Auth bypass in Strapi
CVE-2026-108114
Strapi 5.47.0 through 5.57.0 contains an improper authorization vulnerability that allows admin API tokens to retain all-field Content Manager access after the owner's role is field-restricted. Because reconcileTokenPermissionsToUserCeiling ignores token permissions with omitted or null fields, token holders can keep reading content fields an administrator removed from the role.
