Summary

CVE-2025-25298 is a medium-severity Weak Encoding for Password (CWE-261) vulnerability in Strapi Strapi. Its CVSS base score is 6.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); ranked at the 31th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SC-13 (Cryptographic Protection) and IA-5 (Authenticator Management) — see the control section below for these in your framework.

Vulnerability Data

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.

Mitigating Controls (NIST 800-53 r5) AI

SC-13 Cryptographic Protection good match

Cryptographic protection mandates approved algorithms and key management that preclude weak encoding schemes for sensitive data such as passwords.

IA-5 Authenticator Management partial match

Authenticator management requires secure generation, storage, and distribution of passwords rather than trivial encoding.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.DS-01 mostly match
prevents

Proper cryptographic hashing for data-at-rest directly prevents trivial password encoding while the control addresses broader data protection needs.

A.8.24 Use of cryptography mostly match
prevents

Requires appropriate use of cryptography, indirectly discouraging weak encoding schemes.

A.5.17 Authentication information partial match
degrades

Requires secure handling and protection of authentication information, directly addressing weak password encoding.

A.8.28 Secure coding partial match
prevents

Enforces secure coding practices that would reject trivial password encoding.

A.8.5 Secure authentication partial match
degrades

Mandates secure authentication mechanisms, which precludes trivial encoding of passwords.
