13 CVE

  1. CVE-2022-51026 9.8 Critique

    bytebase

    Bytebase 0.12.0 before 1.0.1 contains an authentication bypass vulnerability that allows unauthenticated attackers to log in as any user. The flaw stems from trusting client-supplied GitLab provider configuration in the POST /api/auth/login/GITLAB_SELF_HOST endpoint. Attackers can set instanceUrl to a server they control that returns an active user with a chosen email. Bytebase then issues session tokens for that principal, letting attackers impersonate existing users including the Owner or create new members.

  2. CVE-2026-16255 5.9 Moyenne

    GitLab

    GitLab has remediated an issue in GitLab EE affecting all versions from 12.0 before 19.3.6, 19.4 before 19.4.3, and 19.5 before 19.5.1 that, when the instance-wide SAML or LDAP membership lock was enabled, an authenticated user could have granted or accepted project and group membership outside the identity provider's control, due to incomplete enforcement of the membership lock on requests created before the lock was enabled.

  3. CVE-2026-15723 8.2 Élevée

    GitLab

    GitLab has remediated an issue in GitLab CE/EE affecting all versions from 10.1 before 19.3.6, 19.4 before 19.4.3, and 19.5 before 19.5.1 that, when OmniAuth SAML and LDAP auto-linking were both enabled, an authenticated user could have taken over an existing LDAP-backed account without any interaction from the targeted user, due to improper input sanitization in the LDAP email lookup path used during OmniAuth identity linking.

  4. CVE-2026-14288 3.1 Faible

    GitLab

    GitLab has remediated an issue in GitLab EE affecting all versions from 17.4 before 19.3.6, 19.4 before 19.4.3, and 19.5 before 19.5.1 that under certain conditions could have allowed an authenticated to bypass a required merge request approval policy on a protected branch due to improper access control during approval rule synchronization.

  5. CVE-2026-13319 4.3 Moyenne

    GitLab

    GitLab has remediated an issue in GitLab CE/EE affecting all versions from 15.10 before 19.3.6, 19.4 before 19.4.3, and 19.5 before 19.5.1 that, could have allowed an authenticated to read milestone metadata, including titles, descriptions, and full project paths, from arbitrary private projects across the instance without any project membership, due to missing authorization checks on a user-supplied project filter parameter in the group milestones API.

  6. CVE-2026-12664 6.8 Moyenne

    GitLab

    GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.2 before 19.3.6, 19.4 before 19.4.3, and 19.5 before 19.5.1 that, under certain conditions, could have allowed an authenticated user with a read_api-scoped token to retrieve a project's incoming email address and create work items, bypassing the token's restrictions, due to insufficient scope enforcement on a GraphQL field.

  7. CVE-2026-112378 4.3 Moyenne

    GitLab

    GitLab has remediated an issue in GitLab EE affecting all versions from 17.8 before 19.3.6, 19.4 before 19.4.3, and 19.5 before 19.5.1 that under certain conditions could have allowed an authenticated user to access paid AI features without a valid subscription due to insufficient server-side validation in billing eligibility checks.

  8. CVE-2026-112326 3.1 Faible

    GitLab

    GitLab has remediated an issue in GitLab EE affecting all versions from 17.8 before 19.3.6, 19.4 before 19.4.3, and 19.5 before 19.5.1 that, under certain conditions, could have allowed an authenticated user with read-only permissions to permanently delete existing vulnerability records due to improper cleanup logic that failed to distinguish between pre-existing records from newly created ones during error handling.

  9. CVE-2026-112212 7.5 Élevée

    GitLab

    GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.3 before 19.3.6, 19.4 before 19.4.3, and 19.5 before 19.5.1 that, under certain conditions, an unauthenticated user could have poisoned a shared cache's OAuth/OIDC discovery document to redirect certain flows to an externally controlled server, due to improper trust of user-supplied values when constructing endpoint URLs in cached discovery responses.

  10. CVE-2026-110264 10.0 Critique

    An issue has been discovered in GitLab CE/EE affecting all versions from 7.0 before 18.11.13, 19.0 before 19.0.10, 19.1 before 19.1.9, 19.2 before 19.2.9, 19.3 before 19.3.6, 19.4 before 19.4.3, and 19.5 before 19.5.1 that, under certain conditions, could have allowed an unauthenticated user to execute arbitrary code on the GitLab server due to integer overflow when compiling a specially crafted regular expression.

  11. CVE-2026-105777 4.3 Moyenne

    GitLab

    GitLab has remediated an issue in GitLab CE/EE affecting all versions from 17.6.5 before 19.3.6, 19.4 before 19.4.3, and 19.5 before 19.5.1 that, under certain conditions, an unauthenticated user could have retrieved sensitive internal server credentials due to improper filtering of internal response headers.

    GitLab

    GitLab has remediated an issue in GitLab CE/EE affecting all versions from 15.0 before 19.3.6, 19.4 before 19.4.3, and 19.5 before 19.5.1 that, when a merge request in a public project referenced a confidential issue from a private project, an authenticated user with no project membership could have read the confidential issue's title, due to a viewer-independent fragment cache key that incorrectly shared per-user-redacted rendered content across all users.

  13. CVE-2026-103515 2.7 Faible

    GitLab

    GitLab has remediated an issue in GitLab EE affecting all versions from 19.2 before 19.3.6, 19.4 before 19.4.3, and 19.5 before 19.5.1 that, when an instance administrator locked a group's Duo availability, an authenticated user with group Owner permissions could have re-enabled AI-backed data egress to a third-party service for that group and its descendant projects, due to insufficient granularity of the admin-lock enforcement controls.
