Authenticated file disclosure via document-root traversal
Published Mar 26, 2026 · Updated Mar 26, 2026
Path traversal in Smallsrv Small HTTP Server 3.06.36 allows remote authenticated users to read files outside the document root. Requests to / bypass SecurityManager's document-root restriction, but INCIBE has not disclosed the exact path-normalization error or crafted syntax. Exploitation requires valid server credentials and filesystem permission to the target file; the bounded result is file disclosure.
