Security Bulletin: Vulnerability in node-tar bundled with IBM Fusion, IBM Fusion HCI, and IBM Fusion Content-Aware Storage

Summary IBM Fusion, IBM Fusion HCI, and IBM Fusion Content-Aware Storage include the node-tar library, which is susceptible to a Path Traversal vulnerability during archive extraction. When default configurations are used, an attacker-controlled archive can create a hardlink inside the extraction...

CVE-2026-59874

A flaw was found in node-tar, a tar archive manipulation library for Node.js. A remote attacker could exploit this vulnerability by providing a specially crafted tar archive with a negative entry size in its header. This malformed header causes the archive scanner to enter an infinite loop,...

CVE-2026-59875

A flaw was found in node-tar, a library for manipulating tar archives in Node.js. A remote attacker could craft a malicious archive containing null characters NUL bytes in its metadata. When this archive is processed, the unstripped null characters can cause the application to terminate...

CVE-2026-59873

A flaw was found in node-tar, a tar archive manipulation library for Node.js. This vulnerability allows a remote attacker to craft a small gzip bomb, which, when processed, can lead to the exhaustion of disk space and CPU resources. This occurs because node-tar does not enforce strict limits on t...

CVE-2026-59871

A flaw was found in node-tar, a library for manipulating tar archives in Node.js. This vulnerability occurs when the library incorrectly converts specific archive path values into numbers, leading to an error during subsequent path processing. An attacker could exploit this to cause the applicati...

CVE-2026-53655

A flaw was found in node-tar. This vulnerability arises because node-tar incorrectly applies PAX extended header size records to subsequent intermediary metadata headers, leading to a desynchronization of the tar stream cursor compared to other standard tar implementations. A remote attacker coul...
