These vulnerabilities underscore ongoing risks in complex decentralized systems.\n\n### 1. **ERC-1363 Reentrancy Bypass (March 2026)**\nA novel reentrancy attack vector was discovered in implementations of the ERC-1363 token standard, which supports callback functions during transfers. Attackers exploited the `onTransferReceived` hook to reenter functions before state updates, draining funds from staking contracts. At least three DeFi protocols—YieldX, StakeVortex, and LiquiDex—were affected, resulting in $47 million in losses before patches were deployed.\n\n- **CVE ID**: CVE-2026-31482  \n- **Affected Protocols**: YieldX, StakeVortex, LiquiDex  \n- **Root Cause**: Improper use of the Checks-Effects-Interactions pattern  \n- **Source**: [Immunefi Advisory – ERC-1363 Reentrancy](https://immunefi.com/advisory/erc1363-reentrancy-2026/)  \n\n### 2. **Cross-Chain Message Relay Signature Malleability (February 2026)**\nA vulnerability in the ChainBridge-based messaging layer of the Polaris Bridge (connecting Ethereum and Polygon) allowed attackers to modify relayed transaction signatures, leading to duplicate message execution. This flaw enabled a replay attack that minted 1.2 million synthetic USDC on Polygon, causing a temporary depegging event.\n\n- **CVE ID**: CVE-2026-29811  \n- **Losses**: ~$60 million (mostly recovered via emergency freeze)  \n- **Fix**: Implemented strict signature validation and nonce chaining  \n- **Source**: [ChainSecurity Report – Polaris Bridge Flaw](https://chainsecurity.com/polaris-bridge-vulnerability-march2026)  \n\n### 3. **Orbital Oracle Timestamp Dependency Exploit (January 2026)**\nThe \"Orbital\" decentralized oracle network was found to expose timestamp data from untrusted ","keywords":["web3","blockchain","zo-research","blockchain-web3","defi"],"about":[],"citation":[],"isPartOf":{"@type":"Dataset","name":"Forge Cascade Knowledge Graph","url":"https://forgecascade.org"},"publisher":{"@type":"Organization","name":"Forge Cascade","url":"https://forgecascade.org"}}
