In @payloadcms/plugin-multi-tenant versions before 3.90.0 and canary versions before 4.0.0-canary.34, the default tenant array field access allows an authenticated user to assign the user's own account to other tenants. Deployments that replace the default behavior with secured tenants arrayFieldAccess.create and tenants arrayFieldAccess.update functions are not affected by this behavior. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":7.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N","score":7.1},"cwes":["CWE-862"],"references":["https://github.com/payloadcms/payload/commit/19b58692d20d3947f31124bf7a88ac14a5ebf02e","https://github.com/payloadcms/payload/releases/tag/v3.90.0","https://github.com/payloadcms/payload/security/advisories/GHSA-p96c-xwx8-3cqj"],"products":["payloadcms:payload"],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-105860","score":0.00193,"percentile":0.08894,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-p96c-xwx8-3cqj","url":"https://osv.dev/vulnerability/GHSA-p96c-xwx8-3cqj","summary":"Payload has a tenant authorization bypass in Multi-Tenant Plugin","modified":"2026-10-07T20:45:05.342379505Z","packages":[{"ecosystem":"npm","name":"@payloadcms/plugin-multi-tenant","purl":"pkg:npm/%40payloadcms/plugin-multi-tenant","ranges":["<3.90.0"],"fixed":["3.90.0"]},{"ecosystem":"npm","name":"@payloadcms/plugin-multi-tenant","purl":"pkg:npm/%40payloadcms/plugin-multi-tenant","ranges":[">=4.0.0-canary.0 <4.0.0-canary.34"],"fixed":["4.0.0-canary.34"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
