{"id":"CVE-2024-1892","summary":"ReDoS Vulnerability in scrapy/scrapy's XMLFeedSpider","details":"A Regular Expression Denial of Service (ReDoS) vulnerability exists in the XMLFeedSpider class of the scrapy/scrapy project, specifically in the parsing of XML content. 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.","aliases":["GHSA-cc65-xxvf-f7r9","PYSEC-2024-162"],"modified":"2026-08-12T03:51:32.724681822Z","published":"2024-02-28T00:00:14.092Z","related":["openSUSE-SU-2024:13802-1"],"database_specific":{"cna_assigner":"@huntr_ai","cwe_ids":["CWE-1333"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/1xxx/CVE-2024-1892.json"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/scrapy/scrapy","events":[{"introduced":"0"},{"fixed":"2f1d345e74d19e33016f9e69fcda0bda9afb568d"},{"fixed":"479619b340f197a8f24c5db45bc068fb8755f2c5"}],"database_specific":{"cpe":"cpe:2.3:a:scrapy:scrapy:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2.11.1"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["2.11.0","2.10.0","2.9.0","2.8.0","2.7.1","2.7.0","2.6.1","2.6.0","1.8.0","2.5.0","2.4.0","2.3.0","2.2.0","2.1.0","2.0.0","1.7.0","1.6.0","1.5.0","1.4.0","1.3.2","1.3.1","1.2.2","1.3.0","1.2.1","1.2.0","1.2.0dev2","1.0.0rc1","scrapy-0.25.1-sc","hojo","0.25.1","0.24.0","0.25.0","0.23.0","0.21.0","0.17.0","0.15.1","0.14.0","0.15.0","0.10.3","0.10.2","0.10.1","0.10","0.10-rc1","0.9","0.9-rc1","0.8","0.7","0.7-rc1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-1892.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
