Summary

CVE-2025-65960 is a medium-severity Insufficient Type Distinction (CWE-351) vulnerability in Contao Contao. Its CVSS base score is 6.6 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and AC-16 (Security and Privacy Attributes) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation can reject or correctly classify data whose type is ambiguous or incorrect, stopping the weakness at entry points.

AC-16 Security and Privacy Attributes partial match

Associating security and privacy attributes with objects supplies the mechanism needed to distinguish element types and enforce handling rules.

AC-4 Information Flow Enforcement partial match

Information flow enforcement requires explicit rules that distinguish information types or categories before permitting transfer.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent type-distinction flaws during development while the control addresses the full lifecycle.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect type confusion vulnerabilities before deployment.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle practices can include type-safe design and validation to reduce type confusion.

A.8.26 Application security requirements partial match
prevents

Application security requirements can mandate explicit type handling and validation rules.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles encourage strong typing and clear type boundaries in system design.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly address proper type distinction and validation to prevent type-related flaws.
