The SSH key verification for a user can be bypassed by sending an SSH key offer without a signature. This allows bypassing authentication under following conditions: 1. The attacker knows the username and a valid target name 2. The attacked knows the user's public key and 3. Only SSH public key authentication is required for the user account. This issue has been addressed in version 0.8.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1},"cwes":["CWE-347","CWE-287"],"references":["https://github.com/warp-tech/warpgate/commit/a4df7f7a21395cfaee7a9789d1e3846290caeb63","https://github.com/warp-tech/warpgate/security/advisories/GHSA-3cjp-w4cp-m9c8","https://github.com/warp-tech/warpgate/commit/a4df7f7a21395cfaee7a9789d1e3846290caeb63","https://github.com/warp-tech/warpgate/security/advisories/GHSA-3cjp-w4cp-m9c8"],"products":["warpgate_project:warpgate"],"source":"nvd","synced_at":"2026-10-19T21:39:34.467980132+00:00"},"epss":{"cve":"CVE-2023-43660","score":0.00302,"percentile":0.22938,"date":"2026-10-31"},"kev":null,"osv":[],"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).
