CVE-2026-34746: CWE-918: Server-Side Request Forgery (SSRF) in payloadcms payload
PayloadCMS versions prior to 3.79.1 contain an authenticated Server-Side Request Forgery (SSRF) vulnerability in the upload functionality. Authenticated users with create or update permissions on upload-enabled collections can cause the server to make arbitrary outbound HTTP requests. This vulnerability has been addressed in version 3.79.1. The CVSS score is 7.7, indicating high severity due to the potential for server-side request manipulation without impacting data integrity or availability directly.
AI Analysis
Technical Summary
CVE-2026-34746 describes an SSRF vulnerability (CWE-918) in PayloadCMS before version 3.79.1. The flaw allows authenticated users with specific upload permissions to trigger outbound HTTP requests from the server to arbitrary URLs via the upload feature. This can lead to information disclosure or interaction with internal network resources. The vulnerability requires authentication and privileges to create or update upload-enabled collections. The issue has been fixed in PayloadCMS version 3.79.1.
Potential Impact
An attacker with authenticated access and appropriate permissions can exploit this SSRF vulnerability to make the server perform HTTP requests to arbitrary external or internal URLs. This could potentially expose internal services or sensitive information accessible only from the server's network. The vulnerability does not directly affect data integrity or availability but poses a significant risk of information disclosure or network reconnaissance.
Mitigation Recommendations
Upgrade PayloadCMS to version 3.79.1 or later, where this SSRF vulnerability has been patched. No other mitigations are indicated or required once the official fix is applied.
