CVE-2026-108114
MEDIUM 5.3Strapi 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.
No known exploitation, public exploit, or elevated probability at this time. Track for changes.
