gRPC-Go: xDS RBAC HTTP Filter bypass via mixed-case Header Matching and gRFC A41 validation evasion

Summary A vulnerability in the xDS RBAC HTTP filter implementation in grpc-go allows remote attackers to bypass authorization policies specifically DENY rules by using mixed-case or canonical-case header matchers e.g., X-Role instead of x-role. Additionally, the safety guards introduced by gRFC A...

HTTPX2: Streaming response decompression does not bound peak memory (decompression amplification)

Summary When decoding a compressed response body gzip, deflate, br, or zstd, HTTPX2 fully decompressed each network read before yielding content to the application. A small compressed input could therefore cause a large intermediate memory allocation, even when the application streamed the respon...

Vitest: Path Traversal / Arbitrary File Read via @vitest/mocker Redirect Mock

Summary @vitest/mocker registers a redirect mock's target path without validating it against the dev server's file-serving allowlist. An attacker who can reach the dev server's WebSocket can register a redirect mock pointing outside the project root; when the mocked module is requested, the...

HTTPX2: Conflicting Content-Length and Transfer-Encoding headers can be auto-generated

Summary HTTPX2 can automatically add a Content-Length header to a request that already contains a caller-supplied Transfer-Encoding header. The resulting HTTP/1.1 request contains both framing headers, which can create an ambiguous message boundary and enable request smuggling or connection...

HTTPX2: Multipart part header injection via unvalidated file Content-Type and custom headers

Summary HTTPX2 serializes the per-file Content-Type and custom headers supplied through the files= tuple API directly into the multipart/form-data body without validating custom header names or values. An attacker who can influence upload metadata passed to HTTPX2 can use CR or LF characters to...

HTTPX2: Quadratic SSE line buffering can cause CPU denial of service

Summary HTTPX2's Server-Sent Events SSE parser repeatedly copied and rescanned buffered text when a server split one unterminated line across many response chunks. The total work grows quadratically with the length of the line. An attacker-controlled or compromised SSE endpoint can exploit this...

HTTPX2: Secure WebSocket traffic sent without TLS through SOCKS proxies

Summary httpcore2 does not start TLS for wss:// connections routed through a SOCKS5 proxy. The WebSocket opening handshake and all subsequent frames are sent in plaintext through the proxy path, despite the caller selecting the secure wss scheme. The transport flaw affects httpcore2 releases befo...

LiquidJS: Uncontrolled Resource Consumption in `join` filter allows template authors to bypass `memoryLimit` and crash the process

Summary The join filter src/filters/array.ts:8-13 charges memoryLimit by array element count, not by the string length it produces, letting a template bypass a configured memoryLimit and allocate strings far past budget — bounded only by V8/process limits, not by memoryLimit. Details js //...

Prowler: Stored XSS in HTML reports through unescaped cloud resource tags

Summary Prowler's HTML output formatter inserts finding.resourcetags into the generated report without HTML escaping. A cloud principal who can create or edit a resource tag in an account that is later scanned can store HTML or JavaScript in that tag. When another user opens the generated Prowler...

node-csv: Prototype replacement still reachable via columns path

Impact With columns: true and groupcolumnsbyname: true, a duplicated proto header causes the duplicate-column branch to assign an array to obj'proto', invoking the proto setter and replacing the parsed record object's prototype with attacker-controlled data. Fixed in 7.0.2 Object.hasOwn duplicate...

SWC HTML minifier may allow script element breakout when minifying embedded JSON

Impact @swc/html minifies JSON contained in script elements such as application/json and application/ld+json by parsing and serializing the JSON value. Before the patched versions, JSON serialization could convert escaped less-than signs such as \u003C into literal sequence, the generated HTML...

It was introduced on the development branch by commit acfc02ee8 "Improve database field visibility across views", 11020 and is live on v3.7.4-alpha.1, so it will ship in v3.7.4 unless gated first. No released stable...

NLTK: Corpus Reader Sandbox Bypass

Summary NLTK corpus-reader constructors can still reach outside-root file and database reads before the nltk.pathsec sandbox boundary is enforced. The PoC shows the safe path blocked by pathsec.open, then LinThesaurusCorpusReader and PanLexLiteCorpusReader succeeding in the same process. Affected...

NLTK: Corpus readers follow symlinks outside trusted roots despite pathsec enforcement

Summary Several corpus readers still step outside NLTK's symlink-aware trusted-root model. They derive in-root paths from trusted corpus state, convert those paths back into plain strings, and reopen them with built-in open rather than nltk.pathsec.open. Details - Vulnerability type: Path travers...

NLTK: Allowlisted pickle loaders still permit code execution in current source

Summary The current source tree still allows arbitrary code execution during supposedly safer allowlisted pickle loading. The allowlist trusts whole module namespaces instead of exact safe globals, so crafted pickles can invoke dangerous in-namespace callables through pickle REDUCE. Details -...

NLTK: Entity-expansion DoS (billion laughs) via remaining raw ElementTree parses

Several XML parsing sites in NLTK still used xml.etree.ElementTree directly, which honours declarations in a document's internal DTD subset. A crafted document a few hundred bytes long can expand to megabytes in memory each nesting level multiplies by ten, a denial-of-service. Affected call sites...

NLTK: pathsec SSRF protection can be bypassed when a proxy is configured

Summary Current NLTK source reopens SSRF in proxied environments. pathsec.urlopen validates the requested hostname locally, but once proxy inheritance is enabled the real fetch is performed by the proxy rather than by the validated direct-connect socket path. Details - Vulnerability type:...
