## Summary

SuiteCRM, an open-source customer relationship management application, has a mass assignment flaw in its V8 API that lets a logged-in user modify internal authentication fields such as password hashes and external-authentication flags, which can give them unauthorized account access. The flaw can be reached remotely over the network by any user with a low-privilege account, and no user interaction is needed.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- SuiteCRM: fixed in 7.15.2; from 8.0.0, fixed in 8.10.2

## Description

SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to 7.15.2 and 8.10.2, the V8 write path checks that a field exists but does not enforce api-visible or sensitive metadata that hides the same field on reads. The affected flow begins at PATCH /Api/V8/module and uses user_hash, external_auth_only, api-visible: false, and sensitive: true to carry attacker-controlled data or authorization state into the security-sensitive operation. An authenticated user can mass-assign internal authentication fields, modify password hashes or external-authentication flags, and persist unauthorized account access. This issue is fixed in versions 7.15.2 and 8.10.2.

## What to do

## FAQ

### Is CVE-2026-100361 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

### What does this mean?

The V8 REST API write path checks only that a field exists, not whether it is restricted. An authenticated user can therefore change hidden sensitive fields such as user_hash and external_auth_only, which may let them keep unauthorized account access.
