CVE-2026-111719

17th percentile - higher than 17% of all known CVEs

Roncoo-pay through commit 9428382 contains a missing authorization vulnerability in F2FPayController.orderQuery that allows unauthenticated attackers to retrieve payment records by supplying a trxNo parameter. Attackers can guess transaction numbers, a '7' prefix plus a snowflake ID, to obtain the full serialized payment record of any merchant.

An unauthenticated attacker can access confidential payment records of other merchants, constituting a serious breach of data confidentiality. This may lead to financial information leakage and fraud.

Update Roncoo-pay to a version containing the fix. Until deployment, consider restricting access to the orderQuery endpoint and monitoring unusual transaction queries.
