🚨Critical - xdocreport Velocity Template SSTI to RCE (CVE-2026-38165) xdocreport’s Velocity template engine configuration evaluates attacker-supplied template expressions; a crafted payload can escape the template context and reach Java execution primitives, leading to arbitrary code execution on the server. Deployments that only process trusted, static templates are not impacted. 👉Affected: xdocreport v0.9.2–v2.2.0
Post summary
The post discloses a critical SSTI vulnerability in xdocreport that can lead to arbitrary code execution, but it provides no evidence of exploits, patches, or active attacks.
