  1. XRP Ledger fixes decade-old flaw that could have minted XRP

    Researchers Cayden Liao and Veria AI reported on 22 September a payment flaw in XRP Ledger dating to 2015 that could have let attackers generate and spend XRP beyond the 100bn cap. RippleX reproduced it, said there is no evidence it was exploited on public networks, and released xrpld 3.4.1 on 25 September.

  2. RippleX says XRPL flaw could have allowed excess XRP creation

    RippleX engineering lead J. Ayo Akinyele said a critical flaw in the XRP Ledger payment engine, present for over 10 years, could theoretically have created XRP beyond its fixed supply. He said Veria AI found it through Ripple's bug bounty programme and the fix was tested and deployed with validators before disclosure.

  3. XRP Ledger Foundation says security fix did not mint new XRP

    The XRP Ledger Foundation said a recently patched vulnerability did not create new XRP, with supply fixed at 100 billion and about 99.986 billion XRP in existence. It said the flaw was fixed in version 3.4.1 and that community consensus drove the patch.

  4. ZachXBT says XRPL paid white-hat hacker only $250,000

    On-chain detective ZachXBT criticised the XRP Ledger Foundation for paying a white-hat hacker only $250,000 for finding a severe 'unlimited XRP minting' vulnerability, saying the low reward may deter responsible reporting. The foundation said the flaw did not mint XRP and was patched by community consensus.

  5. XRPL lending bug fix due around 23 Oct, pending validator support

    The XRP Ledger patch fixCleanup3_4_0 is expected to activate around 09:34 UTC on 23 Oct after 29 validators backed it, CoinDesk reported. That is the minimum threshold, so one withdrawal restarts the countdown, and activation would not mean final approval for the lending feature.
