Publication date: 2026-08-07

Last updated on: 2026-09-07

Assigner: Switzerland Government Common Vulnerability Program

Description

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 before Rollout 528. Starting with Rollout 528 (June 30, 2026), the affected functionality is disabled by default and the vulnerabilities are therefore no longer exposed through this functionality.

Compliance Impact

This vulnerability could lead to data breaches, which may violate GDPR's data protection requirements or HIPAA's safeguards for protected health information. Organizations using the affected software may face compliance violations, legal penalties, and reputational damage.

Mitigation Strategies
