Unauthenticated attackers can submit logins with the password \"hunter2\" and distinguish HTTP 403 from 401 responses to enumerate valid accounts and reveal the authentication provider of SSO-only users.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":6.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","score":3.7},"cwes":["CWE-203"],"references":["https://github.com/coder/coder/security/advisories/GHSA-8fxq-53rx-ph5f","https://www.vulncheck.com/advisories/coder-before-2.34.2-user-enumeration-via-login-placeholder-hash"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:08.599881581+00:00"},"epss":{"cve":"CVE-2026-111933","score":0.00225,"percentile":0.13094,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-8fxq-53rx-ph5f","url":"https://osv.dev/vulnerability/GHSA-8fxq-53rx-ph5f","summary":"Coder: Login endpoint user enumeration via timing-defense placeholder in password comparison","modified":"2026-10-18T10:55:40.994398805Z","packages":[{"ecosystem":"Go","name":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","ranges":[">=2.34.0 <2.34.2"],"fixed":["2.34.2"]},{"ecosystem":"Go","name":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","ranges":[">=2.33.0 <2.33.8"],"fixed":["2.33.8"]},{"ecosystem":"Go","name":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","ranges":[">=2.30.0 <2.32.7"],"fixed":["2.32.7"]},{"ecosystem":"Go","name":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","ranges":["<2.29.17"],"fixed":["2.29.17"]}]},{"id":"GO-2026-6265","url":"https://osv.dev/vulnerability/GO-2026-6265","summary":"Coder: Login endpoint user enumeration via timing-defense placeholder in password comparison in github.com/coder/coder","modified":"2026-10-18T10:55:40.994398805Z","packages":[{"ecosystem":"Go","name":"github.com/coder/coder","purl":"pkg:golang/github.com/coder/coder","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","ranges":["<2.29.17",">=2.30.0 <2.32.7",">=2.33.0 <2.33.8",">=2.34.0 <2.34.2"],"fixed":["2.29.17","2.32.7","2.33.8","2.34.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
