# CVE-2026-41478: Saltcorn: SQL Injection via Unparameterized Sync Endpoints (maxLoadedId)

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (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 0.4% , percentile 37: FIRST’s model estimates a 0.4% chance of exploitation activity in the next 30 days, higher than 37% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes @saltcorn/server (npm) < 1.4.6, fixed in 1.4.6 ; @saltcorn/server (npm) >= 1.5.0-beta.0, < 1.5.6, fixed in 1.5.6 ; @saltcorn/server (npm) >= 1.6.0-alpha.0, < 1.6.0-beta.5, fixed in 1.6.0-beta.5 . Check your lockfile, including transitive dependencies.

## What it is

Saltcorn is an extensible, open source, no-code database application builder. Prior to 1.4.6, 1.5.6, and 1.6.0-beta.5, a SQL injection vulnerability in Saltcorn’s mobile-sync routes allows any authenticated low-privilege user with read access to at least one table to inject arbitrary SQL through sync parameters. This can lead to full database exfiltration, including admin password hashes and configuration secrets, and may also enable database modification or destruction depending on the backend. This vulnerability is fixed in 1.4.6, 1.5.6, and 1.6.0-beta.5.

## Affected packages

- npm `@saltcorn/server` < 1.4.6 → fixed: 1.4.6
- npm `@saltcorn/server` >= 1.5.0-beta.0, < 1.5.6 → fixed: 1.5.6
- npm `@saltcorn/server` >= 1.6.0-alpha.0, < 1.6.0-beta.5 → fixed: 1.6.0-beta.5

## Affected products (CVE record)

- saltcorn saltcorn: < 1.4.6, >= 1.5.0-beta.0, < 1.5.6, >= 1.6.0-alpha.0, < 1.6.0-beta.5

## Severity

- GitHub_M CVSS 3.1: 10 `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.9 `CVSS:3.1/AV:N/AC:L/PR:L/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 no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.44% probability of exploitation activity in the next 30 days; percentile 37.
