CVE-2026-54344 — ToolJet GitHub Actions comment body shell injection exposes deployment secrets

ToolJet is an open-source low-code platform for building internal tools. Prior to 3.20.180, ToolJet's render preview deployment workflow interpolates github.event.comment.body directly into a bash conditional in a run step, allowing any GitHub user who can comment on an open pull request with a deploy command to execute shell commands on the CI runner and exfiltrate deployment secrets. This issue is reported as fixed in version 3.20.180.

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
CISA SSVC: exploitation "poc"+5

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

First 24 hours

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).
Apply the documented mitigations until a definitive fix is available.
Search available logs for exploit probes matching the vulnerability class (injection), errors and authentication anomalies.
