Stored XSS in Verba_CVE-2026-21730

5.3 / 10

MEDIUM

CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N

Description

Verba is affected by a Stored Cross-Site Scripting (XSS) vulnerability within its login logging mechanism. When an unauthenticated remote attacker attempts to log in using an incorrect username and password combination, the supplied username value is recorded in the application logs. Due to lack of input sanitization, an attacker can inject a malicious XSS payload into the username field.
This payload will be executed in the context of the administrator’s browser when the admin accesses the web application's log viewer.

The vendor was notified early about this vulnerability, but didn't respond to our messages. This issue was fixed in version 10.0.6
