CVE-2025-25298Missing Maximum Password Length Validation in Strapi Password Hashing
Medium 6.3
In plain English
A medium-severity security flaw in strapi from strapi. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 34% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
Strapi is an open source headless CMS. The @strapi/core package before version 5.10.3 does not enforce a maximum password length when using bcryptjs for password hashing. Bcryptjs ignores any bytes beyond 72, so passwords longer than 72 bytes are silently truncated. A user can create an account with a password exceeding 72 bytes and later authenticate with only the first 72 bytes. This reduces the effective entropy of overlong passwords and may mislead users who believe characters beyond 72 bytes are required, creating a low likelihood of unintended authentication if an attacker can obtain or guess the truncated portion. Long over‑length inputs can also impose unnecessary processing overhead. The issue is fixed in version 5.10.3. No known workarounds exist.
