⚖️ Divergence & Operational Rationale

CVSS v3.1 rates CVE-2026-9048 at 4.3 Medium (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N). The Hermes Threat Score assesses it at 76 (MEDIUM). The risk is heightened in enterprise setups where sliders connect to corporate social channels, as exposed Instagram OAuth tokens, Flickr API keys, YouTube Data API keys, and Facebook App IDs permit secondary lateral movement and corporate impersonation.

Sensitive Cloud & Social Credential Leakage

CVSS v3.1: 4.3 Medium (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N) / CWE-200: Exposure of Sensitive Information to an Unauthorized Actor. Affects Slider Revolution versions 7.0.0 through 7.0.14. Fixed in 7.0.15. Allows authenticated Contributor-level users to extract unmasked third-party cloud and social API keys.

Executive Summary

CVE-2026-9048 is an information disclosure vulnerability in version 7.x of the Slider Revolution WordPress plugin. When querying slider configurations through the internal AJAX endpoint slider.get.full, the controller serialized the complete slider metadata JSON object back to the client.

Because the endpoint only required edit_posts permissions (Contributor level) and lacked data masking for sensitive fields, raw credentials stored in slider integration parameters—including Instagram OAuth access tokens, YouTube Data API keys, Flickr developer keys, and Facebook App IDs—are returned in plaintext JSON to low-privileged users.

Common Weakness Enumeration	CWE-200 (Information Exposure)	Unmasked API tokens in serialized slider settings
Network Vector	HTTP/HTTPS (80/TCP, 443/TCP)	Authenticated AJAX POST (Contributor+)

2. Vulnerability Mechanism

When slider.get.full is called:

// Vulnerable logic in Slider Revolution 7.x
public function get_slider_full( $slider_id ) {
    $slider_data = $this->get_slider_by_id( $slider_id );
    // FLAW: Entire settings object returned without stripping API secrets
    wp_send_json_success( $slider_data );
}

The returned JSON payload contains sensitive enterprise API keys:

{
  "success": true,
  "data": {
    "settings": {
      "instagram": { "token": "IGQVJ..." },
      "youtube": { "api_key": "AIzaSy..." },
      "facebook": { "app_id": "987654321", "app_secret": "ab12cd34..." }
    }
  }
}

3. Remediation Playbook

1. Update Slider Revolution to 7.0.15: Update immediately via the WordPress dashboard or FTP.
2. Rotate Exposed API Credentials: Regenerate all Instagram OAuth tokens, YouTube API keys, and Facebook App Secrets configured within slider instances.
