{"id":"AZL-83060","summary":"CVE-2026-5160 affecting package telegraf for versions less than 1.31.0-19","details":"Versions of the package github.com/yuin/goldmark/renderer/html before 1.7.17 are vulnerable to Cross-site Scripting (XSS) due to improper ordering of URL validation and normalization. The renderer validates link destinations using a prefix-based check (IsDangerousURL) before resolving HTML entities. This allows an attacker to bypass protocol filtering by encoding dangerous schemes using HTML5 named character references. For example, a payload such as javascript:alert(1) is not recognized as dangerous during validation, leading to arbitrary script execution in the context of applications that render the URL.","modified":"2026-08-30T05:26:50Z","published":"2026-04-15T06:16:13Z","upstream":["CVE-2026-5160"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-5160"}],"affected":[{"package":{"name":"telegraf","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/telegraf"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.31.0-19"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-83060.json"}}],"schema_version":"1.9.0"}
