CVE-2026-108114: Strapi improper authorization in API token permission reconciliation

CVE-2026-108114 · Severity: medium · CVSS 4.3 · Published 2026-10-10

Strapi is an open-source headless content management system used to manage and deliver content via APIs. A vulnerability in versions 5.47.0 through 5.57.0 allows admin API tokens to bypass field-level access controls that administrators have put in place. An attacker with a compromised token could read sensitive content fields that should have been restricted, potentially exposing confidential data.

Technologies: Strapi. Vendors: Strapi.

Technical details

The vulnerability exists in the API token permission reconciliation logic (reconcileTokenPermissionsToUserCeiling), which fails to enforce field-level restrictions when permissions have omitted or null fields. When an administrator restricts a role's access to specific content fields, existing tokens for that role retain access to all fields, allowing attackers to bypass the intended restrictions. The issue affects the Content Manager API token authorization path without requiring additional authentication beyond possessing a valid token.
