Check whether my systems are affected by CVE-2026-129143 (paicoding 1.0.3 Missing Authorization via Article Detail API Endpoint), 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.

Affected:
- itwanger paicoding: versions 1.0.3
Fixed versions: none listed yet.
Conditions (all must be true for the bug to be hit):
- Paicoding version 1.0.3 is affected. (source: https://www.vulncheck.com/advisories/paicoding-1.0.3-missing-authorization-via-article-detail-api-endpoint)
- The article detail endpoint GET /article/api/data/detail/{articleId} is reachable and lacks an authorization check. (source: https://www.vulncheck.com/advisories/paicoding-1.0.3-missing-authorization-via-article-detail-api-endpoint)
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.

CISA KEV: CVE-2026-129143 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-129143 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-2026-129143 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-2026-129143

### What does this mean?

An unauthenticated attacker can read the full content of paid, login-only, member-only and draft articles. The article detail endpoint GET /article/api/data/detail/{articleId} lacks an authorization check, so attackers can enumerate article IDs to retrieve the content.

Source: https://www.vulncheck.com/advisories/paicoding-1.0.3-missing-authorization-via-article-detail-api-endpoint

### Which versions are affected by CVE-2026-129143?

paicoding: version 1.0.3.

Source: https://cve.now/CVE-2026-129143

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

Paicoding version 1.0.3 is affected. To check an installation, confirm the paicoding version in use and whether GET /article/api/data/detail/{articleId} responds to requests made without logging in.

Source: https://www.vulncheck.com/advisories/paicoding-1.0.3-missing-authorization-via-article-detail-api-endpoint

### How do I fix CVE-2026-129143?

The checked facts do not name a fixed version or vendor patch for this issue. Check the vendor's advisory or repository for an update that adds an authorization check to the article detail endpoint.

Source: https://www.vulncheck.com/advisories/paicoding-1.0.3-missing-authorization-via-article-detail-api-endpoint

### What if there's no patch?

The checked facts name no workaround. Until a fix is available, limiting or blocking unauthenticated access to GET /article/api/data/detail/{articleId} at a gateway or proxy would reduce exposure.
