CVE-2026-32306
Published: 13 March 2026
Summary
CVE-2026-32306 is a critical-severity SQL Injection (CWE-89) vulnerability in Hackerbay Oneuptime. Its CVSS base score is 9.9 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 32.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 RA-5 (Vulnerability Monitoring and Scanning) and SI-10 (Information Input Validation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly prevents SQL injection by requiring validation of user-controlled parameters like aggregationType before interpolating into ClickHouse SQL queries.
Ensures timely identification, reporting, and correction of flaws such as the lack of input validation and parameterization in the telemetry API.
Requires vulnerability scanning that would identify the SQL injection vulnerability in the ClickHouse query construction, enabling remediation before exploitation.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
SQL injection in public-facing API (T1190) enables arbitrary database read access (T1213.006) and modification; potential RCE via ClickHouse functions further facilitates execution.
NVD Description
OneUptime is a solution for monitoring and managing online services. Prior to 10.0.23, the telemetry aggregation API accepts user-controlled aggregationType, aggregateColumnName, and aggregationTimestampColumnName parameters and interpolates them directly into ClickHouse SQL queries via the .append() method (documented as "trusted SQL").…
more
There is no allowlist, no parameterized query binding, and no input validation. An authenticated user can inject arbitrary SQL into ClickHouse, enabling full database read (including telemetry data from all tenants), data modification, and potential remote code execution via ClickHouse table functions. This vulnerability is fixed in 10.0.23.
Deeper analysisAI
CVE-2026-32306 is a SQL injection vulnerability in OneUptime, an open-source solution for monitoring and managing online services. In versions prior to 10.0.23, the telemetry aggregation API accepts user-controlled parameters—aggregationType, aggregateColumnName, and aggregationTimestampColumnName—and interpolates them directly into ClickHouse SQL queries using the .append() method, which is documented as handling "trusted SQL." There is no allowlist, parameterized query binding, or input validation, allowing arbitrary SQL injection into the ClickHouse database.
An authenticated user with low privileges can exploit this vulnerability remotely with low complexity and no user interaction required. Successful exploitation enables full database read access, including sensitive telemetry data from all tenants, data modification, and potential remote code execution through ClickHouse table functions. The issue has a CVSS v3.1 base score of 9.9 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H) and is associated with CWE-89 (Improper Neutralization of Special Elements used in an SQL Command).
The vulnerability is fixed in OneUptime version 10.0.23. Additional details and mitigation guidance are available in the GitHub security advisory at https://github.com/OneUptime/oneuptime/security/advisories/GHSA-p5g2-jm85-8g35.
