CVE-2022-0895Public exploitNetwork attack vector

Authenticated HTML injection via unsanitized checkout fields

Published Mar 10, 2022 · Updated Aug 2, 2024

Static code injection in Microweber before 1.3 allows remote authenticated users to inject HTML through checkout contact fields. contactInformationSave() stores unsanitized first_name, last_name, email, and phone request values in the checkout_v2 session array. Low-privileged access and a crafted checkout submission are required; the public patch establishes attacker-controlled markup but not server-side PHP execution.
