SpendProofV1 txid-substitution: get_spend_proof/check_spend_proof do not verify returned transaction hash
🔹 Severity: Medium
🔹 Weakness: Missing Required Cryptographic Step
🔹 Reported To: Monero
🔹 Reported By: bebensap
🔹 State: 🟢 Resolved
🔹 Disclosed: August 5, 2026, 10:23am (UTC)
🐞 Source: HackerOne
A vulnerability was discovered in the Monero project where the get_spend_proof and check_spend_proof functions do not verify the returned transaction hash against the requested transaction ID. This allows a malicious or compromised daemon to provide a valid serialized transaction body for a different transaction than the one requested, which can be used to create or verify a spend proof for that different…

A vulnerability was discovered in the Monero wallet software that could cause the wallet-rpc process to crash when handling a malformed response from the daemon's /gettransactions endpoint. The vulnerability was due to the wallet software making assumptions about the response structure that were not always valid, leading to undefined behavior when attempting to access empty data structures. The crash occurred when…

`check_reserve_proof` sums RingCT ECDH amounts without checking the output commitment

🔹 State: 🟢 Resolved
🔹 Disclosed: August 5, 2026, 10:23am (UTC)
🐞 Source: HackerOne
The `check_reserve_proof` function in the Monero codebase was found to sum RingCT ECDH amounts without checking the output commitment. The decoded amount was added to the total without verifying that it matched the commitment, which could allow a malicious prover to claim larger reserves than actually exist on-chain.

A vulnerability was found that allowed an attacker to add any phone number to a user's profile by brute-forcing the one-time password (OTP) used for phone number verification. The steps involved intercepting the OTP verification request, using a brute-force attack to find the valid OTP, and then replaying the original request with the discovered OTP to complete the phone number addition.
