Introduction
Remote code execution over a network can disrupt development pipelines and expose sensitive assets. In CVE-2025-55322, improper IP address binding in GitHub's infrastructure exposes services to unauthorized access. The issue has a CVSS score of 7.3 and concerns unrestricted network exposure, so it is relevant to any organization that uses GitHub for source code management or CI/CD workflows.
Technical information
CVE-2025-55322 comes from binding services to an unrestricted IP address, specifically 0.0.0.0. According to CWE-1327, this configuration makes the service listen on all available network interfaces, not only the ones intended for trusted access. In network programming, using 0.0.0.0 or an empty string as the bind address is equivalent to INADDR_ANY, which allows connections from any interface.
The vulnerability can arise when developers or system administrators configure a service (such as a web server or internal API) to bind to 0.0.0.0, which makes it reachable from any network the host is connected to. Attackers can scan for exposed services like these. If the service logic is flawed or lacks proper authentication, they can attempt remote code execution. dbt-core had a similar issue (CVE-2024-36105), where documentation servers were exposed unintentionally because they bound to INADDR_ANY. No public code snippets or proof-of-concept exploits are available for CVE-2025-55322.
Affected systems and versions
No specific product versions or configuration ranges have been published for CVE-2025-55322. The vulnerability is described as affecting GitHub infrastructure where services are bound to unrestricted IP addresses. Public sources give no further detail.
Vendor security history
GitHub, part of Microsoft, is the largest development platform globally. Its security history includes:
- Rapid response to the Shai-Hulud worm (September 2025), which exploited NPM package workflows
- Multiple GitHub Actions workflow vulnerabilities
- Implementing two-factor authentication, secret scanning, and supply chain security features
Even so, the complexity of GitHub's ecosystem and its integration with other Microsoft services have led to recurring problems with workflow and infrastructure security.
