CVE-2026-41843Network attack vector

File disclosure via versioned resource path stripping

Published Jun 9, 2026 · Updated Jun 9, 2026

Path traversal in affected Spring Framework releases allows remote attackers to read files outside configured static-resource locations. The versioned resource resolver removes repeated instances of guessed version metadata from a request path instead of only the final content-version suffix, allowing resolution outside the configured location. Exposure requires Spring MVC or WebFlux to serve file-system resources with versioning enabled and the attacker to know or guess the target resource metadata.
