Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-99j6-hj87-6fcf plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,333 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-99j6-hj87-6fcf can be triaged on real exposure rather than presence alone.
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 Security finds GHSA-99j6-hj87-6fcf across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
