GHSA-h7wm-ph43-c39p · Severity: high · Ecosystem: pip — Scrapy denial of service vulnerability
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.
Conclusion & alert: CVE-2017-14158 is rated High Exploit Risk (72.4/100): CVSS High severity, with medium exploitation likelihood (EPSS 1.91%). Core evidence: 1 public exploit reference(s) are indexed (Exploit-DB). Mandatory action: Public exploits are available—assess exposure, apply mitigations, and prioritize patching.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
