# CVE-2024-47175: libppd's ppdCreatePPDFromIPP2 function does not sanitize IPP attributes when creating the PPD buffer

**Signal:** High exploit likelihood. EPSS ranks it in the top 5% of all CVEs for likely exploitation in the next 30 days. (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 63.6% , percentile 99: FIRST’s model estimates a 63.6% chance of exploitation activity in the next 30 days, higher than 99% of all scored CVEs (very high). 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 is a standards-based, open-source printing system, and libppd can be used for legacy PPD file support. The libppd function ppdCreatePPDFromIPP2 does not sanitize IPP attributes when creating the PPD buffer. When used in combination with other functions such as cfGetPrinterAttributes5, can result in user controlled input and ultimately code execution via Foomatic. This vulnerability can be part of an exploit chain leading to remote code execution (RCE), as described in CVE-2024-47176.

## Affected products (CVE record)

- OpenPrinting libppd: <= 2.1b1

## Severity

- GitHub_M CVSS 3.1: 8.6 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 63.61% probability of exploitation activity in the next 30 days; percentile 99.
