Summary
LNbits Lightning Network Payment System Vulnerable to Server-Side Request Forgery via LNURL Authentication Callback
Impact
This vulnerability allows authenticated attackers to access internal network resources that should not be accessible from the internet. While authentication is required to exploit this vulnerability, any user who can create a wallet gets the necessary access level. The vulnerability can be used to read internal files, access internal services, and potentially expose sensitive information from the internal network.
Untrusted input controls the target URL of a server-initiated request, which may reach internal services not otherwise accessible from outside. Typical impact: access to internal metadata services, internal APIs, or cloud credentials.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2025-32013? CVE-2025-32013 is a critical-severity server-side request forgery (SSRF) vulnerability in lnbits (pip), affecting versions <= 0.12.12. No fixed version is listed yet. Untrusted input controls the target URL of a server-initiated request, which may reach internal services not otherwise accessible from outside.
- Which versions of lnbits are affected by CVE-2025-32013? lnbits (pip) versions <= 0.12.12 is affected.
- Is there a fix for CVE-2025-32013? No fixed version is listed for CVE-2025-32013 yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is CVE-2025-32013 exploitable, and should I be worried? Whether CVE-2025-32013 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-32013 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2025-32013? No fixed version is listed yet. In the interim: Validate and restrict destination URLs against an allowlist. Block requests to private IP ranges and cloud metadata endpoints.
