Security readout for executives and security teams
Plain-English summary
This is a medium-severity CSRF issue in the WordPress Big File Uploads plugin from Infinite Uploads, affecting versions <= 2.1.1. An attacker would need a user to interact with a malicious request. The reported impact is limited integrity change, not data theft or service outage. No active exploitation is cited in the supplied sources.
Executive priority
Treat as a routine but necessary WordPress hygiene item. It is not cited as actively exploited and has limited integrity impact, but exposed plugin installations should be found and remediated during the next maintenance cycle.
Technical view
CVE-2023-47792 is CWE-352 Cross-Site Request Forgery in the tuxedo-big-file-uploads WordPress plugin. CVSS 3.1 is 4.3: network reachable, low complexity, no attacker privileges, user interaction required, unchanged scope, low integrity impact, no confidentiality or availability impact. The bundle does not identify the exact vulnerable action or fixed version.
Likely exposure
Exposure is limited to WordPress sites running Infinite Uploads Big File Uploads - Increase Maximum File Upload Size plugin versions <= 2.1.1. The source bundle provides no CPEs and no default affected environment beyond the plugin package name.
Exploitation context
The sources describe CSRF only. Successful abuse would require tricking a relevant user into triggering an unintended authenticated action. KEV status is false, and the supplied sources do not report public exploitation or weaponized activity.
Researcher notes
Evidence is sparse. The bundle confirms CSRF, affected plugin, version threshold, CVSS, CWE, and Patchstack reference, but not the exact endpoint, nonce failure, required victim role, or fixed version. Avoid assuming exploitability details beyond CSRF with user interaction.
Mitigation direction
- Inventory WordPress sites for the tuxedo-big-file-uploads plugin.
- Identify any installed version <= 2.1.1.
- Check vendor, WordPress plugin, or Patchstack guidance for the fixed release.
- Update, disable, or remove the plugin based on vendor guidance.
- Limit administrative access to trusted users and managed devices.
Validation and detection
- Confirm the plugin name and installed version on each WordPress site.
- Verify whether the installed version is <= 2.1.1.
- Review vendor or Patchstack advisory details for remediation status.
- After remediation, confirm the vulnerable version is no longer deployed.
- Document sites where the plugin is absent or already remediated.

Cross-Site Request Forgery (CSRF)
Cross-Site Request Forgery (CSRF) represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
