CVE-2026-1072: Keybase.io Verification <= 1.4.5 - Cross-Site Request Forgery to Settings Update

The Keybase.io Verification plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4.5. This is due to missing nonce validation when updating plugin settings. This makes it possible for unauthenticated attackers to update the Keybase verification text via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Security readout for executives and security teams

Plain-English summary

This affects the Keybase.io Verification WordPress plugin through version 1.4.5. A malicious site or link could trick a logged-in administrator into changing the plugin’s Keybase verification text. The business impact is limited integrity risk, not data theft or service outage based on current sources.

Executive priority

Handle during normal vulnerability remediation unless the plugin supports an important identity or trust workflow. Prioritize exposed public WordPress sites with many administrators or weak admin browsing practices.

Technical view

CVE-2026-1072 is a CSRF flaw caused by missing nonce validation during plugin settings updates. An unauthenticated attacker needs administrator interaction to submit a forged request that updates Keybase verification text. CVSS 3.1 is 4.3, with network access, low complexity, no privileges, and required user interaction.

Likely exposure

WordPress sites running Keybase.io Verification plugin versions up to and including 1.4.5 are the relevant exposure. Sites without this plugin, or not using affected versions, are not indicated as exposed by the provided sources.

Exploitation context

No active exploitation is stated in the provided sources, and the CVE is not listed as KEV. Exploitation requires social engineering of a logged-in site administrator, such as convincing them to click a malicious link.

Researcher notes

Sources identify CWE-352 and missing nonce validation in the settings update path. The bundle references WordPress Trac source and a changeset, but does not clearly name a fixed release. Do not assume active exploitation or broader impact beyond settings integrity.

Mitigation direction

  • Inventory WordPress sites for the Keybase.io Verification plugin and its version.
  • Update the plugin if a patched version is available from WordPress or the vendor.
  • If no patch is available, consider disabling the plugin if not business-critical.
  • Warn administrators not to click untrusted links while logged into WordPress.
  • Review and reset the Keybase verification text if unexpected changes are found.

Validation and detection

  • Confirm whether the plugin is installed on each WordPress site.
  • Check whether the installed version is 1.4.5 or earlier.
  • Review plugin settings for unauthorized Keybase verification text changes.
  • Review the referenced WordPress Trac code and changeset for nonce validation status.
  • Monitor Wordfence, CVE, and WordPress plugin sources for updated remediation guidance.
