BTCPay Server has confirmed that funds can be stolen through a critical flaw that is being actively exploited in the wild, turning a security disclosure into a live threat for operators of the self-hosted Bitcoin payment processor.
The project has stated that the vulnerability allows funds to be stolen, framing the issue as a confirmed incident rather than a rumor or theoretical risk, according to its own disclosure. For related coverage, see Spot Bitcoin ETFs Post $853.54M Weekly Net Inflows.
BTCPay Server also warned that the flaw is being actively exploited and may drain funds, a point echoed in reporting on the active exploit. For related coverage, see Brazil Targets Crypto Fraud With 24-Hour Hold on Transfers Over $10K.
WHAT TO KNOW
Details such as total losses, the specific attack vector, and the full range of affected deployments are not confirmed in the available material, so they are left out here rather than estimated. This mirrors an earlier case in which a Bitcoin payment processor confirmed funds were stolen before the scope was fully clear.
An actively exploited flaw differs sharply from a routine disclosure. A disclosed vulnerability is a weakness that has been found; an actively exploited one is being used against real deployments right now, which is the situation BTCPay Server has described.
Because the flaw involves funds rather than only data or uptime, the impact lands directly on operators holding value, a dynamic seen in a recent exploit that drained Lightning payment servers across Bitcoin infrastructure.
The severity has drawn wider attention, with Forbes noting the incident as part of a deepening security scare hitting major Bitcoin projects. There is no evidence in the available material of contagion beyond the affected software itself.
BTCPay Server is self-hosted, so each operator is responsible for applying fixes. The immediate priority is to monitor the project’s official advisories and patch guidance, including its security advisory channel, for confirmed mitigation steps.
BTCPay Server has also communicated the warning through its official account on X, the direct channel operators should track for updates.
Security advisory: a critical vulnerability is being actively exploited and funds can be stolen. Please review our advisory and take action immediately. https://blog.btcpayserver.org/btcpay-server-vulnerability-funds-can-be-stolen/

Operators weighing an emergency response can review how a prior BTCPay emergency patch exposed merchant-side risk, then apply official mitigation only as the project confirms it. Specific upgrade paths should follow BTCPay Server’s own instructions rather than any secondhand summary.
