# CVE-2024-47850: OpenPrinting CUPS, cups-browsed vulnerability

**Signal:** Normal patch cycle. No exploitation signal; fix it in your next routine update if you are affected. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.9% , percentile 58: FIRST’s model estimates a 0.9% chance of exploitation activity in the next 30 days, higher than 58% of all scored CVEs (moderate). 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.
- Editorial verdict: Check exposure. CUPS cups-browsed RCE Chain: Real, but Needs a Print Job — Not the internet-ending bug the pre-disclosure hype suggested: code runs only when someone prints to the rogue printer, as the unprivileged lp user; but nothing should expose UDP 631 to the internet, and exposed hosts can be abused for DDoS.

## What it is

CUPS cups-browsed before 2.5b1 will send an HTTP POST request to an arbitrary destination and port in response to a single IPP UDP packet requesting a printer to be added, a different vulnerability than CVE-2024-47176. (The request is meant to probe the new printer but can be used to create DDoS amplification attacks.)

## Affected products (CVE record)

- n/a n/a: see advisory

## Severity

- CISA-ADP CVSS 3.1: 7.5 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable no , technical impact partial .
- FIRST EPSS (model of 2026-10-21): 0.85% probability of exploitation activity in the next 30 days; percentile 58.
