CVE-2023-2079: Buy Me a Coffee – Button and Widget Plugin <= 3.7 - Cross-Site Request Forgery

The "Buy Me a Coffee – Button and Widget Plugin" plugin for WordPress is vulnerable to Cross-Site Request Forgery due to missing nonce validation on the recieve_post, bmc_disconnect, name_post, and widget_post functions in versions up to, and including, 3.7. This makes it possible for unauthenticated attackers to update the plugins settings, via a forged request granted the attacker can trick a site's administrator into performing an action such as clicking on a link.

Security readout for executives and security teams

Plain-English summary

This WordPress plugin flaw lets an attacker change Buy Me a Coffee plugin settings if they can trick a site administrator into taking an action, such as following a crafted link. It is not listed in KEV and requires administrator interaction, but the impacted setting changes could affect site integrity, confidentiality, and availability.

Executive priority

Prioritize remediation for public WordPress sites using this plugin, especially where administrators frequently access email or external links from authenticated sessions. Treat as high priority, not emergency, unless local evidence shows compromise.

Technical view

CVE-2023-2079 is a CSRF issue in Buy Me a Coffee – Button and Widget Plugin versions up to and including 3.7. Missing nonce validation affects recieve_post, bmc_disconnect, name_post, and widget_post. The CVSS 3.1 score is 7.1, with network attack vector, low complexity, no privileges, and required user interaction.

Likely exposure

Exposure is limited to WordPress sites running the Buy Me a Coffee – Button and Widget Plugin at version 3.7 or earlier. The source bundle does not identify broader affected products or confirmed exploitation.

Exploitation context

The attacker must cause a logged-in site administrator to perform an action. The vulnerability is not marked in CISA KEV in the provided data, so active exploitation should not be assumed.

Researcher notes

The provided record names vulnerable functions and CSRF root cause, but does not include a detailed patch description or exploitation evidence. Validate nonce and capability protections in the referenced WordPress.org code changes before closing remediation.

Mitigation direction

  • Inventory WordPress sites for the Buy Me a Coffee plugin and installed version.
  • Update, disable, or remove affected plugin installations according to vendor guidance.
  • Restrict administrator browsing and discourage unsolicited links while remediation is pending.
  • Review plugin settings for unauthorized changes after exposure windows.

Validation and detection

  • Confirm whether the plugin is installed on each WordPress site.
  • Verify installed versions are not up to and including 3.7.
  • Review administrative activity around plugin settings changes.
  • Check vendor or WordPress.org changelog for the CVE-specific fix.
