{"apiVersion":"1.0","identifier":"CVE-2026-80207","description":"APITable through 1.13.0-beta.1 annotates the create handler of InternalNotifyController with requiredLogin = false. ResourceInterceptor honours that annotation by returning before any session or API key is validated, and the nginx gateway shipped with the product proxies every /api request to the backend server, so POST /api/v1/internal/notification/create is reachable by any unauthenticated client that can reach the gateway. An attacker can persist arbitrary notifications in apitable_player_notification against any user ID they name, and because fromUserId can be set to 0 the message is stored with the system sender and renders in the victim-s inbox as a legitimate system notification. The body extras content is stored verbatim and forwarded to the frontend.","publishedAt":"2026-08-27T17:20:50","lastModifiedAt":"2026-08-27T20:18:48","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-80207","cvssScore":5.3,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","epssProbability":0.00286,"riskScore":0.54,"affectedProduct":"APITable","affectedVersions":"<=1.13.0-beta.1","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-80207","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-80207","en":"https://www.redsauce.net/en/cves/CVE-2026-80207","fr":"https://www.redsauce.net/fr/cves/CVE-2026-80207","pt":"https://www.redsauce.net/pt/cves/CVE-2026-80207","de":"https://www.redsauce.net/de/cves/CVE-2026-80207","sk":"https://www.redsauce.net/sk/cves/CVE-2026-80207","el":"https://www.redsauce.net/el/cves/CVE-2026-80207"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-80207"}}
