@grpc/grps-js: An incoming malformed compressed message can cause a client or server crash

Published Jul 14, 2026 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed

Description

@grpc/grps-js implements the core functionality of gRPC purely in JavaScript, without a C++ addon. Prior to 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, and 1.14.4, an invalid incoming compressed message can cause a client or server process that uses @grpc/grpc-js to crash. This issue is fixed in versions 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, and 1.14.4.

Analysis

Technical impact

An invalid incoming compressed message causes the @grpc/grpc-js library to crash, terminating client or server processes. The library is implemented purely in JavaScript, without any C++ native addon. The vulnerability is present in versions released before 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, and 1.14.4, and is fixed in those versions and later. This can be leveraged to perform a denial‑of‑service attack, disrupting service availability without compromising confidentiality or integrity. The weakness is identified as unchecked untrusted input.

Affected Systems

The vulnerability affects the grpc:grpc-node package, specifically versions released before 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, and 1.14.4. Updates to 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, and 1.14.4 and later releases contain the fix.

Risk and Exploitability

The CVSS score is 7.5, indicating a high severity. The EPSS score is less than 1%, suggesting a low exploitation probability, and the vulnerability is not listed in the CISA KEV catalog. An attacker can trigger the issue by sending a crafted compressed message over the network, making the attack vector likely remote and network‑based. While the likelihood of exploitation is low, the high impact warrants prompt remediation.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

Upgrade @grpc/grpc-js to version 1.9.16 or newer (at least 1.14.4)
After upgrading, restart all affected client and server processes to ensure the crash protection is active
If upgrading immediately is not feasible, configure the gRPC connections to disable compression so that malformed compressed messages cannot be processed
