{"id":"CVE-2026-108738","summary":"Traccar 5.7 through 6.16.0 Login CSRF via OpenID Connect Callback","details":"Traccar 5.7 through 6.16.0 contains a cross-site request forgery vulnerability that allows attackers to log victims into attacker-controlled accounts because the OpenID Connect callback never validates the OAuth state parameter. Attackers can induce a victim's browser to load /api/session/openid/callback with their own authorization code, causing data the victim enters, such as registered devices, to land in the attacker's account.","modified":"2026-10-13T02:46:18.536580975Z","published":"2026-10-11T12:19:43.602Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/108xxx/CVE-2026-108738.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-352"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/108xxx/CVE-2026-108738.json"},{"type":"ADVISORY","url":"https://hackmd.io/@haind/traccar-oidc-client-missing-state-login-csrf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-108738"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/traccar-5.7-through-6.16.0-login-csrf-via-openid-connect-callback"},{"type":"PACKAGE","url":"https://github.com/traccar/traccar"},{"type":"ARTICLE","url":"https://github.com/traccar/traccar/blob/cfab560c79ee9c9eaa41c79c6df351e820d6284b/src/main/java/org/traccar/api/resource/SessionResource.java#L175-L193"},{"type":"ARTICLE","url":"https://github.com/traccar/traccar/blob/cfab560c79ee9c9eaa41c79c6df351e820d6284b/src/main/java/org/traccar/database/OpenIdProvider.java#L110-L198"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/traccar/traccar","events":[{"introduced":"f982ed08a3d21e8eb6e9bbf4c25698ecbaad5b37"},{"fixed":"cfab560c79ee9c9eaa41c79c6df351e820d6284b"}],"database_specific":{"extracted_events":[{"introduced":"5.7"},{"last_affected":"6.16.0"},{"fixed":"6.16.0"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["v6.15.3","v6.15.2","v6.15.1","v6.15.0","v6.14.5","v6.14.4","v6.14.3","v6.14.2","v6.14.1","v6.14.0","v6.13.3","v6.13.2","v6.13.1","v6.13.0","v6.12.2","v6.12.1","v6.12.0","v6.11.1","v6.11.0","v6.10.0","v6.9.1","v6.9.0","v6.8.1","v6.8.0","v6.7.3","v6.7.2","v6.7.1","v6.7.0","v6.6","v6.5","v6.4","v6.3","v6.2","v6.1","v6.0","v5.12","v5.11","v5.10","v5.9","v5.8","v5.7"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-108738.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
