How to Fix CVE-2022-25901

To remediate this vulnerability, upgrade all affected Cookiejar dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

cookiejar fixed: 2.1.4 
npm install cookiejar@2.1.4
org.webjars.npm:cookiejar fixed: Latest secure release 
<dependency>
    <groupId>org.webjars.npm</groupId>
    <artifactId>cookiejar</artifactId>
    <version>Latest secure release</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls cookiejar

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-25901, inspect your project dependencies using npm:

npm ls cookiejar

Analyze the terminal output to locate any version of Cookiejar in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.1.4), your application is affected.

Note: The npm ls cookiejar command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1333: Inefficient Regular Expression Complexity, where the product uses a regular expression with a worst-case computational complexity that is inefficient and possibly exponential. In Cookiejar, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Versions of the package cookiejar before 2.1.4 are vulnerable to Regular Expression Denial of Service (ReDoS) via the `Cookie.parse` function and other aspects of the API, which use an insecure regular expression for parsing cookie values. Applications could be stalled for extended periods of time if untrusted input is passed to cookie values or attempted to parse from request headers. Proof of concept: ``` ts\nconst { CookieJar } = require("cookiejar"); const jar = new CookieJar(); const start = performance.now(); const attack = "a" + "t".repeat(50_000); jar.setCookie(attack); console.log(`CookieJar.setCookie(): ${performance.now() - start}ms`); ``` ``` CookieJar.setCookie(): 2963.214399999939ms ```
