Summary
Vulnerability in Nx (versions 20.8.0 to 22.7.7 and 23.0.2) in the self-hosted HTTP remote cache. A malicious cache server can return a crafted tar archive that writes files outside the cache directory, potentially leading to remote code execution.
Risk Assessment
An attacker could exploit this to gain control of the machine running Nx, posing a serious threat to system integrity.
Recommendation
Update Nx to version 22.7.7 or 23.0.2 and use only trusted cache servers.
Other vulnerabilities in Nx
See all- CVE-2026-104859High
Nx is a monorepo solution for TypeScript and polyglot codebases. From 21.4.0 until 22.7.8 and from 23.0.0 until 23.1.1, the @nx/docker release pipeline builds shell command strings from configuration values, which are executed via /bin/sh -c. This allows shell syntax in untrusted Nx configuration to execute during release operations, potentially exposing registry credentials or cloud tokens.
- CVE-2026-104854High
Nx from 14.6.0 until 22.7.9 and 23.1.2 creates Unix domain sockets for its daemon and isolated plugin workers in shared temporary locations without owner-only permissions. Another unprivileged local account can connect to a running socket because the transport performs no authentication. The daemon's PROCESS_IN_BACKGROUND request can execute code as the account running Nx. Fixed in versions 22.7.9 and 23.1.2.
- CVE-2026-104853Medium
Nx is a monorepo solution for TypeScript and polyglot codebases. From 13.10.0 until 22.7.10 and 23.2.1, Nx migration planning reads the nx-migrations.migrations value from a target package manifest without validating that it is a contained relative path. A hostile dependency can supply .. segments or an absolute path, causing the migration archive to write attacker-controlled bytes outside the temporary directory or truncate an existing writable file.
Original NVD description (English source)
Nx is a monorepo solution for TypeScript and polyglot codebases. From version 20.8.0 until 22.7.7 and 23.0.2, the Nx self-hosted HTTP remote cache extracts downloaded cache artifacts without constraining where files are written. A malicious or on-path (MITM) remote cache server can return a crafted tar archive whose entries escape the cache directory and write to arbitrary locations on the machine running Nx, which can be escalated to remote code execution. Nx's default local cache and Nx Cloud are not affected; only workspaces configured to use a self-hosted remote cache are affected. This issue is fixed in versions 22.7.7 and 23.0.2.
