CVE-2026-54214 PUBLISHED

TeamDavid: Header Injection through the 'cType' URL parameter

Assigner: NCSC.ch
Reserved: 12.06.2026 Published: 07.08.2026 Updated: 07.08.2026

Tobit Laboratories AG TeamDavid's Webbox application is vulnerable to HTTP header injection through the “cType” URL parameter, which allows arbitrary modification of the Content-Type header in HTTP responses. Because the parameter does not properly restrict control characters such as URL-encoded newlines (“%0a”) or colons, attackers can inject additional headers including extra Location headers into the server’s response. This results e.g. in an open redirect vulnerability. This issue affects TeamDavid through Rollout 524.
