    CVE-2026-48208

    An improper neutralization of active SVG content in OTRS or ((OTRS)) Community Edition ticket article rendering allows attackers to inject specially crafted SVG payloads via email content, leading to browser-side resource exhaustion and denial of service when affected tickets are opened by an agent or customer. The issue can be exploited without JavaScript execution and is not mitigated by the configured Content Security Policy (CSP). This issue affects OTRS: * 7.0.X * 8.0.X * 2023.X * 2024.X * 2025.X * 2026.X before 2026.4.X Please note that ((OTRS)) Community Edition 6.x and before are vulnerable. Products based on the ((OTRS)) Community Edition also very likely to be affected
