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

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.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

EPSS FIRST

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (ToolJet ToolJet).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
