# CVE-2026-52887: NocoBase: SQL injection in /api/myInAppChannels:list filter to PG-superuser RCE

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.9% , percentile 59: FIRST’s model estimates a 0.9% chance of exploitation activity in the next 30 days, higher than 59% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes @nocobase/plugin-notification-in-app-message (npm) <= 2.0.60, fixed in 2.0.61 . Check your lockfile, including transitive dependencies.

## What it is

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.

## Affected packages

- npm `@nocobase/plugin-notification-in-app-message` <= 2.0.60 → fixed: 2.0.61

## Affected products (CVE record)

- nocobase nocobase: < 2.0.61

## Severity

- GitHub_M CVSS 3.1: 10 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 10.0 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.89% probability of exploitation activity in the next 30 days; percentile 59.
