Official Description

OneUptime is a solution for monitoring and managing online services. Prior to version 10.0.34, the fix for CVE-2026-32306 (ClickHouse SQL injection via aggregate query parameters) added column name validation to the _aggregateBy method but did not apply the same validation to three other query construction paths in StatementGenerator. The toSortStatement, toSelectStatement, and toGroupByStatement methods accept user-controlled object keys from API request bodies and interpolate them as ClickHouse Identifier parameters without verifying they correspond to actual model columns. ClickHouse Identifier parameters are substituted directly into queries without escaping, so an attacker who can reach any analytics list or aggregate endpoint can inject arbitrary SQL through crafted sort, select, or groupBy keys. This issue has been patched in version 10.0.34.

Technical Analysis

CVE-2026-33142 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), with a CVSS base score of 8.1.

From a weakness classification perspective (CWE-89): SQL injection vulnerabilities allow attackers to manipulate database queries, potentially exposing or modifying sensitive data.
