CVE-2023-45133

Vulnerable Library - traverse-7.16.3.tgz

The Babel Traverse module maintains the overall tree state, and is responsible for replacing, removing, and adding nodes

Library home page: https://registry.npmjs.org/@⁠babel/traverse/-/traverse-7.16.3.tgz

Found in base branch: main

Vulnerability Details

Babel is a compiler for writingJavaScript. In "@⁠babel/traverse" prior to versions 7.23.2 and 8.0.0-alpha.4 and all versions of "babel-traverse", using Babel to compile code that was specifically crafted by an attacker can lead to arbitrary code execution during compilation, when using plugins that rely on the "path.evaluate()"or "path.evaluateTruthy()" internal Babel methods. Known affected plugins are "@⁠babel/plugin-transform-runtime"; "@⁠babel/preset-env" when using its "useBuiltIns" option; and any "polyfill provider" plugin that depends on "@⁠babel/helper-define-polyfill-provider", such as "babel-plugin-polyfill-corejs3", "babel-plugin-polyfill-corejs2", "babel-plugin-polyfill-es-shims", "babel-plugin-polyfill-regenerator". No other plugins under the "@⁠babel/" namespace are impacted, but third-party plugins might be. Users that only compile trusted code are not impacted. The vulnerability has been fixed in "@⁠babel/traverse@7.23.2" and "@⁠babel/traverse@8.0.0-alpha.4". Those who cannot upgrade "@⁠babel/traverse" and are using one of the affected packages mentioned above should upgrade them to their latest version to avoid triggering the vulnerable code path in affected "@⁠babel/traverse" versions: "@⁠babel/plugin-transform-runtime" v7.23.2, "@⁠babel/preset-env" v7.23.2, "@⁠babel/helper-define-polyfill-provider" v0.4.3, "babel-plugin-polyfill-corejs2" v0.4.6, "babel-plugin-polyfill-corejs3" v0.8.5, "babel-plugin-polyfill-es-shims" v0.10.0, "babel-plugin-polyfill-regenerator" v0.5.3.

Vulnerability Details

ws is an open source WebSocket client and server for Node.js. All versions from 1.1.0 up to (but not including) 5.2.5, from 6.0.0 up to 6.2.4, from 7.0.0 up to 7.5.11, and from 8.0.0 up to 8.21.0 are affected by a memory exhaustion DoS vulnerability. A peer can send a high volume of exceptionally small fragments and data chunks, with modest network traffic, to force the remote peer into allocating and holding structural wrappers that consume far more memory than the default documented message-size limit, leading to process termination due to OOM. This issue has been fixed in versions 5.2.5, 6.2.4, 7.5.11, and 8.21.0.

          • jsdom-16.7.0.tgz
            • form-data-3.0.1.tgz (Vulnerable Library)

Found in base branch: main

Vulnerability Details

form-data is a library for creating readable multipart/form-data streams. In versions through 4.0.5, the "field" argument to "FormData#append" and the "filename" option are concatenated verbatim into the "Content-Disposition" header without escaping carriage return (CR), line feed (LF), or double-quote (") characters. An application that passes attacker-controlled data as a field name or filename (for example, an API gateway that turns JSON object keys into multipart field names) allows the attacker to terminate the header line and inject additional headers, or to smuggle entire additional multipart parts, into the request the application forwards to a backend. This can let the attacker add or override form fields (e.g. set "is_admin=true") seen by the downstream parser. This is an instance of CWE-93 (CRLF injection). The fix escapes CR, LF, and """ as "%0D", "%0A", and "%22" in field names and filenames, matching the serialization browsers use per the WHATWG HTML multipart/form-data encoding algorithm. Exploitation requires the consuming application to use untrusted input as a field name or filename; applications that use only fixed/trusted field names are not affected. Fixed in 2.5.6, 3.0.5, and 4.0.6.

Vulnerability Details

ws is an open source WebSocket client and server for Node.js. A request with a number of headers exceeding theserver.maxHeadersCount threshold could be used to crash a ws server. The vulnerability was fixed in ws@8.17.1 (e55e510) and backported to ws@7.5.10 (22c2876), ws@6.2.3 (eeb76d3), and ws@5.2.4 (4abd8f6). In vulnerable versions of ws, the issue can be mitigated in the following ways: 1. Reduce the maximum allowed length of the request headers using the --max-http-header-size=size and/or the maxHeaderSize options so that no more headers than the server.maxHeadersCount limit can be sent. 2. Set server.maxHeadersCount to 0 so that no limit is applied.

Found in base branch: main

Vulnerability Details

Babel is a compiler for writing next generation JavaScript. When using versions of Babel prior to 7.26.10 and 8.0.0-alpha.17 to compile regular expression named capturing groups, Babel will generate a polyfill for the ".replace" method that has quadratic complexity on some specific replacement pattern strings (i.e. the second argument passed to ".replace"). Generated code is vulnerable if all the following conditions are true: Using Babel to compile regular expression named capturing groups, using the ".replace" method on a regular expression that contains named capturing groups, and the code using untrusted strings as the second argument of ".replace". This problem has been fixed in "@⁠babel/helpers" and "@⁠babel/runtime" 7.26.10 and 8.0.0-alpha.17. It's likely that individual users do not directly depend on "@⁠babel/helpers", and instead depend on "@⁠babel/core" (which itself depends on "@⁠babel/helpers"). Upgrading to "@⁠babel/core" 7.26.10 is not required, but it guarantees use of a new enough "@⁠babel/helpers" version. Note that just updating Babel dependencies is not enough; one will also need to re-compile the code. No known workarounds are available.

Vulnerability Details

js-yaml is a JavaScript YAML parser and dumper. Prior to 4.2.0 and 3.15.0, a crafted YAML document can trigger algorithmic CPU exhaustion in js-yaml merge-key processing (<<) by repeating the same alias many times in a merge sequence. This causes quadratic parse-time behavior relative to input size and can block a Node.js worker/event loop for seconds with a relatively small payload (tens of KB), resulting in denial of service. The issue is in merge handling inside lib/loader.js. This vulnerability is fixed in 4.2.0 and 3.15.0.

Vulnerability Details

js-yaml is a JavaScript YAML parser and dumper. In js-yaml before 4.1.1 and 3.14.2, it's possible for an attacker to modify the prototype of the result of a parsed yaml document via prototype pollution ("proto"). All users who parse untrusted yaml documents may be impacted. The problem is patched in js-yaml 4.1.1 and 3.14.2. Users can protect against this kind of attack on the server by using "node --disable-proto=delete" or "deno" (in Deno, pollution protection is on by default).

Vulnerability Details

Versions of the package @⁠tootallnate/once before 3.0.1 are vulnerable to Incorrect Control Flow Scoping in promise resolving when AbortSignal option is used. The Promise remains in a permanently pending state after the signal is aborted, causing any await or .then() usage to hang indefinitely. This can cause a control-flow leak that can lead to stalled requests, blocked workers, or degraded application availability.

Vulnerability Details

Babel is a compiler for writing next generation JavaScript. Prior to 8.0.0-rc.6 and 7.29.6, @⁠babel/core affected by an arbitrary file read via a sourceMappingURL comment. Using @⁠babel/core to compile maliciously crafted code can allow an attacker to read any source map from the system that is running Babel, if the attacker controls the input source code, can read the output source code, and knows the path of the source map file that they want to read. This vulnerability is fixed in 8.0.0-rc.6 and 7.29.6.
