CVE-2026-54214

MEDIUMPre-NVD 5.35.3
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 73% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
