| 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 |
| libheif is an HEIF and AVIF file format decoder and encoder. Prior to version 1.21.0, a crafted HEIF that exercises the overlay image item path triggers a heap buffer over-read in `HeifPixelImage::overlay()`. The function computes a negative row length (likely from an unclipped overlay rectangle or invalid offsets), which then underflows when converted to `size_t` and is passed to `memcpy`, causing a very large read past the end of the source plane and a crash. Version 1.21.0 contains a patch. As a workaround, avoid decoding images using `iovl` overlay boxes. |

| The Advanced Ads plugin for WordPress is vulnerable to Remote Code Execution in versions up to, and including, 2.0.14 via the 'change-ad__content' shortcode parameter. This allows authenticated attackers with editor-level permissions or above, to execute code on the server. |
| A vulnerability in the SSH server of TP-Link TL-WR820N v2.80 allows the use of a weak cryptographic algorithm, enabling an adjacent attacker to intercept and decrypt SSH traffic. Exploitation may expose sensitive information and compromise confidentiality. |
| The PixelYourSite plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 11.1.5 through publicly exposed log files. This makes it possible for unauthenticated attackers to view potentially sensitive information contained in the exposed log files, when the "Meta API logs" setting is enabled (disabled by default). The vulnerability was partially patched in version 11.1.5 and fully patched in version 11.1.5.1. |
