CVE-2026-61694: go-xrpl is a Go implementation of the XRP Ledger protocol. In versions through the June 18, 2026 revision identified by the advisory, `ParseMPTAmountBinary` in `internal/ledger/state/ripple_state.go` converts the eight-byte MPT magnitude using `num.Int64()` without checking that it fits in 63 bits. A positive magnitude of at least 2^63 silently wraps into a negative amount without an error. `ParseEscrow` passes 33-byte `sfAmount` fields to the parser and stores `MPTRaw()` in `EscrowData.MPTAmount`, causing incorrect downstream calculations and divergence from rippled's interpretation of the same escrow entry. Independently, `readMPTAmount` in `internal/tx/ledgerfields/decode_stream.go` accepts over-limit magnitudes and surfaces large decimal strings without enforcing the maximum signed 64-bit value. The public codec in codec/binarycodec/types/amount.go already rejects these values, leaving the internal decoders inconsistent with that safe path. A source fix is available in commit 9dbd3935ed6c54f0232f2291edf9c012a0900dd5.
The exploitability of CVE-2026-61694 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
CVE-2026-61694 presents a challenge to exploit due to its high attack complexity, but the absence of privilege requirements still makes it a viable target for skilled attackers. A thorough security review is advised.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2026-61694, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2026-61694, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
