{"apiVersion":"1.0","identifier":"CVE-2026-72831","description":"The Flex Objects plugin (through 1.4.6, tested with Grav 2.0.11) contains an incorrect authorization vulnerability in its Flex Objects API. FlexApiController::update() checks only the general Flex directory permission and does not apply the additional target/field/super-admin checks enforced by the dedicated Users and Groups API controllers. An authenticated account with api.access, admin.login, and users.update permissions (but without api.users.write or admin.super) can use the generic /api/v1/flex-objects/user-accounts endpoint to change a super administrator-s password, or the /api/v1/flex-objects/user-groups endpoint to grant its group admin.super, resulting in full site takeover. Fixed in Flex Objects 1.4.7.","publishedAt":"2026-08-14T12:16:46","lastModifiedAt":"2026-08-28T16:18:24","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72831","cvssScore":8.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00302,"riskScore":0.9,"affectedProduct":"Flex Objects plugin","affectedVersions":"<=1.4.6","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72831","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72831","en":"https://www.redsauce.net/en/cves/CVE-2026-72831","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72831","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72831","de":"https://www.redsauce.net/de/cves/CVE-2026-72831","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72831","el":"https://www.redsauce.net/el/cves/CVE-2026-72831"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72831"}}
