Traefik Vulnerable to BasicAuth/DigestAuth Identity Spoofing via Non-Canonical headerField in github.com/traefik/traefik...

PT-2026-29922

Summary Rack::Sendfilemap accel path interpolates the value of the X-Accel-Mapping request header directly into a regular expression when rewriting file paths for X-Accel-Redirect. Because the header value is not escaped, an attacker who can supply X-Accel-Mapping to the backend can inject regex...

Rack - Forwarded Header semicolon injection enables Host and Scheme spoofing

Summary Rack::Utils.forwardedvalues parses the RFC 7239 Forwarded header by splitting on semicolons before handling quoted-string values. Because quoted values may legally contain semicolons, a header such as: http Forwarded: for="127.0.0.1;host=evil.com;proto=https" can be interpreted by Rack as...

Rack's improper unfolding of folded multipart headers preserves CRLF in parsed parameter values

Summary Rack::Multipart::Parser unfolds folded multipart part headers incorrectly. When a multipart header contains an obs-fold sequence, Rack preserves the embedded CRLF in parsed parameter values such as filename or name instead of removing the folded line break during unfolding. As a result,...

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...

Nhost Leaks Refresh Tokens via URL Query Parameter in OAuth Provider Callback

Refresh Token Leaked via URL Query Parameter in OAuth Provider Callback Summary The auth service's OAuth provider callback flow places the refresh token directly into the redirect URL as a query parameter. Refresh tokens in URLs are logged in browser history, server access logs, HTTP Referer...

CVE-2025-66485

IBM Aspera Shares 1.9.9 through 1.11.0 is vulnerable to HTTP header injection, caused by improper validation of input by the HOST headers. This could allow an attacker to conduct various attacks against the vulnerable system, including cross-site scripting, cache poisoning or session hijacking...

CVE-2026-34520

A flaw was found in AIOHTTP, an asynchronous HTTP client/server framework for Python. The default C parser incorrectly processed null bytes and control characters present in HTTP response headers. This vulnerability could allow a remote attacker to inject malicious data into these headers,...

CVE-2026-22815

A flaw was found in AIOHTTP, an asynchronous HTTP client/server framework for Python. Insufficient restrictions in header and trailer handling could allow a remote attacker to cause uncapped memory usage. This can lead to a Denial of Service DoS condition, making the affected web server...

GHSA-HPM8-9QX6-JVWV Parser Server's streaming file download bypasses afterFind file trigger authorization

Impact File downloads via HTTP Range requests bypass the afterFindParse.File trigger and its validators on storage adapters that support streaming e.g. the default GridFS adapter. This allows access to files that should be protected by afterFind trigger authorization logic or built-in validators...
