Published Jul 25, 2025 · Updated Nov 19, 2025

Arbitrary file read in Sitecore XM, XP, XC, and Managed Cloud 8.0 through 10.4 allows remote attackers to read server files without authentication. Sitecore has not disclosed the affected endpoint, component, or file-path handling operation because disclosure would expose the attack scenario. Exposure is limited to Content Management and standalone roles, including PaaS, containerized, and affected Managed Cloud deployments.
