Researcher discovered a deserialization vulnerability in a JSF-based web application by identifying unencrypted serialized Java objects in the javax.faces.ViewState parameter, leading to remote code execution via JMX console exploitation and a $1500 bounty reward.
Researcher bypassed 2FA on www.domain.com by intercepting the login request with Burp Suite, changing the Host header to beta.domain.com (a parallel subdomain without 2FA enforcement), and submitting an arbitrary code (000000) to successfully authenticate. The vulnerability stemmed from inconsistent 2FA implementation across subdomains, fixed within one day but without bounty payout.
A bug bounty finding demonstrating a 2FA bypass via forced browsing by directly accessing an unprotected signup endpoint (/_ajax/signup instead of /_api/signup/verify), allowing account creation without OTP verification by modifying the API request to include password field.
A researcher discovered a SQL injection vulnerability in a trading company's web application through a hidden 'status' parameter in the report download endpoint, which was found using parameter mining techniques and exploited using time-based blind SQL injection.
An IDOR vulnerability in an e-commerce site's address management API exposed customer addresses and mobile numbers. Although direct address retrieval was protected by session validation, the attacker discovered that a POST request to set a default address with sequential address_id parameters returned HTTP 200 responses, and subsequent checkout page requests displayed other users' full addresses regardless of session context.
Researcher discovered a full account takeover vulnerability by chaining multiple weaknesses: a password change endpoint that accepted null CSRF tokens and lacked proper validation, combined with a hidden 'uid' parameter discoverable via Param Miner that allowed changing arbitrary users' passwords without authentication. The vulnerability earned a $1000 bounty.
A researcher discovered a critical $150,000 Evmos vulnerability by simply reading Cosmos documentation—sending funds to the distribution module account (which should be blocklisted) triggered invariant violations that halted the entire blockchain and all dependent dApps.
A critical DoS vulnerability in Stacks' Clarity virtual machine was discovered where an unhandled exception in the smart contract interpreter caused client nodes to crash when processing malicious contracts. The vulnerability was patched by modifying error handling to return proper exceptions instead of using `.expect()` calls.
A griefing vulnerability in Lido's Dual Governance RageQuit mechanism allowed permissionless prolongation of the RageQuit extension period, potentially blocking ETH withdrawals and protocol governance.
