GHSA-99j6-hj87-6fcf
MEDIUMGHSA-99j6-hj87-6fcf is a medium-severity (CVSS 5.3) Information Exposure vulnerability in wwbn/avideo. O3 Security confirms whether GHSA-99j6-hj87-6fcf is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
AVideo: Unauthenticated Information Disclosure via Missing Auth on CloneSite client.log.php
Blast Radius
wwbn/avideoReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
Summary
The plugin/CloneSite/client.log.php endpoint serves the clone operation log file without any authentication. Every other endpoint in the CloneSite plugin directory enforces User::isAdmin(). The log contains internal filesystem paths, remote server URLs, and SSH connection metadata.
Details
The entire file at plugin/CloneSite/client.log.php:
<?php
include '../../videos/cache/clones/client.log';
No authentication check. The log file is populated by cloneClient.json.php which writes operational details during clone operations:
// plugin/CloneSite/cloneClient.json.php:118
$log->add("Clone (2 of {$totalSteps}): Geting MySQL Dump file [$cmd]");
The $cmd variable contains wget commands with internal filesystem paths, and rsync command templates with SSH connection details (username, IP, port).
Compare with sibling endpoints:
plugin/CloneSite/index.phpchecksUser::isAdmin()plugin/CloneSite/changeStatus.json.phpchecksUser::isAdmin()plugin/CloneSite/clones.json.phpchecksUser::isAdmin()plugin/CloneSite/delete.json.phpchecksUser::isAdmin()
Proof of Concept
curl "https://your-avideo-instance.com/plugin/CloneSite/client.log.php"
If the CloneSite feature has been used, the response contains wget commands, filesystem paths, SSH metadata, and SQL dump file locations.
Impact
Unauthenticated disclosure of internal infrastructure details that could aid targeted attacks against the clone source server.
Recommended Fix
Add an admin authentication check at plugin/CloneSite/client.log.php, before the include:
require_once '../../videos/configuration.php';
if (!User::isAdmin()) {
http_response_code(403);
die('Access denied');
}

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for wwbn/avideo. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of wwbn/avideo has shipped for GHSA-99j6-hj87-6fcf yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-99j6-hj87-6fcf is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-99j6-hj87-6fcf. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-99j6-hj87-6fcf in your dependencies?
O3 detects GHSA-99j6-hj87-6fcf across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
