Exploitation requires the highly privileged `Owner` role.\n\n### Patches\n\nThe fix escapes the `ApplicationName` and `LogoURL` appearance values in HTML output before rendering.\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 `Owner` role to trusted administrators.\n\n### References\n\n- Fix: #25804\n\n### Credits\n\nWe'd like to thank Anthropic's Security Team (ANT-2026-22453) for independently disclosing this issue!","state":0,"publishedAt":"2026-08-20T18:34:26+00:00","modifiedAt":"2026-10-18T10:55:43.8155513+00:00","affected":[{"ecosystem":"Go","name":"github.com/coder/coder/v2","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.34.0"},{"kind":"fixed","version":"2.34.2"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"Go","name":"github.com/coder/coder/v2","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.33.0"},{"kind":"fixed","version":"2.33.8"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"Go","name":"github.com/coder/coder/v2","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.30.0"},{"kind":"fixed","version":"2.32.7"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"Go","name":"github.com/coder/coder/v2","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"2.29.17"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:N/I:L/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"LOW"}],"references":["https://github.com/coder/coder/security/advisories/GHSA-h58c-xccx-75m3","https://github.com/coder/coder/pull/25804","https://github.com/coder/coder/commit/ec19bc41d80568c0eb9f74b526e8cc8ffbe3be9a","https://github.com/coder/coder","https://github.com/coder/coder/releases/tag/v2.29.17","https://github.com/coder/coder/releases/tag/v2.32.7","https://github.com/coder/coder/releases/tag/v2.33.8","https://github.com/coder/coder/releases/tag/v2.34.2"],"sourceUrl":"https://github.com/advisories/GHSA-h58c-xccx-75m3","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-h58c-xccx-75m3","identifiers":["GHSA-h58c-xccx-75m3","CVE-2026-111932","GO-2026-6267"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
