CVE-2026-41679: CWE-287: Improper Authentication in paperclipai paperclip
CVE-2026-41679 is a critical improper authentication vulnerability in Paperclip, a Node. js server and React UI platform for orchestrating AI agents. Prior to version 2026. 416. 0, an unauthenticated attacker can remotely execute arbitrary code on any network-accessible Paperclip instance running in authenticated mode with default configuration. The attack requires no user interaction or credentials and involves a chain of six API calls. The vulnerability is patched in version 2026. 416. 0.
AI Analysis
Technical Summary
Paperclip versions before 2026.416.0 contain an authentication bypass vulnerability (CWE-287) that allows unauthenticated remote code execution. The flaw affects instances running in authenticated mode with default settings. Exploitation involves a sequence of six API calls that an attacker can automate without user interaction or credentials. This vulnerability has a CVSS 3.1 base score of 10.0, indicating critical impact on confidentiality, integrity, and availability. The issue is resolved in version 2026.416.0.
Potential Impact
An attacker can achieve full remote code execution on vulnerable Paperclip instances without authentication or user interaction. This compromises confidentiality, integrity, and availability of the affected system. The vulnerability affects any network-accessible instance running in authenticated mode with default configuration prior to version 2026.416.0. No known exploits in the wild have been reported as of the published date.
Mitigation Recommendations
Upgrade Paperclip to version 2026.416.0 or later, which patches this vulnerability.
