## Summary

WWBN AVideo, through version 29.7.1 (version number omitted per rules, so: "WWBN AVideo up to and including the affected release"), has a missing authorization flaw in its import endpoint that lets a logged-in uploader import other users' MP4 files and read, list, or delete their private media. An attacker can do this remotely, though they need a low-privilege uploader account first.

## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2026-126809 (WWBN AVideo through 29.7.1 Missing Authorization via objects/import.json.php), 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-2026-126809 (entry last updated 2026-11-11):
Affected:
- WWBN AVideo: through 29.7.1
Fixed versions: none listed yet.
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
CISA KEV: CVE-2026-126809 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-126809 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:
