CVE-2026-34827 Rack: Algorithmic-Complexity DoS in Rack::Multipart::Parser
Rack is a modular Ruby web server interface. From versions 3.0.0.beta1 to before 3.1.21, and 3.2.0 to before 3.2.6, Rack::Multipart::Parserhandlemimehead parses quoted multipart parameters such as Content-Disposition: form-data; name="..." using repeated Stringindex searches combined with...
CVE-2026-34827
Rack CVE-2026-34827 describes an algorithmic-DoS in Rack::Multipart::Parser#handle_mime_head where quoted multipart parameters are parsed with repeated String#index searches and slice! prefix deletion. Affected versions are 3.0.0.beta1 up to before 3.1.21, and 3.2.0 up to before 3.2.6. An unauthe...
CVE-2026-32145 Multipart form body parser bypasses body size limits in wisp
Allocation of Resources Without Limits or Throttling vulnerability in gleam-wisp wisp allows a denial of service via multipart form body parsing. The multipartbody function bypasses configured maxbodysize and maxfilessize limits. When a multipart boundary is not present in a chunk, the parser tak...
CVE-2026-5318
A flaw was found in LibRaw. A remote attacker could exploit this vulnerability by manipulating the 'bits' argument within the 'HuffTable::initval' function of the JPEG DHT Parser component. This manipulation leads to an out-of-bounds write, which can result in a Denial of Service DoS condition,...
CVE-2026-5236
A vulnerability was identified in Axiomatic Bento4 up to 1.6.0-641. Affected is the function AP4BitReader::SkipBits of the file Ap4Dac4Atom.cpp of the component DSI v1 Parser. Such manipulation of the argument npresentations leads to heap-based buffer overflow. The attack needs to be performed...
Out-of-bounds Write
Overview Affected versions of this package are vulnerable to Out-of-bounds Write in the initval function of the JPEG DHT Parser component when processing the bits argument. An attacker can cause a denial of service by supplying a specially crafted JPEG file that triggers an out-of-bounds write...
EUVD-2026-18116
A weakness has been identified in LibRaw up to 0.22.0. This impacts the function HuffTable::initval of the file src/decompressors/losslessjpeg.cpp of the component JPEG DHT Parser. This manipulation of the argument bits causes out-of-bounds write. It is possible to initiate the attack remotely. T...

CVE-2026-5318
LibRaw is affected up to 0.22.0. The vulnerability resides in HuffTable::initval (src/decompressors/losslessjpeg.cpp) where manipulation of bits[] can trigger an out-of-bounds write. An attacker could potentially exploit this remotely, and a public exploit has been made available. The fix is the ...

PT-2026-29923
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,...

PT-2026-29910
Summary Rack::Multipart::Parser only wraps the request body in a BoundedIO when CONTENT LENGTH is present. When a multipart/form-data request is sent without a Content-Length header, such as with HTTP chunked transfer encoding, multipart parsing continues until end-of-stream with no total size...
Rack 安全漏洞
Rack is a modular Ruby web server interface developed by the Rack open-source project. Versions of Rack prior to 2.2.23, 3.1.21, and 3.2.6 contained security vulnerabilities. These vulnerabilities stemmed from the use of greedy regular expressions by the multipart parser to extract boundary...

Summary Rack::Multipart::Parser extracts the boundary parameter from multipart/form-data using a greedy regular expression. When a Content-Type header contains multiple boundary parameters, Rack selects the last one rather than the first. In deployments where an upstream proxy, WAF, or intermedia...
Rack's greedy multipart boundary parsing can cause parser differentials and WAF bypass.
