{"id":"CVE-2020-37094","details":"EspoCRM 5.7.0 prior to 5.9.0 contains an authentication token reuse vulnerability that allows authenticated attackers to bypass two-factor authentication by exploiting token-to-password-hash mapping in application/Espo/Core/Utils/Authentication/Espo.php. Attackers can obtain an authentication token for a controlled account and replay it against any victim account sharing the same password, since tokens are bound to password hashes rather than unique per-user values, bypassing the victim's 2FA protections.","modified":"2026-08-07T15:13:43.256953Z","published":"2026-02-03T22:16:25.673Z","references":[{"type":"WEB","url":"https://www.espocrm.com"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/espocrm-two-factor-auth-bypass-via-auth-token-reuse-between-accounts-with-identical-passwords"},{"type":"FIX","url":"https://github.com/espocrm/espocrm/commit/b299220dd0c7acdaa1ed8be8ffd79c7985093c7a"},{"type":"EVIDENCE","url":"https://www.exploit-db.com/exploits/48376"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/espocrm/espocrm","events":[{"introduced":"0"},{"last_affected":"38e2650cdeddfa8e6a40a7bb5a46c4a5ce66a2c4"},{"fixed":"b299220dd0c7acdaa1ed8be8ffd79c7985093c7a"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"5.8.5"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:espocrm:espocrm:*:*:*:*:*:*:*:*"}}],"versions":["5.8.5","5.8.4","5.8.3","5.8.2","5.8.1","5.8.0","5.7.5","5.7.4","5.7.3","5.7.2","5.7.1","5.7.0","5.6.1","5.6.0","5.5.1","5.5.0","5.4.3","5.4.2","5.4.1","5.4.0","5.3.2","5.3.1","5.3.0","5.2.5","5.2.4","5.2.3","5.2.2","5.2.1","5.2.0","5.1.2","5.1.1","5.1.0","5.0.1","5.0.0","4.8.0","4.7.0","4.6.0","4.5.0","4.4.0","4.3.0","4.3.0-beta.2","4.3.0-beta.1","4.2.4","4.2.3","4.2.2","4.2.1","4.2.0","4.1.4","4.1.3","4.1.2","4.1.1","4.1.0","4.0.3","4.0.2","4.0.1","4.0.0","4.0.0-beta.4","4.0.0-beta.3","4.0.0-beta.2","4.0.0-beta.1","3.9.1","3.9.0","3.8.0","3.7.1","3.7.0","3.6.1","3.6.0","3.5.0","3.4.2","3.4.1","3.4.0","3.3.0","3.2.0","3.1.0","3.0.0","2.9.0","2.8.1","2.8.0","2.6.0","2.5.2","2.5.1","2.5.0","2.4.0","2.3.0","2.0.1","1.2.0","1.1.2","1.1.1","1.1.0","1.0.1","1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-37094.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
