Miggo AIRoot Cause Analysis

The provided vulnerability reports and advisories describe an XSS vulnerability via crafted URLs in Jenkins core but do not include specific code references, commit diffs, or patch details. While the general mechanism involves improper input sanitization in URL handling, the lack of technical specifics about the exact functions/files responsible for parsing URLs or rendering content makes it impossible to identify concrete vulnerable functions with high confidence. XSS vulnerabilities typically involve missing output encoding in web rendering components, but without access to the pre-patch code or patch changes, we cannot definitively pinpoint specific functions.
