  - Improper Input Validation vulnerability in qs (parse modules) allows HTTP DoS.This issue affects qs: <
    6.14.1. SummaryThe arrayLimit option in qs does not enforce limits for bracket notation (a[]=1&a[]=2),
    allowing attackers to cause denial-of-service via memory exhaustion. Applications using arrayLimit for DoS
    protection are vulnerable. DetailsThe arrayLimit option only checks limits for indexed notation
    (a[0]=1&a[1]=2) but completely bypasses it for bracket notation (a[]=1&a[]=2). Vulnerable code
    (lib/parse.js:159-162): if (root === '[]' && options.parseArrays) { obj = utils.combine([], leaf); // No
    arrayLimit check } Working code (lib/parse.js:175): else if (index <= options.arrayLimit) { // Limit
    checked here obj = []; obj[index] = leaf; } The bracket notation handler at line 159 uses
    utils.combine([], leaf) without validating against options.arrayLimit, while indexed notation at line 175
    checks index <= options.arrayLimit before creating arrays. PoCTest 1 - Basic bypass: npm install qs const
    qs = require('qs'); const result = qs.parse('a[]=1&a[]=2&a[]=3&a[]=4&a[]=5&a[]=6', { arrayLimit: 5 });
    console.log(result.a.length); // Output: 6 (should be max 5) Test 2 - DoS demonstration: const qs =
    require('qs'); const attack = 'a[]=' + Array(10000).fill('x').join('&a[]='); const result =
    qs.parse(attack, { arrayLimit: 100 }); console.log(result.a.length); // Output: 10000 (should be max 100)
    Configuration: * arrayLimit: 5 (test 1) or arrayLimit: 100 (test 2) * Use bracket notation: a[]=value (not
    indexed a[0]=value) ImpactDenial of Service via memory exhaustion. Affects applications using qs.parse()
    with user-controlled input and arrayLimit for protection. Attack scenario: * Attacker sends HTTP request:
    GET /api/search?filters[]=x&filters[]=x&...&filters[]=x (100,000+ times) * Application parses with
    qs.parse(query, { arrayLimit: 100 }) * qs ignores limit, parses all 100,000 elements into array * Server
    memory exhausted  application crashes or becomes unresponsive * Service unavailable for all users Real-
    world impact: * Single malicious request can crash server * No authentication required * Easy to automate
    and scale * Affects any endpoint parsing query strings with bracket notation (CVE-2025-15284)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
