{"apiVersion":"1.0","identifier":"CVE-2026-65984","description":"FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. In 1.3.2 and earlier, POST /api/refresh in server/api/auth/index.js falls back from current user data to decoded.groups, including when the user is deleted or groups is zero, and POST /api/heartbeat in server/api/index.js re-signs inbound JWT claims without validating the current database record. An attacker who possesses a previously issued privileged refresh cookie or access token can continue minting privileged JWTs after account deletion, disablement, role removal, or demotion. Continued refresh-cookie rotation can extend the stale session and preserve unauthorized access to user management, project manipulation, runtime configuration, scripts, and backdoor-account creation. This issue is fixed in version 1.3.3.","publishedAt":"2026-08-18T20:17:20","lastModifiedAt":"2026-08-19T19:17:22","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-65984","cvssScore":7.5,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:L/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","epssProbability":0.00467,"riskScore":0.78,"affectedProduct":"FUXA","affectedVersions":"<=1.3.2","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-65984","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-65984","en":"https://www.redsauce.net/en/cves/CVE-2026-65984","fr":"https://www.redsauce.net/fr/cves/CVE-2026-65984","pt":"https://www.redsauce.net/pt/cves/CVE-2026-65984","de":"https://www.redsauce.net/de/cves/CVE-2026-65984","sk":"https://www.redsauce.net/sk/cves/CVE-2026-65984","el":"https://www.redsauce.net/el/cves/CVE-2026-65984"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-65984"}}
