weberknecht, as used in GitHub Gaug.es and other products, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate. | [email protected] | 5.8 | 0.57% | 2012-11-04 | 2026-06-16 |
| CVE-2012-2055 | GitHub Enterprise before 20120304 does not properly restrict the use of a hash to provide values for a model's attributes, which allows remote attackers to set the public_key[user_id] value via a modified URL for the public-key update form, related to a "mass assignment" vulnerability. | [email protected] | 7.5 | 1.84% | 2012-04-05 | 2026-06-16 |
