Babel vulnerable to arbitrary code execution when compiling specifically crafted malicious code
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@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
.
Babel 6 does not receive security fixes anymore (see Babel's security policy), hence there is no patch planned for babel-traverse@6
.
@babel/traverse
to v7.23.2 or higher. You can do this by deleting it from your package manager's lockfile and re-installing the dependencies. @babel/core
>=7.23.2 will automatically pull in a non-vulnerable version.@babel/traverse
and are using one of the affected packages mentioned above, 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
v0.4.3babel-plugin-polyfill-corejs2
v0.4.6babel-plugin-polyfill-corejs3
v0.8.5babel-plugin-polyfill-es-shims
v0.10.0babel-plugin-polyfill-regenerator
v0.5.3Prototype Pollution in Ajv
An issue was discovered in ajv.validate() in Ajv (aka Another JSON Schema Validator) 6.12.2. A carefully crafted JSON schema could be provided that allows execution of other code by prototype pollution. (While untrusted schemas are recommended against, the worst case of an untrusted schema should be a denial of service, not execution of code.)
Improper Privilege Management in shelljs
shelljs is vulnerable to Improper Privilege Management
Improper Privilege Management in shelljs
Output from the synchronous version of shell.exec()
may be visible to other users on the same system. You may be affected if you execute shell.exec()
in multi-user Mac, Linux, or WSL environments, or if you execute shell.exec()
as the root user.
Other shelljs functions (including the asynchronous version of shell.exec()
) are not impacted.
Patched in shelljs 0.8.5
Recommended action is to upgrade to 0.8.5.

If you have any questions or comments about this advisory:
Regular Expression Denial of Service (ReDoS)
A vulnerability was found in diff before v3.5.0, the affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) attacks.
Growl before 1.10.0 vulnerable to Command Injection
Affected versions of growl
do not properly sanitize input prior to passing it into a shell command, allowing for arbitrary command execution.
Update to version 1.10.0 or later.
Denial of Service in mem
Versions of mem
prior to 4.0.0 are vulnerable to Denial of Service (DoS). The package fails to remove old values from the cache even after a value passes its maxAge
property. This may allow attackers to exhaust the system's memory if they are able to abuse the application logging.
Upgrade to version 4.0.0 or later.
Regular Expression Denial of Service (ReDoS) in micromatch
The NPM package micromatch
prior to version 4.0.8 is vulnerable to Regular Expression Denial of Service (ReDoS). The vulnerability occurs in micromatch.braces()
in index.js
because the pattern .*
will greedily match anything. By passing a malicious payload, the pattern matching will keep backtracking to the input while it doesn't find the closing bracket. As the input size increases, the consumption time will also increase until it causes the application to hang or slow down. There was a merged fix but further testing shows the issue persisted prior to https://github.com/micromatch/micromatch/pull/266. This issue should be mitigated by using a safe pattern that won't start backtracking the regular expression due to greedy matching.
Uncontrolled resource consumption in braces
The NPM package braces
fails to limit the number of characters it can handle, which could lead to Memory Exhaustion. In lib/parse.js,
if a malicious user sends "imbalanced braces" as input, the parsing will enter a loop, which will cause the program to start allocating heap memory without freeing it at any moment of the loop. Eventually, the JavaScript heap limit is reached, and the program will crash.
yargs-parser Vulnerable to Prototype Pollution
Affected versions of yargs-parser
are vulnerable to prototype pollution. Arguments are not properly sanitized, allowing an attacker to modify the prototype of Object
, causing the addition or modification of an existing property that will exist on all objects.
Parsing the argument --foo.__proto__.bar baz'
adds a bar
property with value baz
to all objects. This is only exploitable if attackers have control over the arguments being passed to yargs-parser
.
Upgrade to versions 13.1.2, 15.0.1, 18.1.1 or later.
Regular Expression Denial of Service (ReDoS) in cross-spawn
Versions of the package cross-spawn before 7.0.5 are vulnerable to Regular Expression Denial of Service (ReDoS) due to improper input sanitization. An attacker can increase the CPU usage and crash the program by crafting a very large and well crafted string.
