How to Fix CVE-2026-105856

To remediate this vulnerability, upgrade all affected Payload dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@payloadcms/db-sqlite fixed: 3.90.0 
npm install @payloadcms/db-sqlite@3.90.0
@payloadcms/db-d1-sqlite fixed: 3.90.0 
npm install @payloadcms/db-d1-sqlite@3.90.0
@payloadcms/db-postgres fixed: 3.73.0 
npm install @payloadcms/db-postgres@3.73.0
@payloadcms/db-vercel-postgres fixed: 3.73.0 
npm install @payloadcms/db-vercel-postgres@3.73.0
@payloadcms/db-sqlite fixed: 4.0.0-canary.34 
npm install @payloadcms/db-sqlite@4.0.0-canary.34
@payloadcms/db-d1-sqlite fixed: 4.0.0-canary.34 
npm install @payloadcms/db-d1-sqlite@4.0.0-canary.34
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @payloadcms/db-sqlite

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-105856, inspect your project dependencies using npm:

npm ls @payloadcms/db-sqlite

Analyze the terminal output to locate any version of Payload in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.90.0), your application is affected.

Note: The npm ls @payloadcms/db-sqlite command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), where the product constructs all or part of an sql command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended sql command when it is sent to a downstream component. without sufficient removal or quoting of sql syntax in user-controllable inputs, the generated sql query can cause those inputs to be interpreted as sql instead of ordinary user data. In Payload, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact An attacker who has read plus create or update access to a collection can submit a request that includes a SQL injection targeting a specific field path shape and operators in Payload's SQLite and Postgres. #### You are affected if: - You use `@payloadcms/db-sqlite` or `@payloadcms/db-d1-sqlite`. - You use `@payloadcms/db-postgres` or `@payloadcms/db-vercel-postgres` `< 3.73.0`. - A readable collection has a `json` field, or a` blocks` field with `blocksAsJSON: true`. - The attacker has read plus create or update access on it. #### You are not affected if: - You have no `json or `blocksAsJSON` fields. `richText` is not affected. - You run a patched version. ### Patches The patched version sanitizes the query input to prevent injection. Users should upgrade Payload packages to `>= 3.90.0` or `>= 4.0.0-canary.34`.
