Three AI coding agents leaked secrets through a single prompt injection
VentureBeat·medium signal
VentureBeat documents three AI coding agents that leaked secrets via one prompt-injection payload, with one vendor's system card having predicted exactly this runtime failure mode. The piece argues agent runtime security needs audit, comment, and control layers because allowlisting and static review miss injection that weaponizes the agent's own permitted actions. For builders, it reinforces treating coding-agent execution environments as untrusted and instrumenting them at runtime, not just at the prompt boundary.
