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.","lang":"en"}],"references":[{"url":"https://security.snyk.io/vuln/SNYK-GOLANG-GITHUBCOMYUINGOLDMARKRENDERERHTML-15838406"},{"url":"https://github.com/yuin/goldmark/commit/cb46bbc4eca29d55aa9721e04ad207c23ccc44f9"}],"affected":[{"product":"github.com/yuin/goldmark/renderer/html","versions":[{"version":"0","lessThan":"1.7.17","status":"affected","versionType":"semver"}],"vendor":"n/a"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-15T18:07:02.033634Z","id":"CVE-2026-5160","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-04-15T18:07:10.025Z"}}]}}
