Polygon Labs: Bor v2.1.3 released, fixing two DoS security vulnerabilities

Polygon Labs official announcement, Bor v2.1.3 is officially released to the public, previously distributed in private version form to validators and major infrastructure providers. This update fixes two medium-severity denial-of-service vulnerabilities in BlockSTM V2 parallel block execution, both submitted by security researchers through the Immunefi bug bounty program.Unbounded keccak256 cache issue: Attackers can fill hundreds of MiB of cache during the speculative execution phase by constructing specific transactions, leading to node memory exhaustion and delayed block production. The fix is to set a capacity limit on the shared cache. Repeated code hash calculation issue in parallel execution: A single transaction can cause the parallel processor to take about 11 seconds, severely affecting node activity. The fix is to cache code hash results on a per-transaction basis.In addition, this update also includes several internal hardening measures: the transaction pool address filtering adds interception for EIP-7702 SetCode authorization, RPC batch execution pool concurrency limit fixes, consistency fixes for reading balances across self-destruct boundaries in parallel execution, and an automatic cleanup mechanism for pending transactions (default 3 hours). The affected versions are Bor v2.1.1 and v2.1.2. v2.1.3 is a non-hard fork, and nodes can upgrade individually without coordination. No exploitation records of the two vulnerabilities have been found on the mainnet and testnet Amoy.

Sandeep Nailwal, CEO of the Polygon Foundation, stated that Polygon is preparing to deploy a permissionless burn contract that allows anyone to permanently burn 100 million POL, which accounts for approximately 83% of the 121 million tokens held by the Polygon base fee collector. The contract is currently live on the testnet and will be deployed to the mainnet after the security committee completes the final signature.The first round of burns will permanently destroy 100 million POL, after which community members can trigger burns every quarter. Polygon's documentation indicates that the base fee is determined by the network and will be burned, with Nailwal stating that each base fee will inject POL into the collector. Based on the above data, approximately 21 million POL will remain in the collector after the initial burn.This burn represents about 1% of the initial supply of 10 billion POL, and based on a total supply of approximately 10.716 billion as shown by Blockscout, it accounts for about 0.93%. The burn will not set a hard cap on POL, which will continue to be issued, with an annual issuance rate of about 2% after June 2025. Nailwal also mentioned that POL has entered deflation starting January 2026, citing data from his "ChatGPT Analyst" that Polygon's revenue in 2026 will be $24.5 million, higher than Arbitrum's $8.41 million and Near's $5.6 million.
