AnalysisAIv1 – Jul 29, 2026

SQL injection in @hypequery/clickhouse before version 2.0.2 allows unauthenticated remote attackers to inject arbitrary SQL commands through a trailing backslash in a query parameter. All users passing user-controlled input are affected, and the vulnerability can lead to full disclosure, modification, or destruction of the database. A vendor patch is available, and there is no evidence of active exploitation in the wild.

DescriptionCVE.org

Impact

A SQL injection vulnerability exists in the escapeValue() function used for parameter substitution. Attackers who can control parameter values can inject arbitrary SQL by using a trailing backslash to escape the closing quote.

Who is impacted: All users of @hypequery/clickhouse versions prior to 2.0.2 who pass user-controlled input as query parameters.

Patches

The vulnerability has been patched in version 2.0.2. The fix properly escapes backslashes before escaping single quotes

Workarounds

No workaround exists other than upgrading. Manual input validation/sanitization is not recommended as a mitigation - the library must handle escaping correctly.

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.
