CVE-2021-32712Network attack vector

Unauthenticated system disclosure via JSON error rendering

Published Jun 24, 2021 · Updated Aug 3, 2024

Information disclosure in Shopware before 5.6.10 allows remote attackers to obtain system details through crafted error requests. The frontend Error controller selects the JSON renderer solely from an application/json Content-Type header, causing exception data to be serialized in the response. No authentication or user interaction is required, and the disclosed details are limited to confidentiality-relevant system information.
