🔥 Chrome RCE PoC: CVE-2026-6307 A working renderer RCE Proof of Concept for CVE-2026-6307 — a V8 type-confusion bug (JS-to-Wasm deoptimization) patched in Chrome 147.0.7727.101. ✅ Full primitives (addrof/fakeobj, out-of-cage, in-cage r/w) ✅ No-ASLR RCE that patches JIT code to pop xcalc ✅ Based on Nebula Security writeup ✅ Heavily improved with frontier LLMs + human direction (4-day experiment) This is renderer-only and still far from fully weaponized, but great for learning and research. 📥 PoC + scripts: https://github.com/0xsha/CVE-2026-6307 #Chrome #V8 #Exploit #CVE #SecurityResearch

💥TORLINK: A torrent finder that runs right from your terminal with zero setup and nothing to configure. One search checks a small curated list of sources at once. Pick what you want, and it downloads directly to your computer. GitHub: https://github.com/baairon/torlink

🔴 Another serious security vulnerability has been discovered in Redis 8.8.0, and no POC has been released yet for this bidirectional RCE found by v12sec.

🛡️ Bug Bounty Tip: Test IDOR + Web Cache Deception Together When hunting IDORs, always check for web cache deception on the same endpoints: 1. As User A, access a sensitive resource like /api/invoices/123 (also try appending .css or `.js`). 2. As User B, repeat the exact same URL with identical headers. 3. Only change the Cookie/Auth token. If User B receives User A's 200 OK response from cache → you've likely found a critical vulnerability! This combo can lead to account takeover-level impacts. #BugBounty #AppSec #WebSecurity #IDOR #Pentesting

🔍 Detailed Bug Bounty Tip: Publicly Exposed Firebase Config → Unauthorized Data Uploads Found a juicy misconfiguration during a recon phase! ### Vulnerability: Many web/mobile apps use Firebase Realtime Database (Google) and leave the configuration exposed in client-side JavaScript or source code. When the database security rules are not properly set (often left as default "true" for testing), anyone can read and write data without authentication. This leads to unauthorized data injection, tampering, or even full database takeover. ### How to Test: 1. Hunt for Firebase config in JS files, source code, or APK (look for firebaseConfig, apiKey, databaseURL, projectId etc.) 2. Identify the database URL (usually `https://<project-id>.firebaseio.com`) 3. Test write access with a simple PUT request ### Exploitation Command:

curl -X PUT "https://your-project-id.firebaseio.com/poc.json" \
     -d '{"POC": "Successful upload by Bug Hunter", "timestamp": "2026"}'

Replace your-project-id with the actual one. If successful, you'll be able to inject arbitrary data into the database. Proof of Concept Result: The database accepted the PUT request and stored the attacker-controlled JSON data. ### Impact: - Data pollution / poisoning - Injecting malicious content (e.g., XSS payloads, fake user data, phishing links) - Potential account takeover or business logic abuse depending on how the app uses the data - In severe cases → complete database compromise ### How to Report & Fix (for devs): - Set proper Firebase Realtime Database Security Rules (deny read/write by default) - Use Firebase Authentication - Avoid exposing sensitive config in client-side code when possible - Use Firestore with stricter rules instead (if applicable) Pro Tip: Always check .js files and network tab for firebaseio.com during recon. Many programs pay well for this! #BugBounty #BugBountyTips #Firebase #WebAppSec #HackerOne #Bugcrowd #Pentesting #CyberSecurity

🚨 Bug Bounty Tip: Password Reset Race Condition Many applications generate a password reset token but fail to invalidate it when critical account details change. This can create a dangerous account takeover scenario. Test Flow: 1️⃣ Request a password reset for your account. 2️⃣ Do not use the reset link yet. 3️⃣ Log in normally using your current password. 4️⃣ Change your email address (or another identifier linked to password recovery). 5️⃣ Now open the old password reset link you received before the email change. 💥 Potential Finding: If the old reset token still resets the password after the email change, the application isn't invalidating previously issued reset tokens. An attacker with access to an older reset email could still take over the account even after the user updates their recovery email. What to Verify: • Is the old token still valid after changing the email? • Does the reset affect the current account owner? • Are all existing reset tokens revoked after sensitive account changes? • Does changing the password or email invalidate outstanding reset links? 🎯 Impact: High (Account Takeover) if an attacker can obtain or intercept an old password reset email. Always test only on accounts you own or are explicitly authorized to assess.
