CVE-2026-105845: CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in payloadcms payload
Description
### Impact A user can submit a request that exploits a SQL Injection vulnerability in Payload. You are affected if: - You use an affected Payload version. - Untrusted users can query readable collections using dynamic filters or joins. You are not affected if you use MongoDB (`@payloadcms/mongodb`). ### Patches Users should upgrade Payload packages to `>= 3.88.0` or `>= 4.0.0-canary.27`. ### Workarounds Upgrading to a patched version is recommended. Until you can upgrade, restrict untrusted users from supplying dynamic query filters or join parameters and limit read access to affected collections.

Technical Analysis
PayloadCMS, a headless content management system, has an SQL injection vulnerability (CWE-89) in versions >=3.0.0 <3.88.0 and >=4.0.0-canary.0 <4.0.0-canary.27. An untrusted user able to query readable collections through dynamic filters or joins can craft requests that cause SQL injection in the SQLite and Postgres database adapters. This allows execution of arbitrary SQL commands, impacting confidentiality, integrity, and availability. The issue is resolved in versions 3.88.0 and 4.0.0-canary.27.
Potential Impact
Successful exploitation can lead to full compromise of the database, including unauthorized data disclosure, data modification, or deletion, and potentially system compromise due to the critical nature of the vulnerability. The CVSS 3.1 score is 9.8 (critical), reflecting network attack vector, low attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Upgrade PayloadCMS to version 3.88.0 or later, or to 4.0.0-canary.27 or later for canary releases. These versions contain the official fix for the SQL injection vulnerability. No other mitigations are specified. Patch status is confirmed fixed in these versions.
