{"id":"CVE-2026-119533","kind":"vulnerability","aliases":["CVE-2026-119533"],"related":[],"title":"GitHub project boards exposed titles of private pull requests","description":"Repository and organization project boards listed the pull requests that reference each issue on the board without checking whether the viewer can read them. When a private pull request mentions an issue on a board the viewer can open, the board revealed the private repository's path and the pull request's number, title and state, to anonymous visitors in the case of a public board. The pull request body, diff and files were not exposed. Boards now skip linked pull requests in repositories where the viewer cannot read pull requests.","summary":"Public and shared GitHub project boards listed pull requests that reference board issues without checking the viewer's access.
