Practical Security Guides For Your Team
Clear, non-alarmist guidance for real web vulnerabilities so your team can prioritize fixes confidently.
Outdated HTTP Library Can Be Used to Crash Your Application
mediumYour application uses an outdated version of Axios, a popular tool for making web requests. A known flaw in this version means that a malicious server — or an unexpectedly large response — can keep sending data even after your app has told it to stop, eventually overwhelming your server and causing it to crash or become unresponsive. The fix is a straightforward library upgrade.
JavaScript Utility Library Can Be Crashed by Malicious Input (CVE-2026-27601)
highYour application uses a JavaScript helper library called Underscore.js that has a flaw in two of its functions. Under specific conditions, an attacker could send specially crafted deeply-nested data to your server, causing it to crash and become temporarily unavailable. Think of it like sending a letter with 4,500 envelopes nested inside each other — the library tries to open every one and runs out of room.
Outdated HTTP Library Can Be Used to Knock Your App Offline
highYour application uses an old version of Axios (v0.12.0), a popular tool that helps your software communicate with other services over the internet. This version has a known flaw that lets anyone send a specially crafted request to slow your server to a crawl — potentially making your app unavailable to real users. Upgrading to a newer version takes a developer less than an hour and fully resolves the issue.
Axios Library Flaw Lets Attackers Crash Your Backend Service (CVE-2026-25639)
highYour application uses a popular networking library called Axios to make web requests. A flaw in this library means that if your app accepts data from users, parses it as JSON, and passes it into Axios, an attacker can send a single specially crafted request that instantly crashes your server. Think of it like a specific combination lock that, when entered, causes the door to fall off its hinges rather than just staying locked.
Next.js Server Crash Vulnerability via Oversized Requests (CVE-2025-59472)
highA flaw in a specific Next.js feature called Partial Prerendering (PPR) allows anyone on the internet to crash your web server by sending a specially crafted request — no login required. This only affects self-hosted Next.js applications running in a specific 'minimal mode' configuration with PPR turned on. If your app is hosted on Vercel's platform, you are not affected.
Outdated Date Library Can Be Used to Slow Down or Crash Your App
mediumYour application is using an old version of Moment.js, a popular tool for handling dates and times. This version has a known weakness: if someone sends it a very long, specially crafted piece of text, it can cause your app to freeze or become unresponsive while it tries to process it. Think of it like a lock that jams when you insert a bent key — the door stops working for everyone until the jam clears.
Outdated Date Library Can Be Used to Slow Down or Crash Your Application
highYour application uses an outdated version of Moment.js — a popular tool developers use to handle dates and times. This version has a known flaw where sending it an unusually long piece of text can cause it to get stuck processing, slowing your app to a crawl or making it temporarily unavailable to users. This only matters if your app accepts date input directly from users or external sources.
Outdated Lodash Library Allows Attackers to Run Malicious Code on Your Server
highYour application uses an old version of Lodash (3.10.1), a popular JavaScript helper library. This version has a known security flaw that could allow an attacker with access to your system to run their own commands on your server. Upgrading to the latest version closes this gap completely.
Outdated Lodash Library Allows Application Logic Tampering
highYour application uses a very old version of Lodash (3.10.1), a popular JavaScript utility library, that has a known security flaw. An attacker who can send crafted data to your application could manipulate how JavaScript objects behave globally — think of it like someone secretly changing the rules of the game for every player at once. Upgrading to the latest version of Lodash closes this gap immediately.
Outdated JavaScript Utility Library Allows Application Disruption (CVE-2018-16487)
highYour application is using a very old version of lodash (3.10.1), a popular JavaScript helper library, that contains a known security flaw. An attacker who can send crafted data to your application could use this flaw to disrupt your service or, in some cases, interfere with how your application behaves. The fix is a straightforward library upgrade.
Outdated JavaScript Utility Library Allows Application Behavior Tampering
mediumYour application uses an old version of a popular JavaScript helper library called Lodash (version 3.10.1) that contains a known security flaw. An attacker who can send crafted data to your app could manipulate how it processes objects internally, potentially disrupting its behavior. Upgrading to the latest version of Lodash takes a developer under an hour and fully resolves the issue.
Outdated Date Library Allows Attackers to Tamper with Server Files
highYour application uses an outdated version of Moment.js — a popular tool for handling dates and times — that contains a known security flaw. If any part of your app lets users choose a language or locale (e.g., 'English', 'French'), an attacker could craft a malicious input to access or manipulate files on your server that they shouldn't be able to touch. This only affects server-side usage, not purely browser-based code.
