Attackers can forge and tamper with session cookies to impersonate users, and on instances without access-auth codes configured, escalate to administrator privileges.","publishedAt":"2026-08-12T20:17:50","lastModifiedAt":"2026-08-26T16:56:50","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72793","cvssScore":8.6,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N","epssProbability":0.00241,"riskScore":0.88,"affectedProduct":"SiYuan","affectedVersions":"<3.7.4","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72793","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72793","en":"https://www.redsauce.net/en/cves/CVE-2026-72793","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72793","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72793","de":"https://www.redsauce.net/de/cves/CVE-2026-72793","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72793","el":"https://www.redsauce.net/el/cves/CVE-2026-72793"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72793"}}
