Summary
Possible privilege escalation via bash completion script
The bash completion script for fscrypt through v0.3.2 allows injection of commands via crafted mountpoint paths, allowing privilege escalation under a specific set of circumstances. A local user who has control over mountpoint paths could potentially escalate their privileges if they create a malicious mountpoint path and if the system administrator happens to be using the fscrypt bash completion script to complete mountpoint paths. We recommend upgrading to v0.3.3 or above.

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.

- What is GHSA-W4F8-FXQ2-J35V? GHSA-W4F8-FXQ2-J35V is a medium-severity security vulnerability in github.com/google/fscrypt (go), affecting versions < 0.3.3. It is fixed in 0.3.3.
- Which versions of github.com/google/fscrypt are affected by GHSA-W4F8-FXQ2-J35V? github.com/google/fscrypt (go) versions < 0.3.3 is affected.
- Is there a fix for GHSA-W4F8-FXQ2-J35V? Yes. GHSA-W4F8-FXQ2-J35V is fixed in 0.3.3. Upgrade to this version or later.
- Is GHSA-W4F8-FXQ2-J35V exploitable, and should I be worried? Whether GHSA-W4F8-FXQ2-J35V 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-W4F8-FXQ2-J35V 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.
