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...

Name of the Vulnerable Software and Affected Versions Rack versions 3.2.0 through 3.2.5 Description Rack’s Rack::Multipart::Parser incorrectly unfolds folded multipart part headers. When a multipart header contains an obs-fold sequence, Rack preserves the embedded CRLF in parsed parameter values...

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,...

CVE-2026-5315

A vulnerability was determined in Nothings stb up to 1.26. The affected element is the function stbttbufget8 in the library stbtruetype.h of the component TTF File Handler. Executing a manipulation can lead to out-of-bounds read. The attack can be executed remotely. The exploit has been publicly...

GHSA-X2W3-23JR-HRPF ewe Has Improper Neutralization of CRLF Sequences in HTTP Headers (HTTP Request/Response Splitting)

Summary The encodeheaders function in src/ewe/internal/encoder.gleam directly interpolates response header keys and values into raw HTTP bytes without validating or stripping CRLF \r\n sequences. An application that passes user-controlled data into response headers e.g., setting a Location redire...

GHSA-63HF-3VF5-4WQF AIOHTTP's C parser (llhttp) accepts null bytes and control characters in response header values - header injection/security bypass

Summary The C parser the default for most installs accepted null bytes and control characters in request headers. Impact An attacker could send header values that are interpreted differently than expected due to the presence of control characters. For example, request.url.origin may return a...

HTTP Response Splitting

Overview Affected versions of this package are vulnerable to HTTP Response Splitting in the llhttp component. An attacker can manipulate HTTP response headers by injecting null bytes or control characters, causing headers to be interpreted differently by various components, which may lead to...

AIOHTTP has HTTP response splitting via \r in reason phrase

Summary An attacker who controls the reason parameter when creating a Response may be able to inject extra headers or similar exploits. Impact In the unlikely situation that an application allows untrusted data to be used in the response's reason parameter, then an attacker could manipulate the...

HTTP Response Splitting

Overview Affected versions of this package are vulnerable to HTTP Response Splitting via the reason parameter in the HTTP response creation process. An attacker can inject unauthorized headers or manipulate the HTTP response by supplying specially crafted input containing carriage return...

HTTP Response Splitting

Overview Affected versions of this package are vulnerable to HTTP Response Splitting in the construction of multipart request headers when untrusted input is used for the contenttype parameter. An attacker can inject arbitrary headers or manipulate HTTP requests by supplying specially crafted...
