Esdoc version 1.1.0 represents an incremental upgrade over version 1.0.4, offering improvements and updated dependencies that enhance its functionality as a JavaScript documentation generator. A key difference lies in the updated dependencies. Notably, cheerio jumps from version 0.22.0 to 1.0.0-rc.2, which likely brings performance improvements and updated DOM manipulation capabilities. Significant updates across fs-extra dependencies providing enhanced file system operations can also be found across the versions along with updates to babel packages. Conversely, version 1.0.4 relies on older versions of these fundamental tools.
For developers, this means version 1.1.0 potentially offers better support for modern JavaScript syntax and features, resulting in more accurate and comprehensive documentation. Furthermore, several development dependencies have been updated. This not only brings bug fixes and security improvements but also aligns the development environment with current best practices, potentially simplifying contributions or custom plugin development. Version 1.1.0 also includes new dev dependencies codecov for code coverage reporting. The newer esdoc iteration will provide a more robust and up-to-date documentation generation experience, streamlining the process and improving the resulting documentation quality.
All the vulnerabilities related to the version 1.1.0 of the package
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-regeneratorNo 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:

What kind of vulnerability is it?
Denial of service.
The regular expression inline.reflinkSearch may cause catastrophic backtracking against some strings.
PoC is the following.
import * as marked from 'marked';
console.log(marked.parse(`[x]: x
\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](\\[\\](`));
Who is impacted?
Anyone who runs untrusted markdown through marked and does not use a worker with a time limit.
Has the problem been patched?
Yes
What versions should users upgrade to?
4.0.10
Is there a way for users to fix or remediate the vulnerability without upgrading?
Do not run untrusted markdown through marked or run marked on a worker thread and set a reasonable time limit to prevent draining resources.
Are there any links users can visit to find out more?

Marked ReDoS due to email addresses being evaluated in quadratic time
Versions of marked from 0.3.14 until 0.6.2 are vulnerable to Regular Expression Denial of Service. Email addresses may be evaluated in quadratic time, allowing attackers to potentially crash the node process due to resource exhaustion.
Upgrade to version 0.6.2 or later.
Prototype Pollution in minimist
Affected versions of minimist 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 --__proto__.y=Polluted adds a y property with value Polluted to all objects. The argument --__proto__=Polluted raises and uncaught error and crashes the application.
This is exploitable if attackers have control over the arguments being passed to minimist.
Upgrade to versions 0.2.1, 1.2.3 or later.
Prototype Pollution in minimist
Minimist prior to 1.2.6 and 0.2.4 is vulnerable to Prototype Pollution via file index.js, function setKey() (lines 69-95).
TaffyDB can allow access to any data items in the DB
TaffyDB allows attackers to forge adding additional properties into user-input processed by taffy which can allow access to any data items in the DB. Taffy sets an internal index for each data item in its DB. However, it is found that the internal index can be forged by adding additional properties into user-input. If index is found in the query, TaffyDB will ignore other query conditions and directly return the indexed data item. Moreover, the internal index is in an easily-guessable format (e.g., T000002R000001). As such, attackers can use this vulnerability to access any data items in the DB. Note: taffy and its successor package taffydb are not maintained.
