CVE-2024-34899GHSA-f98p-2hc5-fm7v

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (wwbn/avideo 14.3), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

The PHP file view/about.php is vulnerable to an XSS issue due to no sanitization of the user agent. At line [53], the website gets the user-agent from the headers through $SERVER['HTTPUSERAGENT'] and echo it without any sanitization. In PHP, echo a user generated statement, here the User-Agent Header, without any sanitization allows an attacker to inject malicious scripts into the output of a web page, which are then executed in the browser of anyone viewing that page.

# Patch Next advisory brief: CVE-2024-34899

Advisory: AVideo cross-site scripting vulnerability in the view/about.php page
IDs: CVE-2024-34899, GHSA-f98p-2hc5-fm7v
Record: https://patchnext.com/advisories/cve-2024-34899 (revision 1, source checked 26 Oct 2026, 14:24 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: wwbn/avideo 14.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist wwbn/avideo: affected < 14.3; fixed in 14.3

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

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## 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-f98p-2hc5-fm7v (GitHub-reviewed advisory GHSA-f98p-2hc5-fm7v lists affected ranges: Packagist wwbn/avideo >=0 <14.3)

Commands are suggestions: review each one before running it.
