CVE-2016-20102 (GCVE-0-2016-20102)
Vulnerability from cvelistv5 – Published: 2026-10-20 20:31 – Updated: 2026-10-21 15:52 X_Known Exploited VulnerabilityTitle
JavaMelody < 1.60.0 Reflected XSS via monitoring graph parameter
Summary
JavaMelody before 1.60.0 contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to inject script by supplying crafted values in the graph parameter of /monitoring?part=graph. Attackers can include a closing script tag in the graph value, which is only JavaScript-escaped in HtmlCounterReport, to execute script in victims' browsers. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-18.
