Executive Summary

CVE-2026-22203 is an information disclosure vulnerability in wpDiscuz versions before 7.6.47. It occurs because the plugin allows administrators to export plugin options as JSON files, which unintentionally include sensitive OAuth secrets in plaintext.

These secrets include API credentials such as fbAppSecret, googleClientSecret, twitterAppSecret, and other social login credentials. Attackers can obtain these exported files from sources like support tickets, backups, or version control repositories.

The vulnerability requires administrator privileges but no user interaction and can be exploited remotely with low attack complexity.

Impact Analysis

This vulnerability can lead to unauthorized disclosure of sensitive OAuth credentials, such as API secrets for Facebook, Google, and Twitter integrations.

If attackers gain access to these secrets, they could potentially misuse social login credentials, impersonate users, or access connected services, leading to compromised accounts or data breaches.

Since the vulnerability requires administrator access to export the options, the risk is higher if an attacker already has elevated privileges or can access exported files through backups or support channels.

Mitigation Strategies

The immediate step to mitigate this vulnerability is to upgrade the wpDiscuz plugin to version 7.6.47 or later, where the issue has been fixed.

Additionally, review and remove any exported JSON files that contain sensitive OAuth secrets from support tickets, backups, or version control repositories to prevent unauthorized access.

Limit administrator access to trusted personnel only, as the vulnerability requires high privileges to exploit.
