# CVE-2023-52311: PaddlePaddle command injection in _wget_download

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (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 1.2% , percentile 67: FIRST’s model estimates a 1.2% chance of exploitation activity in the next 30 days, higher than 67% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Needs a user to click or open something. Phishing makes that realistic, but it is not wormable.
- Only applies if your dependency tree includes PaddlePaddle (PyPI) < 2.6.0, fixed in 2.6.0 . Check your lockfile, including transitive dependencies.

## What it is

PaddlePaddle before 2.6.0 has a command injection in wgetdownload. This resulted in the ability to execute arbitrary commands on the operating system.

## Affected packages

- PyPI `PaddlePaddle` < 2.6.0 → fixed: 2.6.0

## Affected products (CVE record)

- PaddlePaddle PaddlePaddle: < 2.6.0

## Severity

- Baidu CVSS 3.1: 9.6 `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.6 `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H`

## Exploitation

- 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): 1.18% probability of exploitation activity in the next 30 days; percentile 67.
