{"id":"GHSA-29xf-69gq-m9jx","summary":"Coder: User-admin role can reset owner account password","details":"### Summary\n\nThe `PUT /api/v2/users/{user}/password` endpoint authorized only `ActionUpdatePersonal` and did not prevent a `user-admin` from resetting an `owner` account's password. It also did not require the current password when an admin reset another user's password.\n\n\u003e **Note:** Exploitation requires the privileged `user-admin` role so practical risk is limited to deployments that grant `user-admin` to less trusted operators.\n\n### Impact\n\nA `user-admin` could reset any owner's password without knowing it, authenticate as that owner and gain full deployment control, including templates, workspaces, licensing, organization settings and the ability to self-assign the `owner` role. This was a privilege escalation from `user-admin` to `owner`.\n\n### Patches\n\nThe fix prevents non-owner users from resetting the password of an account that holds the `owner` role.\n\nThe fix was backported to all supported release lines:\n\n| Release line | Patched version |\n|---|---|\n| 2.34 | [v2.34.2](https://github.com/coder/coder/releases/tag/v2.34.2) |\n| 2.33 | [v2.33.8](https://github.com/coder/coder/releases/tag/v2.33.8) |\n| 2.32 | [v2.32.7](https://github.com/coder/coder/releases/tag/v2.32.7) |\n| 2.29 (ESR) | [v2.29.17](https://github.com/coder/coder/releases/tag/v2.29.17) |\n\n### Workarounds\n\nRestrict the `user-admin` role to trusted administrators until upgrading.\n\n### Resources\n- Fix: #25709\n\n### Credits\n\nCoder would like to thank Anthropic's Security Team (ANT-2026-22436) for independently disclosing this issue!","aliases":["CVE-2026-55077","GO-2026-5906"],"modified":"2026-07-07T16:11:46.342705766Z","published":"2026-07-06T20:53:04Z","database_specific":{"cwe_ids":["CWE-285"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-07-06T20:53:04Z","nvd_published_at":null},"references":[{"type":"WEB","url":"https://github.com/coder/coder/security/advisories/GHSA-29xf-69gq-m9jx"},{"type":"WEB","url":"https://github.com/coder/coder/pull/25709"},{"type":"PACKAGE","url":"https://github.com/coder/coder"}],"affected":[{"package":{"name":"github.com/coder/coder/v2","ecosystem":"Go","purl":"pkg:golang/github.com/coder/coder/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.34.0"},{"fixed":"2.34.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-29xf-69gq-m9jx/GHSA-29xf-69gq-m9jx.json"}},{"package":{"name":"github.com/coder/coder/v2","ecosystem":"Go","purl":"pkg:golang/github.com/coder/coder/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.33.0"},{"fixed":"2.33.8"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-29xf-69gq-m9jx/GHSA-29xf-69gq-m9jx.json"}},{"package":{"name":"github.com/coder/coder/v2","ecosystem":"Go","purl":"pkg:golang/github.com/coder/coder/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.30.0"},{"fixed":"2.32.7"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-29xf-69gq-m9jx/GHSA-29xf-69gq-m9jx.json"}},{"package":{"name":"github.com/coder/coder/v2","ecosystem":"Go","purl":"pkg:golang/github.com/coder/coder/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.29.17"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-29xf-69gq-m9jx/GHSA-29xf-69gq-m9jx.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"}]}
