BIT-prometheus-2026-44903: Prometheus: Stored XSS via crafted histogram bucket label values in the heatmap display of the old Prometheus web UICVE-2026-44903 0 A stored cross-site scripting (XSS) vulnerability exists in the legacy Prometheus web UI's heatmap chart view. The issue arises because histogram bucket label values are not properly escaped when rendered as axis tick mark labels in HTML. An attacker able to inject crafted metrics can execute arbitrary JavaScript in the browsers of users viewing the affected heatmap UI. This vulnerability affects multiple Prometheus versions prior to 3.5.3 and 3.11.3 where the legacy UI is enabled. The issue is fixed in versions 3.5.3 and 3.11.3.
