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.","published":"2024-02-28T00:00:14.092Z","modified":"2026-08-12T03:51:32.724681822Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":{"score":0.00557,"percentile":0.45019,"asOf":"2026-09-16"},"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"PyPI","name":"scrapy","fixedVersion":"2.11.1"},{"ecosystem":"PyPI","name":"scrapy","fixedVersion":"1.8.4"}],"fix":{"url":"https://github.com/scrapy/scrapy/commit/479619b340f197a8f24c5db45bc068fb8755f2c5","label":"scrapy/scrapy@479619b"},"references":[{"type":"WEB","url":"https://huntr.com/bounties/271f94f2-1e05-4616-ac43-41752389e26b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/1xxx/CVE-2024-1892.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-1892"},{"type":"FIX","url":"https://github.com/scrapy/scrapy/commit/479619b340f197a8f24c5db45bc068fb8755f2c5"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:32.724681822Z"}}
