By crafting malicious XML content that exploits inefficient regular expression complexity used in the parsing process, an attacker can cause a denial-of-service (DoS) condition. This vulnerability allows for the system to hang and consume significant resources, potentially rendering services that utilize Scrapy for XML processing unresponsive.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-1333"],"references":["https://github.com/scrapy/scrapy/commit/479619b340f197a8f24c5db45bc068fb8755f2c5","https://huntr.com/bounties/271f94f2-1e05-4616-ac43-41752389e26b","https://github.com/scrapy/scrapy/commit/479619b340f197a8f24c5db45bc068fb8755f2c5","https://huntr.com/bounties/271f94f2-1e05-4616-ac43-41752389e26b"],"products":["scrapy:scrapy"],"source":"nvd","synced_at":"2026-10-19T21:45:59.823092188+00:00"},"epss":{"cve":"CVE-2024-1892","score":0.00557,"percentile":0.46473,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cc65-xxvf-f7r9","url":"https://osv.dev/vulnerability/GHSA-cc65-xxvf-f7r9","summary":"Scrapy vulnerable to ReDoS via XMLFeedSpider","modified":"2025-01-14T17:20:10.367591Z","packages":[{"ecosystem":"PyPI","name":"scrapy","purl":"pkg:pypi/scrapy","ranges":[">=2 <2.11.1"],"fixed":["2.11.1"]},{"ecosystem":"PyPI","name":"scrapy","purl":"pkg:pypi/scrapy","ranges":["<1.8.4"],"fixed":["1.8.4"]}]},{"id":"PYSEC-2024-162","url":"https://osv.dev/vulnerability/PYSEC-2024-162","summary":"","modified":"2026-06-10T17:02:40.004499262Z","packages":[{"ecosystem":"PyPI","name":"scrapy","purl":"pkg:pypi/scrapy","ranges":["<2.11.1"],"fixed":["2.11.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
