CVE-2026-129165 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 9.4 (critical) and affects Tactical RMM; no fixed version is listed yet.

## Summary

AmidaWare's Tactical RMM has an arbitrary file read flaw in its report template preview endpoint, reachable remotely over the network by a user who already has login access with report management permission. That user can read server files, including the Django SECRET_KEY, which is reused as the NATS password, and use it to publish run-script commands to every managed agent.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Who should check

Teams running AmidaWare Tactical RMM 0.17.0 through 1.6.1, especially those with users holding report management permission on the RMM server.

Source: https://vul.yulun.ac.cn/20261028/tacticalrmm/ ("Affected versions: 0.17.0 to 1.6.1")

## Affected

- AmidaWare Tactical RMM: from 0.17.0, through 1.6.1

## Description

Tactical RMM 0.17.0 through 1.6.1 contains an arbitrary file read in the /reporting/templates/preview/ endpoint because WeasyPrint resolves file:// links in user-supplied template_md and embeds the files in the returned PDF. Users with report management permission can read the Django SECRET_KEY, reused as the NATS password, and publish runscript commands to every managed agent.

## What to do

## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2026-129165 (Tactical RMM 0.17.0 through 1.6.1 Arbitrary File Read via Report Preview), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2026-129165 (entry last updated 2026-11-13):
Affected:
- AmidaWare Tactical RMM: from 0.17.0, through 1.6.1
Fixed versions: none listed yet.
Conditions (all must be true for the bug to be hit):
- Tactical RMM versions 0.17.0 through 1.6.1 (source: https://vul.yulun.ac.cn/20261028/tacticalrmm/)
- Attacker holds an account with report management permission (source: https://vul.yulun.ac.cn/20261028/tacticalrmm/)
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
Attacker needs: network access, high-privilege login, no user action.
CISA KEV: CVE-2026-129165 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-129165 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

## FAQ

### Is CVE-2026-129165 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

Source: https://cve.now/CVE-2026-129165

### What does this mean?

The report preview endpoint can read arbitrary files on the server. The advisory says this can expose the Django SECRET_KEY, and that the NATS bus password can then be used to send runscript commands to every managed agent.

Source: https://vul.yulun.ac.cn/20261028/tacticalrmm/

### Which versions are affected by CVE-2026-129165?

Tactical RMM: from 0.17.0 through 1.6.1.

Source: https://cve.now/CVE-2026-129165

### Am I affected, and how do I check?

Tactical RMM versions 0.17.0 through 1.6.1 are in the affected range. The advisory's stated condition is an account with report management permission. Compare your installed Tactical RMM version with that range.

Source: https://vul.yulun.ac.cn/20261028/tacticalrmm/

### How do I fix CVE-2026-129165?

The checked facts name no fixed version or vendor patch, so no upgrade target can be given. Check the vendor's advisory for an update.

Source: https://vul.yulun.ac.cn/20261028/tacticalrmm/

### What if there's no patch?

The checked facts give no workaround. Limiting report management permission to accounts that need it addresses the stated condition for this issue.
