RWKV7 Tokenizer eval() RCE — Proof of Concept

⚠️ SECURITY RESEARCH — DO NOT USE IN PRODUCTION ⚠️

This repository demonstrates CVE-pending arbitrary code execution via eval() in keras_hub.models.RWKV7Tokenizer vocabulary loading.

Vulnerability

keras_hub/src/models/rwkv7/rwkv7_tokenizer.py lines 117 and 275 call eval() on each line of vocabulary.txt during preset loading. The vocabulary file in this repo contains a payload that executes touch /tmp/keras_hub_rwkv7_pwned to prove code execution.

Trigger

python

import keras_hub
tokenizer = keras_hub.models.RWKV7Tokenizer.from_preset(
    "hf://d3banjan/rwkv7-tokenizer-eval-rce-poc"
)
# Check: ls -la /tmp/keras_hub_rwkv7_pwned

Fix

Replace eval() with ast.literal_eval() at lines 117 and 275.
