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 79% 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 contains a reflected cross-site scripting (XSS) vulnerability. By sending a specially crafted link including an arbitrary path, an XSS payload or the parameter “EntryInfo”, and the parameter “!templateName=entryMail”, an attacker can cause the payload to execute in the victim’s browser when they click the link. This issue affects TeamDavid through Rollout 524.
