CVE-2026-48069 is a high-severity vulnerability in the grpc-node library (@grpc/grpc-js) where an invalid incoming compressed message can cause a client or server process to crash due to an uncaught exception. This affects multiple versions prior to 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, and 1.14.4. The issue is fixed in these specified versions.
AI Analysis
Technical Summary
@grpc/grpc-js, a JavaScript implementation of gRPC without a C++ addon, contains a vulnerability identified as CVE-2026-48069. Specifically, versions prior to 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, and 1.14.4 are susceptible to crashes caused by invalid incoming compressed messages that trigger uncaught exceptions. This denial-of-service condition affects both client and server processes using the affected versions. The vulnerability is categorized under CWE-248 (Uncaught Exception). The issue has been addressed in the listed fixed versions.
Potential Impact
An attacker can send a specially crafted invalid compressed message to a client or server using the affected grpc-node versions, causing the process to crash. This results in a denial-of-service (DoS) condition. There is no impact on confidentiality or integrity reported. The CVSS v3.1 base score is 7.5 (high), reflecting network attack vector, low attack complexity, no privileges required, no user interaction, and impact limited to availability.
Mitigation Recommendations
Upgrade to one of the fixed versions: 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, or 1.14.4. These versions contain the fix for the uncaught exception caused by invalid compressed messages. No other mitigation or workaround is indicated. Patch status is confirmed by the vendor-stated fixed versions.
