Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal via the deleteFile function. An attacker can delete arbitrary files or directories on the server by sending specially crafted HTTP requests containing encoded path traversal sequences. PoC !/usr/bin/env bash Delete a...

CVE-2026-34786

A flaw was found in Rack. A remote attacker can exploit this vulnerability by sending a specially crafted request with a URL-encoded static path. This bypasses security-relevant response headers intended for static content, potentially leading to information disclosure or other unintended...

CVE-2026-31402 nfsd: fix heap overflow in NFSv4.0 LOCK replay cache

In the Linux kernel, the following vulnerability has been resolved: nfsd: fix heap overflow in NFSv4.0 LOCK replay cache The NFSv4.0 replay cache uses a fixed 112-byte inline buffer rpibufNFSD4REPLAYISIZE to store encoded operation responses. This size was calculated based on OPEN responses and...

Rack has Content-Length mismatch in Rack::Files error responses

Summary Rack::Filesfail sets the Content-Length response header using Stringsize instead of Stringbytesize. When the response body contains multibyte UTF-8 characters, the declared Content-Length is smaller than the number of bytes actually sent on the wire. Because Rack::Files reflects the...

GHSA-Q4QF-9J86-F5MH Rack:: Static header_rules bypass via URL-encoded paths

Summary Rack::Staticapplicablerules evaluates several headerrules types against the raw URL-encoded PATHINFO, while the underlying file-serving path is decoded before the file is served. As a result, a request for a URL-encoded variant of a static path can serve the same file without the headers...
