# CVE-2026-113605: Stirling-PDF 2.13.2 through 3.2.0 H2 SQL Denylist Bypass via import-database

- Severity: CVSS 8.6 (High), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Published: 2026-10-20 · Updated: 2026-10-20

## Affected

- Stirling-Tools Stirling-PDF: from 2.13.2, through 3.2.0

## Description

Stirling-PDF from 2.13.2 through 3.2.0 contains an incomplete denylist in DatabaseService.validateSqlContent() that allows administrators to bypass H2 import restrictions using CREATE OR REPLACE ALIAS. Authenticated administrators can upload a crafted SQL backup to the import-database endpoint, where RUNSCRIPT defines H2 Java function aliases and restores Java-method execution.
