CVE-2026-105805 · Severity: medium · CVSS 4 · Published 2026-10-06

Payload is a headless CMS and database platform used to build content management systems. An attacker with access to query collections could manipulate sort parameters to leak information about protected fields they were not authorized to see. This allows unauthorized disclosure of sensitive data fields through sort query manipulation.

Technologies: [payload (npm)](https://junglewise.ai/threats/technologies/payload), [Payload CMS Payload](https://junglewise.ai/threats/technologies/payload-cms-payload). Vendors: [npm](https://junglewise.ai/threats/vendors/npm), [Payload CMS](https://junglewise.ai/threats/vendors/payload-cms).

## Quick answers

**Is CVE-2026-105805 exploited in the wild?** No. Junglewise Threat Intelligence has no report of CVE-2026-105805 being exploited in the wild.

**How severe is CVE-2026-105805?** Medium severity, with a CVSS score of 4, published 6 October 2026.

## How to fix

- payload (npm): upgrade to 3.88.0 or later

  ```sh
  npm install payload@3.88.0
  ```


Prevent untrusted users from controlling sort parameters, or restrict their query access to collections without protected fields until upgrading.

## Technical details

The vulnerability is an authorization bypass (CWE-863) in field-level access controls. Payload failed to validate field-level permissions on sort parameters before executing queries, allowing information disclosure (CWE-200) about protected fields. Attack vector is network with no authentication required; the precondition is that the attacker must have general query access to a collection and be able to control sort parameters.

## Affected products
