Volt, a widely adopted functional API for Livewire, has recently patched a critical remote code execution (RCE) vulnerability tracked as CVE-2025-27517. With over 1.08 million downloads, Volt enables developers to seamlessly integrate PHP logic and Blade templates within single-file components. However, a flaw in its request-handling mechanism has been identified, posing a significant security risk.
Volt’s streamlined approach to component development leverages user inputs and dynamic request processing. However, according to the security advisory, this very mechanism introduced an exploitable flaw: “Malicious, user-crafted request payloads could potentially lead to remote code execution within Volt components.”
Attackers exploiting this vulnerability could craft specially designed payloads to execute arbitrary PHP code within vulnerable Volt-powered applications. This could lead to
- Full system compromise, allowing attackers to manipulate or exfiltrate sensitive data.
- Privilege escalation, giving adversaries administrative access to the affected system.
- Deployment of further malware, such as web shells or backdoors, for persistent access.
Given its CVSSv4 score of 9.3, this vulnerability is classified as critical, underscoring the urgency of applying the fix.
The Volt team has swiftly addressed this issue in version 1.7.0, effectively mitigating the RCE risk. Users running previous versions are strongly advised to upgrade immediately to safeguard their applications.
