CVE-2026-105805: CWE-200: Exposure of Sensitive Information to an Unauthorized Actor in payloadcms payload
Description
### Impact Under certain conditions, sorting readable records could reveal limited information about fields the requester was not permitted to read. You are affected if untrusted users can query a collection, control its sorting, and sort by protected fields. ### Patches Payload now applies field-level access checks to sort fields before executing queries. Users should upgrade to `>= 3.88.0` or `>= 4.0.0-canary.27`. ### Workarounds Upgrading is recommended. Until then, prevent untrusted users from controlling sort parameters or restrict their access to affected collections.

Technical Analysis
Payload CMS, a headless content management system, has a vulnerability (CVE-2026-105805) where an untrusted user who can query a readable collection and control its sorting can select a protected field as the sort parameter to infer limited information about field values that the user is not authorized to read. This exposure of sensitive information is classified under CWE-200 and CWE-863. The vulnerability affects versions prior to 3.88.0 and canary versions from 4.0.0-canary.0 up to but not including 4.0.0-canary.27. The issue is resolved in versions 3.88.0 and 4.0.0-canary.27.
Potential Impact
An unauthorized actor can infer limited sensitive information from protected fields by manipulating sorting parameters in queries on readable collections. This does not grant direct read access to protected data but leaks some information about field values, potentially aiding further attacks or information gathering.
Mitigation Recommendations
Upgrade Payload CMS to version 3.88.0 or later, or to canary version 4.0.0-canary.27 or later, where this vulnerability has been fixed. No other mitigation is indicated by the vendor advisory.
