Summary
A critical vulnerability has been identified at https://security.snyk.io/package/linux/chainguard:latest/terraform-provider-sendgrid, associated with the underlying Go version.
If the server's TLS configuration is mutated between connections, for example, a CA is removed from the trusted list via Config.Clone() combined with modification or GetConfigForClient, the resumed handshake still succeeds using the cached session. The certificate is not re-checked against the updated CA list.
As a result, a client whose CA was revoked or removed between the first and second connection could still establish a connection on the resumed session.
Details
If the server's TLS configuration is mutated between connections, for example, a CA is removed from the trusted list via Config.Clone() combined with modification or GetConfigForClient, the resumed handshake still succeeds using the cached session. The certificate is not re-checked against the updated CA list.
Consequently, a client whose CA was revoked or removed between the first and second connection could still establish a connection on the resumed session.
Impact
GHSA-J443-WCQQ-XPRH has a CVSS score of 10.0 (Critical). 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.

Kodem Kai can prioritize this vulnerability in your dependency tree and generate a fix recommendation.
Frequently Asked Questions
- What is GHSA-J443-WCQQ-XPRH? GHSA-J443-WCQQ-XPRH is a critical-severity security vulnerability in github.com/arslanbekov/terraform-provider-sendgrid (go), affecting versions <= 1.1.3-0.20250606002314-b4a2dfeb7b0f. No fixed version is listed yet.
- How severe is GHSA-J443-WCQQ-XPRH? GHSA-J443-WCQQ-XPRH has a CVSS score of 10.0 (Critical). 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 github.com/arslanbekov/terraform-provider-sendgrid are affected by GHSA-J443-WCQQ-XPRH? github.com/arslanbekov/terraform-provider-sendgrid (go) versions <= 1.1.3-0.20250606002314-b4a2dfeb7b0f is affected.
- Is there a fix for GHSA-J443-WCQQ-XPRH? No fixed version is listed for GHSA-J443-WCQQ-XPRH yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is GHSA-J443-WCQQ-XPRH exploitable, and should I be worried? Whether GHSA-J443-WCQQ-XPRH 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-J443-WCQQ-XPRH 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.
