Introduction
Remote code execution over a network can disrupt development pipelines and expose sensitive assets. CVE-2025-55322 highlights a real-world risk in GitHub's infrastructure where improper IP address binding exposes services to unauthorized access. With a CVSS score of 7.3 and a focus on unrestricted network exposure, this issue is relevant for any organization relying on GitHub for source code management or CI/CD workflows.
Technical Information
CVE-2025-55322 is rooted in the practice of binding services to unrestricted IP addresses, specifically 0.0.0.0. According to CWE-1327, this configuration causes the service to listen on all available network interfaces, not just those 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.
This 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, making it accessible from any network the host is connected to. Attackers can scan for such exposed services and, if the service logic is flawed or lacks proper authentication, attempt remote code execution. A similar issue was observed in dbt-core (CVE-2024-36105), where documentation servers were unintentionally exposed due to binding 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. No further granularity is available in public sources.
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
- Implementation of two-factor authentication, secret scanning, and supply chain security features Despite these efforts, the complexity of GitHub's ecosystem and its integration with other Microsoft services have led to recurring challenges with workflow and infrastructure security.
