CVE-2023-22894: @strapi/strapi Strapi Leaking Sensitive User Information Vulnerability
HIGHCVE-2023-22894 is a HIGH (CVSS 7.5) strapi leaking sensitive user information vulnerability (CWE-312: Cleartext Storage of Sensitive Information) affecting @strapi/strapi libraries in the npm ecosystem. The issue involves strapi leaking sensitive user information by filtering on private fields. Remediation is available by upgrading affected packages to version 4.8.0.
CVE-2023-22894 at a Glance
Security Impact
CVSS: 7.5
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
How to Fix CVE-2023-22894
To remediate this vulnerability, upgrade all affected @strapi/strapi dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install @strapi/strapi@4.8.0Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls @strapi/strapiHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2023-22894, inspect your project dependencies using npm:
npm ls @strapi/strapiAnalyze the terminal output to locate any version of @strapi/strapi in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.8.0), your application is affected.
Note: The npm ls @strapi/strapi command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

"details" : "### Summary\n\nStrapi through 4.7.1 allows unauthenticated attackers to discover sensitive user details for Strapi administrators and API users.\n\n### Details\n\nStrapi through 4.7.1 allows unauthenticated attackers to discover sensitive user details for Strapi administrators and API users. The unauthenticated attacker can filter users by columns that contain sensitive information and infer the values by the changes in the API responses. An unauthenticated attacker can exploit this vulnerability to hijack Strapi administrator accounts and gain unauthorized Strapi Super Administrator access by leaking the password reset token and changing the admin password. This can be exploited on all Strapi versions <=4.7.1.\n\n### IoC\n\nThe exploitation of CVE-2023-22894 is easily detectable, since the payload is within the GET parameters and are normally included in request logs. The following regex pattern will extract requests that are exploiting this vulnerability to leak user's email, password and password reset token columns.\n\n`/(\\[|%5B)\\s*(email|password|reset_password_token|resetPasswordToken)\\s*(\\]|%5D)/`\n\nYou can search log files for this IoC by using the following grep command.\n\n`grep -iE '(\\[|%5B)\\s*(email|password|reset_password_token|resetPasswordToken)\\s*(\\]|%5D)' $PATH_TO_LOG_FILE`\n\nIf the above regex pattern matches any lines in your log files, take extra precaution to look out for multiple requests that include password, reset_password_token or resetPasswordToken. This would indicate that an attacker has leaked the password hashes and reset tokens on your Strapi server and you need to immediately start an incident response!\n\n### Impact\n\nAll Strapi users below 4.8.0\n",
