CVE-2024-0243

Estado: AnalizadaAlta (8.1)—

Con la siguiente configuración del rastreador: ```python de bs4 import BeautifulSoup as Soup url = "https://example.com" loader = RecursiveUrlLoader( url=url, max_ Depth=2, extractor=lambda x: Soup(x, "html .parser").text ) docs = loader.load() ``` Un atacante que controle el contenido de `https://example.com` podría colocar un archivo HTML malicioso allí con enlaces como "https:/example.completely.different/my_file.html" y el rastreador procedería a descargar ese archivo también aunque `prevent_outside=True`. https://github.com/langchain-ai/langchain/blob/bf0b3cc0b5ade1fb95a5b1b6fa260e99064c2e22/libs/community/langchain_community/document_loaders/recursive_url_loader.py#L51-L51 Resuelto en https://github.com/langchain-ai/langchain/pull /15559

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
