## Summary

Zr.Admin.NET, a product from izhaorui, has a path traversal flaw in its /common/DownloadFile endpoint, in commits 0ee1ab8 through eb9228a. An attacker who can reach the server over the network and holds any ordinary login can use it to read arbitrary files, including application settings that expose the JWT signing key and allow forging administrator tokens.

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

## Who should check

Teams running izhaorui Zr.Admin.NET builds from commit 0ee1ab8 through eb9228a, where any logged-in account can reach the download endpoint.

## Affected

- izhaorui Zr.Admin.NET: version range not reported

## Description

Zr.Admin.NET commit 0ee1ab8 through commit eb9228a contains a path traversal vulnerability that allows any logged-in user to read arbitrary server files via the path parameter of /common/DownloadFile. Attackers can supply absolute paths or ../ sequences to read appsettings files and use the JwtSettings SecretKey to forge administrator tokens.

## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2026-129464 (Zr.Admin.NET commit 0ee1ab8 through eb9228a Path Traversal via DownloadFile), 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-2026-129464 (entry last updated 2026-11-15):
Affected:
- izhaorui Zr.Admin.NET: version range not reported
Fixed versions: none listed yet.
Conditions (all must be true for the bug to be hit):
- Zr.Admin.NET builds from commit 0ee1ab8 through commit eb9228a (source: https://www.vulncheck.com/advisories/zr-admin-net-commit-0ee1ab8-through-eb9228a-path-traversal-via-downloadfile)
- Attacker holds any login account (source: https://vul.yulun.ac.cn/20261114/zr-admin-net/)
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
Attacker needs: network access, low-privilege login, no user action.
CISA KEV: CVE-2026-129464 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-129464 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.

Verify against the linked advisories before concluding, and cite the date you read each one:

## FAQ

### Is CVE-2026-129464 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-2026-129464

### What does this mean?

A path traversal flaw in DownloadFile lets a logged-in account read arbitrary files on the server. Configuration files holding the JWT secret key can be read this way, which allows forging administrator tokens.
