Full Report
SQL Injection vulnerability (CVE-2026-63316) has been found in Payload CMS software.
Analysis Summary
# Vulnerability: SQL Injection in Payload CMS Query Parameters
## CVE Details
- **CVE ID:** CVE-2026-63316
- **CVSS Score:** Not explicitly listed in source (Typically High for SQLi)
- **CWE:** CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
## Affected Systems
- **Products:** Payload CMS
- **Versions:**
- All versions prior to 3.90.0
- Versions 4.0.0-canary.0 through 4.0.0-canary.34
- **Configurations:** Systems using query filters where user input is passed to database operations.
## Vulnerability Description
A SQL injection vulnerability exists in Payload CMS due to the improper neutralization of user-supplied input within specific query parameters. Specifically, the software fails to adequately sanitize inputs provided to the `in` and `not_in` operators. This allows an authenticated attacker to manipulate database queries, potentially leading to unauthorized data access or modification.
## Exploitation
- **Status:** Reported via coordinated disclosure; no mention of active exploitation in the wild in the provided source.
- **Complexity:** Low to Medium (requires authenticated access).
- **Attack Vector:** Network (Remote).
## Impact
- **Confidentiality:** High (Potential to read sensitive database content).
- **Integrity:** High (Potential to modify or delete database records).
- **Availability:** Medium to High (Potential to disrupt database services).
## Remediation
### Patches
The vendor has released updates to address this flaw. Users should upgrade to the following versions or newer:
- **Version 3.90.0**
- **Version 4.0.0-canary.35** (Fixes the 4.0.0-canary.34 branch)
### Workarounds
No specific configuration workarounds were provided. The primary recommendation is a software update.
## Detection
- **Indicators of Compromise:** Unusual SQL syntax errors in application logs, specifically those involving the `in` or `not_in` operators. Unexpected database performance spikes or unauthorized data exfiltration patterns.
- **Detection methods and tools:** Web Application Firewalls (WAF) can be configured to detect and block common SQL injection patterns (e.g., `'`, `--`, `UNION SELECT`) within query string parameters.
