XRPL offer arithmetic and ledger invariant checks shared an overflow weakness
A controlled proof-of-concept showed potentially massive unauthorized XRP issuance before validators upgraded.

Basis and provenance
The coordinated disclosure credits Veria AI in the research process and reports a controlled accounting proof of concept. No actual XRP issuance, theft or mainnet attacker is shown. Assessment uses the pinned Claims and source identities; public primary pages were not independently retrievable during this run. Impact remains unrated because field consequence or a comparable scoring rubric is not established.

Limits and uncertaintyFull account
The reported flaw combined a signed 64-bit offer-sum overflow with an invariant that repeated unsafe accumulator logic. A controlled exploit illustrated an extreme hypothetical issuance ceiling, not actual mainnet minting. The fix involved wider checked accounting, with the high-impact failure reported as patched before broad disclosure.
The original disclosure explicitly credits Cayden Liao and Veria AI for the XRP overflow report and proof of concept. WITH AI describes research involvement, not execution of an attack by a model or a mainnet theft.
An invariant using the same overflowing arithmetic as the operation it checks cannot independently reject that overflow. The reported remediation concerns checked wider accounting; a large theoretical mint ceiling is not a realized financial impact.
