A GitHub-reviewed security advisory, not necessarily under active exploitation the way our CISA KEV advisories are, but a real, disclosed vulnerability in an open-source dependency.
Affected packages
Vulnerable: < 1.13.6
Patched in 1.13.6
Vulnerable: >= 1.14.0, < 1.14.5
Patched in 1.14.5
Details
If an application method handler crashes, the error message is included in the status message sent to the client. This can leak to the client any sensitive data that may be included in the error message. This impacts anyone using @grpc/grpc-js to run servers.
This vulnerability is fixed in 1.13.6 and 1.14.5.
This can be avoided by using a top-level error handler in method handlers to strip out sensitive error information.
EPSS, exploit probability
Low0.25%
estimated chance of real-world exploitation in the next 30 days, higher than 16.6% of every CVE FIRST.org scores
Refreshed 11/14/2026, via FIRST.org's EPSS model, not CVSS, this measures likelihood of exploitation, not how severe it would be.
