Weakness	CWE CWE-153 OWASP Top 10:2025 A05:2025 - Injection ASVS 5.0 V1 - Encoding and Sanitization Record delimiter neutralization
Impact	Complete system compromise — the attacker gains the ability to install malware, steal data, create backdoors, or pivot to other systems on the network. With a CVSS score of 9.8 (CRITICAL), this represents a critical risk.
Exploit ScenarioDerived	An attacker sends a specially crafted request to the vulnerable service that triggers code execution with the privileges of the running process.

AnalysisAIv1 – Mar 15, 2026

DataEase is an open source business intelligence and data visualization tool. Prior to version 2.10.11, a threat actor may take advantage of a feature in Java in which the character "ı" becomes "I" when converted to uppercase, and the character "ſ" becomes "S" when converted to uppercase. A threat actor who uses a carefully crafted message that exploits this character conversion can cause remote code execution. The vulnerability has been fixed in v2.10.11. No known workarounds are available.

Executive ViewAI

Why It Matters

DataEase versions prior to 2.10.11 contain a critical remote code execution vulnerability exploitable through Unicode character conversion in Java, enabling unauthenticated attackers to achieve arbitrary code execution on systems running vulnerable BI/data visualization deployments. Organizations using DataEase for business intelligence must upgrade immediately, as the vulnerability requires no authentication and has a high probability of exploitation.

Business Impact: Severe

Compensating Controls

Vendor-released patch: DataEase version 2.10.11. No known workarounds available-patching is the only remediation. Implement network-level access controls to restrict DataEase connectivity to trusted sources while patch deployment is in progress.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.
