CVE-2026-82869: ToolJet Database before v3.16.44 Privilege Escalation via join_tables

Noroxi assessment

Priority: Monitor (action score 32/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.40% (FIRST EPSS).
  • Someone on the same network segment can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: ToolJet ToolJet 3.16.44.

Low priority for now. Upgrade to ToolJet ToolJet 3.16.44 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

ToolJet Database versions before v3.16.44 contain a privilege escalation vulnerability in the join_tables endpoint that grants JOIN_TABLES ability to all authenticated users without role or workspace membership validation. Attackers can read arbitrary ToolJet Database tables from any workspace by supplying victim workspace identifiers in the request path while authenticating with their own workspace credentials.
