All the vulnerabilities related to the version 0.3.3 of the package
ejs lacks certain pollution protection
The ejs (aka Embedded JavaScript templates) package before 3.1.10 for Node.js lacks certain pollution protection.
ejs template injection vulnerability
The ejs (aka Embedded JavaScript templates) package 3.1.6 for Node.js allows server-side template injection in settings[view options][outputFunctionName]. This is parsed as an internal option, and overwrites the outputFunctionName option with an arbitrary OS command (which is executed upon template compilation).
Pug allows JavaScript code execution if an application accepts untrusted input
Pug through 3.0.2 allows JavaScript code execution if an application accepts untrusted input for the name option of the compileClient
, compileFileClient
, or compileClientWithDependenciesTracked
function. NOTE: these functions are for compiling Pug templates into JavaScript, and there would typically be no reason to allow untrusted callers.
Remote code execution via the pretty
option.
If a remote attacker was able to control the pretty
option of the pug compiler, e.g. if you spread a user provided object such as the query parameters of a request into the pug template inputs, it was possible for them to achieve remote code execution on the node.js backend.
Upgrade to pug@3.0.1
or pug-code-gen@3.0.2
or pug-code-gen@2.0.3
, which correctly sanitise the parameter.
If there is no way for un-trusted input to be passed to pug as the pretty
option, e.g. if you compile templates in advance before applying user input to them, you do not need to upgrade.

Path Traversal in serve
Versions of serve
prior to 10.1.2 are vulnerable to Path Traversal. Explicitly ignored folders can be accessed through relative paths, which allows attackers to access hidden folders and files.
Upgrade to version 10.1.2 or later.
Information Exposure on Case Insensitive File Systems in serve
Versions of serve
before 7.0.0 are vulnerable to information exposure, bypassing the ignore security control, but only on case insensitive file systems.
Update to version 7.0.0 or later.
Cross-Site Scripting in serve
Versions of serve
prior to 10.0.2 are vulnerable to Cross-Site Scripting (XSS). The package fails to sanitize filenames, allowing attackers to execute arbitrary JavaScript in the victim's browser through files with names containing malicious code.
Upgrade to version 10.0.2 or later.
Path Traversal in serve
Versions of serve
prior to 7.0.1 are vulnerable to Path Traversal. Explicitly ignored folders can be accessed through if the path contains a /./
, which allows attackers to access hidden folders and files.
Upgrade to version 7.0.1 or later.
Directory Traversal in serve
Versions of serve
before 7.1.3 are vulnerable to Directory Traversal. File paths are not sanitized leading to unauthorized access of system files.
Upgrade to version 7.1.3 or later
Cross-Site Scripting in serve
Versions of serve
prior to 10.0.2 are vulnerable to Cross-Site Scripting (XSS). The package does not encode output, allowing attackers to execute arbitrary JavaScript in the victim's browser if user-supplied input is rendered.
Upgrade to version 10.0.2 or later.
ip SSRF improper categorization in isPublic
The ip package through 2.0.1 for Node.js might allow SSRF because some IP addresses (such as 127.1, 01200034567, 012.1.2.3, 000:0:0000::01, and ::fFFf:127.0.0.1) are improperly categorized as globally routable via isPublic. NOTE: this issue exists because of an incomplete fix for CVE-2023-42282.
NPM IP package incorrectly identifies some private IP addresses as public
The isPublic()
function in the NPM package ip
doesn't correctly identify certain private IP addresses in uncommon formats such as 0x7F.1
as private. Instead, it reports them as public by returning true
. This can lead to security issues such as Server-Side Request Forgery (SSRF) if isPublic()
is used to protect sensitive code paths when passed user input. Versions 1.1.9 and 2.0.1 fix the issue.
send vulnerable to template injection that can lead to XSS
passing untrusted user input - even after sanitizing it - to SendStream.redirect()
may execute untrusted code
this issue is patched in send 0.19.0
users are encouraged to upgrade to the patched version of express, but otherwise can workaround this issue by making sure any untrusted inputs are safe, ideally by validating them against an explicit allowlist
successful exploitation of this vector requires the following:
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.
liquidjs may leak properties of a prototype
The package liquidjs before 10.0.0 is vulnerable to Information Exposure when ownPropertyOnly
parameter is set to False
, which results in leaking properties of a prototype. Workaround For versions 9.34.0 and higher, an option to disable this functionality is provided.
Prototype Pollution in lodash
Versions of lodash prior to 4.17.19 are vulnerable to Prototype Pollution. The functions pick
, set
, setWith
, update
, updateWith
, and zipObjectDeep
allow a malicious user to modify the prototype of Object if the property identifiers are user-supplied. Being affected by this issue requires manipulating objects based on user-provided property values or arrays.
This vulnerability causes the addition or modification of an existing property that will exist on all objects and may lead to Denial of Service or Code Execution under specific circumstances.
Uncontrolled Resource Consumption in markdown-it
Special patterns with length > 50K chars can slow down parser significantly.
const md = require('markdown-it')();
md.render(`x ${' '.repeat(150000)} x \nx`);
Upgrade to v12.3.2+
No.
Fix + test sample: https://github.com/markdown-it/markdown-it/commit/ffc49ab46b5b751cd2be0aabb146f2ef84986101
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.
