Source description

As published by the source; long descriptions are shortened.

Summary The getRealIpAddr() function in objects/functions.php trusts user-controlled HTTP headers to determine the client's IP address. An attacker can spoof their IP address by sending forged headers, bypassing any IP-based access controls or audit logging. Vulnerable Code File: objects/functions.php Attack Scenario 1. Attacker sends request with forged header: or 2. getRealIpAddr() returns the forged IP 3. Any IP-based rate limiting, access control, or audit log that relies on this function is bypassed Proof of Concept The server now believes the request came from localhost. Impact - Bypass IP-based rate limiting - Bypass IP-based access controls - Forge audit log entries - Potential privilege escalation if localhost is trusted

# Patch Next advisory brief: CVE-2026-33690

Advisory: AVideo vulnerable to IP Address Spoofing via Untrusted HTTP Headers in getRealIpAddr()
IDs: CVE-2026-33690, GHSA-8p2x-5cpm-qrqw
Record: https://patchnext.com/advisories/cve-2026-33690 (revision 1, source checked 26 Oct 2026, 14:39 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist wwbn/avideo: affected <= 26.0

## Suggested inspection (read-only)
- Packagist wwbn/avideo: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on wwbn/avideo.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-8p2x-5cpm-qrqw (GitHub-reviewed advisory GHSA-8p2x-5cpm-qrqw lists affected ranges: Packagist wwbn/avideo >=0 <=26.0)
