CVSS 10.0 Critical EPSS 7.4% · p94
Should you act?
Critical and remotely reachable
No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Not in CISA KEV, but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 7.4%, percentile 94: FIRST’s model estimates a 7.4% chance of exploitation activity in the next 30 days, higher than 94% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes
paperclipai(npm) < 2026.410.0, fixed in 2026.410.0;@paperclipai/server(npm) < 2026.410.0, fixed in 2026.410.0. Check your lockfile, including transitive dependencies.
What it is
Paperclip is a Node.js server and React UI that orchestrates a team of AI agents to run a business. Prior to version 2026.416.0, an unauthenticated attacker can achieve full remote code execution on any network-accessible Paperclip instance running in authenticated mode with default configuration. No user interaction, no credentials, just the target's address. The chain consists of six API calls. The attack is fully automated, requires no user interaction, and works against the default deployment configuration. Version 2026.416.0 patches the issue.
From the GitHub advisory
Summary
An unauthenticated attacker can achieve full remote code execution on any network-accessible Paperclip instance running in authenticated mode with default configuration. No user interaction, no credentials, just the target's address. The entire chain is six API calls.
I verified every step against the latest version. I have a fully automated PoC script and a video recording available.

CVSS measures how bad a flaw is if exploited, not how likely exploitation is. Read it next to the exploitation data below.
Exploitation and urgency
- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc, automatable yes, technical impact total.
- FIRST EPSS (model of 2026-10-21): 7.36% probability of exploitation activity in the next 30 days; percentile 94.
