{"id":"CVE-2026-13207","summary":"Frangoteam FUXA SCADA/HMI Authentication Bypass by Spoofing","details":"FUXA versions 1.3.1 and prior contain an authentication bypass vulnerability via dot-segment path normalization in the REST API. The API router fails to normalize dot-segment sequences before applying authentication middleware, allowing unauthenticated requests to access protected endpoints by prefixing paths with dot-segments such as /api/./users, /api/./roles, and /api/project/../users. These requests bypass authentication checks and return sensitive user and role data without credentials.","modified":"2026-07-15T01:49:05.948278947Z","published":"2026-06-30T20:24:33.449Z","database_specific":{"cna_assigner":"icscert","cwe_ids":["CWE-290"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/13xxx/CVE-2026-13207.json"},"references":[{"type":"WEB","url":"https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-181-02.json"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/13xxx/CVE-2026-13207.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-13207"},{"type":"ADVISORY","url":"https://www.cisa.gov/news-events/ics-advisories/icsa-26-181-02"},{"type":"PACKAGE","url":"https://github.com/frangoteam/FUXA/releases"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/frangoteam/fuxa","events":[{"introduced":"0"},{"last_affected":"c48f6560d8bc2e678322d2c5b21887d038a69c48"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"1.3.1"}]}}],"versions":["v1.3.1","v1.3.0","v1.2.9","v1.2.8","v1.2.7","v1.2.6","v1.2.4","untagged-fb3c7751ca725cb671dd","v1.2.1","v1.2.0","v1.1.19","v.1.1.18","v1.1.17","v1.1.16","v1.1.15","v1.1.14","v1.1.13","v1.1.12","v1.1.11-3","v1.1.11-2","v1.1.11","v1.1.10","v1.1.9","v1.1.8","v1.1.7","v1.1.6","v1.1.5","v1.1.4","v1.1.3","v1.1.2","v1.1.01","v1.0.11","v1.0.10","v1.0.9","v1.0.8","v1.0.7","v1.0.6","v1.0.5","v1.0.4","v1.0.3","v1.0.2","v1.0.1_alfa","v1.0.1","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-13207.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
