How to Fix CVE-2025-25298

To remediate this vulnerability, upgrade all affected @strapi/core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@strapi/core fixed: 5.10.3 
npm install @strapi/core@5.10.3
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @strapi/core

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2025-25298, inspect your project dependencies using npm:

npm ls @strapi/core

Analyze the terminal output to locate any version of @strapi/core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.10.3), your application is affected.

Note: The npm ls @strapi/core command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-261: Weak Encoding for Password, where obscuring a password with a trivial encoding does not protect the password. In @strapi/core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Summary Strapi's password hashing implementation using bcryptjs lacks maximum password length validation. Since bcryptjs truncates passwords exceeding 72 bytes, this creates potential vulnerabilities such as authentication bypass and performance degradation. ## POC Create an admin user with a password exceeding 72 characters like 85, Log in using only the first 72 characters of the password. Authentication is successful, confirming the issue. Proposed Solution Based on discussions: Add a maximum password length validation (72 characters) during password creation and updates for both Admin and U&P users. Truncate passwords exceeding 72 bytes on the server before passing them to bcryptjs during login. Optionally, issue a warning to users with passwords longer than 72 bytes during login, informing them of truncation. ## Impact This issue affects all Strapi installations using bcryptjs for password hashing. Until resolved, it can lead to: Authentication Bypass: Users may unknowingly set passwords exceeding 72 bytes, leading to truncated, predictable hashes. Performance Issues: Excessively long passwords can degrade server performance.
