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...

Uncaught Exception

Overview org.webjars.npm:tar is a full-featured Tar for Node.js. Affected versions of this package are vulnerable to Uncaught Exception through improper handling of NUL bytes in the src/pax.ts file. An attacker can cause the application to terminate unexpectedly by providing a crafted archive...

Allocation of Resources Without Limits or Throttling

Overview tar is a full-featured Tar for Node.js. Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the lack of enforced upper bounds on total decompressed data, entry counts, or decompression ratio in extraction and parsing paths such ...

Incorrect Type Conversion or Cast

Overview tar is a full-featured Tar for Node.js. Affected versions of this package are vulnerable to Incorrect Type Conversion or Cast via the src/pax.ts file. An attacker can cause a process crash by providing all-digit PAX path or linkpath values that are coerced to JavaScript numbers, leading ...

CVE-2026-59875

node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.17, node-tar does not strip NUL bytes from PAX path and linkpath records in src/pax.ts, allowing a crafted archive with values to reach fs.lstat or fs.open and terminate the process with an uncaught exception. This issue is...
