The server trusts that `n` has an acceptable value, however when using a \nmaliciously large value, it allocates an array/slice of `n` of strings before filling the slice with data.\n\nThis behaviour was introduced ~7yrs ago [1].\n\n### Recommendation\n\nThe `/v2/_catalog` endpoint was designed specifically to do registry syncs with search or other API systems. Such an endpoint would create a lot of load on the backend system, due to overfetch required to serve a request in certain implementations.\n\nBecause of this, we strongly recommend keeping this API endpoint behind heightened privilege and avoiding leaving it exposed to the internet.\n\n###  For more information\n\nIf you have any questions or comments about this advisory:\n* Open an issue in [distribution repository](https://github.com/distribution/distribution)\n* Email us at [cncf-distribution-security@lists.cncf.io](mailto:cncf-distribution-security@lists.cncf.io)\n\n[1] [faulty commit](https://github.com/distribution/distribution/blob/b7e26bac741c76cb792f8e14c41a2163b5dae8df/registry/handlers/catalog.go#L45)","status":"published","published":"2023-05-11T20:37:54Z","modified":"2026-09-10T03:50:01.553051588Z","cvss":[{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high"}],"cwes":["CWE-475","CWE-770"],"updated_at":"2026-11-02T15:46:49.621585Z"},{"id":"UBUNTU-CVE-2023-2253","description":"A flaw was found in the `/v2/_catalog` endpoint in distribution/distribution, which accepts a parameter to control the maximum number of records returned (query string: `n`).
