DescriptionCVE.org

node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.19, node-tar does not enforce hard upper bounds on total decompressed data, entry counts, or decompression ratio in extraction and parsing paths such as src/extract.ts, allowing a small crafted gzip bomb to exhaust disk space and CPU. This issue is fixed in version 7.5.19.

AnalysisAI

Uncontrolled resource consumption in node-tar before 7.5.19 lets a small crafted gzip bomb exhaust disk space and CPU on any Node.js application that extracts or parses attacker-supplied tar archives. Because node-tar imposes no upper bound on total decompressed size, entry count, or compression ratio in its extract and parse paths, a tiny malicious file can inflate to consume all available storage and processing, causing denial of service. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that the target application uses node-tar (prior to 7.5.19) to extract or parse an archive whose bytes the attacker can influence - i.e., the app must ingest untrusted, externally-supplied gzip tar input through the extract or parse paths in src/extract.ts. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment Signals are consistent and point to a genuine availability risk rather than an inflated high-CVSS artifact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker uploads a few-kilobyte crafted gzip-compressed tar file to any service that automatically extracts it with a vulnerable node-tar - for example a CI pipeline, package registry mirror, or file-upload endpoint. During extraction the archive inflates to gigabytes, filling the disk and pinning CPU, which crashes the service or the host. …
Remediation Vendor-released patch: upgrade node-tar to version 7.5.19 or later, which introduces enforced upper bounds on total decompressed data, entry counts, and decompression ratio (fixing commit 2812e9338665659b183aa7226518c307044957d3; release https://github.com/isaacs/node-tar/releases/tag/v7.5.19; advisory https://github.com/isaacs/node-tar/security/advisories/GHSA-23hp-3jrh-7fpw). … Detailed patch versions, workarounds, and compensating controls in full report.
