Summary
Workarounds
There are no workarounds known to this, please upgrade to Postiz version v2.21.1.
Impact
A successful SSRF attack allows an attacker to:
- Bypass firewalls to scan and interact with internal network services/ports.
- Access sensitive cloud metadata services (e.g., AWS IMDS 169.254.169.254) to potentially leak instance credentials.
- Pivot into the internal network environment where Postiz is hosted.
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.
GHSA-VJ2P-7PGW-G2WF has a CVSS score of 7.5 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. No fixed version is listed yet, so configuration controls and monitoring matter more in the interim.

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.
Remediation advice
In the interim: Validate and restrict destination URLs against an allowlist. Block requests to private IP ranges and cloud metadata endpoints.
Kodem Kai can prioritize this vulnerability in your dependency tree and generate a fix recommendation.
Frequently Asked Questions
- What is GHSA-VJ2P-7PGW-G2WF? GHSA-VJ2P-7PGW-G2WF is a high-severity server-side request forgery (SSRF) vulnerability in postiz (npm), affecting versions <= 2.0.12. 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.
- How severe is GHSA-VJ2P-7PGW-G2WF? GHSA-VJ2P-7PGW-G2WF has a CVSS score of 7.5 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of postiz are affected by GHSA-VJ2P-7PGW-G2WF? postiz (npm) versions <= 2.0.12 is affected.
- Is there a fix for GHSA-VJ2P-7PGW-G2WF? No fixed version is listed for GHSA-VJ2P-7PGW-G2WF yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is GHSA-VJ2P-7PGW-G2WF exploitable, and should I be worried? Whether GHSA-VJ2P-7PGW-G2WF 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 GHSA-VJ2P-7PGW-G2WF 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 GHSA-VJ2P-7PGW-G2WF? 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.
