{"cve":"CVE-2026-45796","nvd":{"published":"2026-07-07T22:16:52.317","modified":"2026-07-08T19:47:08.010","status":"Analyzed","description":"Coder allows organizations to provision remote development environments via Terraform. Versions prior tp 2.24.5, 2.29.13, 2.30.8, 2.31.12, 2.32.2, and 2.33.3 are vulnerable to unauthenticated semi-blind Server-Side Request Forgery (SSRF) via the Azure instance identity endpoint (`POST /api/v2/workspaceagents/azure-instance-identity`). An external attacker can force the Coder server to issue HTTP GET requests to arbitrary internal or external hosts by submitting a crafted PKCS#7 signature. The server does not return the target's response body, but error messages in the API response reveal whether the target is reachable and what type of failure occurred. Versions 2.24.5, 2.29.13, 2.30.8, 2.31.12, 2.32.2, and 2.33.3 patch the issue. As a workaround, if the Azure identity-auth mechanism is not being used then restrict access to the corresponding endpoint (`/api/v2/workspaceagents/azure-instance-identity`) using ingress firewall and/or proxy ACLs.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","score":6.5},"cwes":["CWE-918"],"references":["https://github.com/coder/coder/commit/57b11d405f17492aa789d4b9ff33366f961a37f8","https://github.com/coder/coder/pull/25274","https://github.com/coder/coder/releases/tag/v2.24.5","https://github.com/coder/coder/releases/tag/v2.29.13","https://github.com/coder/coder/releases/tag/v2.30.8"],"products":["coder:coder"],"source":"nvd","synced_at":"2026-10-19T22:42:16.820116992+00:00"},"epss":{"cve":"CVE-2026-45796","score":0.0043,"percentile":0.3726,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-686c-7vgv-v3fx","url":"https://osv.dev/vulnerability/GHSA-686c-7vgv-v3fx","summary":"Coder: Unauthenticated SSRF via Azure Instance Identity Endpoint","modified":"2026-06-25T18:56:27.652664171Z","packages":[{"ecosystem":"Go","name":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","ranges":[">=2.33.0-rc.0 <2.33.3"],"fixed":["2.33.3"]},{"ecosystem":"Go","name":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","ranges":[">=2.32.0-rc.0 <2.32.2"],"fixed":["2.32.2"]},{"ecosystem":"Go","name":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","ranges":[">=2.31.0 <2.31.12"],"fixed":["2.31.12"]},{"ecosystem":"Go","name":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","ranges":[">=2.30.0 <2.30.8"],"fixed":["2.30.8"]},{"ecosystem":"Go","name":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","ranges":[">=2.29.0 <2.29.13"],"fixed":["2.29.13"]},{"ecosystem":"Go","name":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","ranges":["<2.24.5"],"fixed":["2.24.5"]},{"ecosystem":"Go","name":"github.com/coder/coder","purl":"pkg:golang/github.com/coder/coder","ranges":["<=0.27.3"],"fixed":[]}]},{"id":"GO-2026-5169","url":"https://osv.dev/vulnerability/GO-2026-5169","summary":"Coder: Unauthenticated SSRF via Azure Instance Identity Endpoint in github.com/coder/coder","modified":"2026-06-25T18:45:13.503968282Z","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":["<2.24.5",">=2.29.0 <2.29.13",">=2.30.0 <2.30.8",">=2.31.0 <2.31.12",">=2.32.0-rc.0 <2.32.2",">=2.33.0-rc.0 <2.33.3"],"fixed":["2.24.5","2.29.13","2.30.8","2.31.12","2.32.2","2.33.3"]}]}],"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).
