CVE-2026-54569Public exploitNetwork attack vector

Unauthenticated RCE via unchecked JSON API eval

Published Aug 26, 2026 · Updated Aug 26, 2026

Eval injection in SENAITE.CORE 2.0.0 through 2.6.0 allows remote attackers to execute arbitrary Python through the JSON API. Unchecked write routes resolve attacker-selected objects, and set_fields_from_request passes raw RecordField and RecordsField values to eval() before mutator permission checks. Anonymous access is sufficient on upstream-default deployments, exposing the Zope worker's laboratory data, files, and accounts to read, modification, or service interruption.
