Summary
Zr.Admin.NET, from izhaorui, has an insecure direct object reference flaw in its front article API that lets a logged-in user change the visibility and pin state of other users' articles. An attacker can reach it remotely over the network with low-privilege credentials, then make private articles public and read them without logging in.
Written by anthropic/claude-haiku-5.5 from the sources below. Verify against them.
Original description
Zr.Admin.NET commit e6ceaf4 through commit eb9228a contains an insecure direct object reference vulnerability in FrontArticleController that allows authenticated users to change other users' article visibility and pin state. Attackers can send PUT /front/article/changePublic with their own UserId in the body to make private articles public, then read them anonymously via GET /front/article/{id}.

Check your systems with an agent
Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.
Check whether my systems are affected by CVE-2026-129455 (Zr.Admin.NET commit e6ceaf4 through eb9228a IDOR via front/article API), 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-2026-129455 (entry last updated 2026-11-15):
Affected:
- izhaorui Zr.Admin.NET: version range not reported
Fixed versions: none listed yet.
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
CISA KEV: CVE-2026-129455 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-129455 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:

Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.
Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.
