{"id":"PYSEC-2024-162","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":["CVE-2024-1892","GHSA-cc65-xxvf-f7r9"],"modified":"2025-01-14T05:56:55.289794Z","published":"2024-02-28T00:15:53Z","references":[{"type":"WEB","url":"https://huntr.com/bounties/271f94f2-1e05-4616-ac43-41752389e26b"},{"type":"FIX","url":"https://github.com/scrapy/scrapy/commit/479619b340f197a8f24c5db45bc068fb8755f2c5"}],"affected":[{"package":{"name":"scrapy","ecosystem":"PyPI","purl":"pkg:pypi/scrapy"},"ranges":[{"type":"GIT","repo":"https://github.com/scrapy/scrapy","events":[{"introduced":"0"},{"fixed":"479619b340f197a8f24c5db45bc068fb8755f2c5"},{"fixed":"479619b340f197a8f24c5db45bc068fb8755f2c5"}]},{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.11.1"}]}],"versions":["0.10.4.2364","0.12.0.2550","0.14.1","0.14.2","0.14.3","0.14.4","0.16.0","0.16.1","0.16.2","0.16.3","0.16.4","0.16.5","0.18.0","0.18.1","0.18.2","0.18.3","0.18.4","0.20.0","0.20.1","0.20.2","0.22.0","0.22.1","0.22.2","0.24.0","0.24.1","0.24.2","0.24.3","0.24.4","0.24.5","0.24.6","0.7","0.8","0.9","1.0.0","1.0.0rc1","1.0.0rc2","1.0.0rc3","1.0.1","1.0.2","1.0.3","1.0.4","1.0.5","1.0.6","1.0.7","1.1.0","1.1.0rc1","1.1.0rc2","1.1.0rc3","1.1.0rc4","1.1.1","1.1.2","1.1.3","1.1.4","1.2.0","1.2.1","1.2.2","1.2.3","1.3.0","1.3.1","1.3.2","1.3.3","1.4.0","1.5.0","1.5.1","1.5.2","1.6.0","1.7.0","1.7.1","1.7.2","1.7.3","1.7.4","1.8.0","1.8.1","1.8.2","1.8.3","1.8.4","2.0.0","2.0.1","2.1.0","2.10.0","2.10.1","2.11.0","2.2.0","2.2.1","2.3.0","2.4.0","2.4.1","2.5.0","2.5.1","2.6.0","2.6.1","2.6.2","2.6.3","2.7.0","2.7.1","2.8.0","2.9.0"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/scrapy/PYSEC-2024-162.yaml"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
