Last modified Jun 17, 2026

CVE-2017-14158 is a vulnerability of currently unknown severity. Scrapy 1.4 allows remote attackers to cause a denial of service (memory consumption) via large files because arbitrarily many files are read into memory, which is especially problematic if the files are then individually written in a separate thread to a slow storage resource, as demonstrated by interaction between dataReceived (in core/downloader/handlers/http11.py) and S3FilesStore.. EPSS estimates a 1.91% chance of exploitation in the next 30 days.
