{"cve":"CVE-2026-64679","nvd":{"published":"2026-08-21T21:17:01.920","modified":"2026-10-12T16:10:00.220","status":"Deferred","description":"Atlantis is a self-hosted golang application that listens for Terraform pull request events via webhooks. From 0.19.8 until 0.45.0, Atlantis does not consistently validate user-controlled workspace values supplied through accepted repository-level atlantis.yaml configuration or authenticated /api/plan input before joining them into local workspace paths. Traversal segments can escape the intended per-pull workspace directory and cause clone preparation or other working-directory code paths to call os.RemoveAll, os.MkdirAll, or related filesystem operations on out-of-bounds directories before Terraform rejects the invalid workspace name. This can create, delete, or reuse writable paths with the privileges of the Atlantis process, causing integrity loss or denial of service. This issue is fixed in version 0.45.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","score":8.1},"cwes":["CWE-22","CWE-73"],"references":["https://github.com/runatlantis/atlantis/commit/ea4e4ceebf8b387d015fff7ed8a7fcca33279afe","https://github.com/runatlantis/atlantis/pull/6254","https://github.com/runatlantis/atlantis/releases/tag/v0.45.0","https://github.com/runatlantis/atlantis/security/advisories/GHSA-26w5-6g95-gj28","https://github.com/runatlantis/atlantis/security/advisories/GHSA-26w5-6g95-gj28"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-64679","score":0.00797,"percentile":0.56221,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-26w5-6g95-gj28","url":"https://osv.dev/vulnerability/GHSA-26w5-6g95-gj28","summary":"Atlantis Workspace Handling has Path Traversal that Allows Out-of-Bounds Directory Deletion/Creation","modified":"2026-08-26T01:12:51.034417848Z","packages":[{"ecosystem":"Go","name":"github.com/runatlantis/atlantis","purl":"pkg:golang/github.com/runatlantis/atlantis","ranges":[">=0.19.8 <0.45.0"],"fixed":["0.45.0"]}]},{"id":"GO-2026-6273","url":"https://osv.dev/vulnerability/GO-2026-6273","summary":"Atlantis Workspace Handling has Path Traversal that Allows Out-of-Bounds Directory Deletion/Creation in github.com/runatlantis/atlantis","modified":"2026-08-25T23:51:38.056368146Z","packages":[{"ecosystem":"Go","name":"github.com/runatlantis/atlantis","purl":"pkg:golang/github.com/runatlantis/atlantis","ranges":[">=0.19.8 <0.45.0"],"fixed":["0.45.0"]}]}],"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).
