CVE-2023-26429Network attack vector

Feedback export corruption via unsanitized control characters

Published Jun 20, 2023 · Updated Aug 2, 2024

Control-character injection in OX App Suite backend 7.10.6-rev39 and 8.10 allows remote authenticated users to corrupt feedback exports. The feedback export path copies user-supplied feedback into structured output without removing non-whitespace control characters. A valid user account and crafted feedback are required; injected bytes can break the exported data structure without reported data disclosure.
