CVE-2024-8334Network attack vector

Access-log forgery via unsanitized request data

Published Aug 30, 2024 · Updated Aug 30, 2024

Log injection in master-nan Sweet-CMS 5f441e022b8876f07cde709c77b5be6d2f262e3f and earlier allows remote authenticated users to alter access logs. LogHandler records request query, body, and response values without neutralizing control characters before persisting and emitting them through Zap. Low-privileged network access to an authenticated endpoint is sufficient to forge entries and impair log integrity.
