Security readout for executives and security teams
Plain-English summary
This is a stored cross-site scripting issue in the WordPress My YouTube Channel plugin. An administrator-level user could save malicious script through plugin settings, causing it to run when affected pages are viewed. Business risk is limited by the high privilege required, but it matters if admin accounts are compromised or shared.
Executive priority
Handle as a moderate-priority WordPress hygiene issue. It is not shown as actively exploited and needs admin privileges, but affected sites should be remediated promptly because stored XSS can persist and affect users who view impacted pages.
Technical view
CVE-2023-0446 is CWE-79 in My YouTube Channel versions up to and including 3.0.12.1. Settings parameters lack sufficient input sanitization and output escaping, allowing administrator-plus authenticated stored XSS. CVSS 3.1 is 5.5 with network access, low complexity, high privileges required, changed scope, and low confidentiality/integrity impact.
Likely exposure
Likely exposure is WordPress sites with My YouTube Channel installed at version 3.0.12.1 or earlier. Practical exposure is narrower because exploitation requires administrator-level access, but compromised admin credentials could turn this into a persistent browser-side risk.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation evidence. The issue is post-authentication and administrator-level, so it is more relevant to insider misuse, compromised admin accounts, or weak admin governance than unauthenticated mass exploitation.
Researcher notes
The bundle’s affected metadata is incomplete or inconsistent, but the description and title identify versions up to and including 3.0.12.1. No exploit details, KEV status, or definite fixed version are provided in the supplied evidence.
Mitigation direction
- Inventory WordPress sites for My YouTube Channel and installed plugin versions.
- Check vendor, WordPress plugin, or Wordfence guidance for the fixed release before upgrading.
- Disable or remove the plugin if it is unnecessary or cannot be verified fixed.
- Restrict administrator access and enforce MFA for WordPress admin accounts.
- Review plugin settings for unexpected script, HTML, or recently changed values.
Validation and detection
- Confirm whether any site runs My YouTube Channel version 3.0.12.1 or earlier.
- Review WordPress admin audit logs for recent plugin settings changes.
- Inspect affected pages for unexpected script execution sourced from plugin settings.
- Check whether administrator accounts are shared, stale, or recently compromised.
- Document current plugin status, version, and remediation decision for each site.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
