{"id":"AZL-44202","summary":"CVE-2020-7662 affecting package js-jquery 3.5.0-4","details":"websocket-extensions npm module prior to 0.1.4 allows Denial of Service (DoS) via Regex Backtracking. The extension parser may take quadratic time when parsing a header containing an unclosed string parameter value whose content is a repeating two-byte sequence of a backslash and some other character. This could be abused by an attacker to conduct Regex Denial Of Service (ReDoS) on a single-threaded server by providing a malicious payload with the Sec-WebSocket-Extensions header.","modified":"2026-04-01T05:15:30.519938Z","published":"2020-06-02T19:15:12Z","upstream":["CVE-2020-7662"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-7662"}],"affected":[{"package":{"name":"js-jquery","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/js-jquery"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"3.5.0-4"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-44202.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
