Quarkus: Authentication/Authorization Bypass via Advanced Path Normalization Vulnerabilities

Quarkus HTTP path-based authorization policies can be bypassed using encoded semicolons %3B to smuggle matrix parameters past the security layer, and using encoded slashes %2F or backslashes %5C to access protected static resources. This is a distinct issue from CVE-2026-39852, which addressed on...

CVE-2026-44974

CVE-2026-44974 affects the @hapi/content header parser. Before v6.0.2, Content.disposition() kept the last value for duplicate parameters while Content.type() kept the first for duplicate charset/boundary parameters, creating a parameter-smuggling primitive when duplicates are resolved inconsiste...

PYSEC-2026-3037 python-multipart: Semicolon treated as querystring field separator enables parameter smuggling

Summary QuerystringParser treated ; as a field separator in application/x-www-form-urlencoded bodies, in addition to &. The WHATWG URL standard, modern browsers, and Python's urllib.parse since the CVE-2021-23336 fix treat only & as a separator. This creates a parser differential: the same bytes...

CVE-2026-53751

DataEase is an open source data visualization and analysis tool. Prior to 2.10.24, the H2 database JDBC URL validation logic can be bypassed with special Unicode characters whose case-conversion behavior differs between DataEase validation and H2 parsing, allowing attackers to smuggle dangerous...

CVE-2026-53751 DataEase: H2 JDBC URL Filter Bypass Leads to Remote Code Execution (RCE)

DataEase is an open source data visualization and analysis tool. Prior to 2.10.24, the H2 database JDBC URL validation logic can be bypassed with special Unicode characters whose case-conversion behavior differs between DataEase validation and H2 parsing, allowing attackers to smuggle dangerous...

CVE-2026-53537 Python-Multipart: Content-Disposition parameter smuggling via RFC 2231/5987 extended parameters

Python-Multipart is a streaming multipart parser for Python. Prior to 0.0.30, parseoptionsheader parsed Content-Disposition and Content-Type headers with email.message.Message, which transparently applies RFC 2231/5987 decoding. The extended parameter syntax filename=charset'lang'value, name=...,...

CVE-2026-53538

CVE-2026-53538 affects python-multipart, a streaming multipart parser for Python. Prior to 0.0.30, the QuerystringParser treated ";" as a field separator in application/x-www-form-urlencoded bodies in addition to "&", creating a parsing differential against WHATWG/urllib.parse behavior that only ...

CVE-2026-49756

CVE-2026-49756 describes a CRLF injection in Req.Utils.encode_form_part/2 of the Elixir Req library. User-controlled name, filename, or content_type are interpolated into Content-Disposition and Content-Type without escaping, allowing CRLFs to terminate header lines and add smuggled parts. This e...

CVE-2026-49756 Multipart form-data header injection in Req via unescaped name/filename/content_type

Improper Neutralization of CRLF Sequences 'CRLF Injection' vulnerability in wojtekmach Req allows multipart parameter smuggling via attacker-influenced part metadata. Req.Utils.encodeformpart/2 in lib/req/utils.ex builds the per-part headers by interpolating the caller-supplied name, filename, an...

@hapi/content header parser has a parameter smuggling issue that allows upload-filter bypass via duplicate parameters

Impact The two parsers resolved duplicates inconsistently and silently: - Content.disposition retained the last occurrence of each parameter. - Content.type retained the first occurrence of charset and boundary. Either behavior creates a parameter-smuggling primitive when another component in the...

Ruby Rack 3.x < 3.1.21 / 3.2.x < 3.2.6 Multiple Vulnerabilities

The version of the Rack Ruby library installed on the remote host is 3.0.0.beta1 or later but prior to 3.1.21, or is 3.2.0 or later but prior to 3.2.6. It is, therefore, affected by multiple vulnerabilities: - Rack::Multipart::Parserhandlemimehead parses quoted multipart parameters using repeated...
