Lifecycle Timeline
2DescriptionCVE.org
Carbone is vulnerable to Denial of Service due to lack of protection against zip bombs when processing .docx files. The library uses yazl for zip decompression without validating entry sizes, allowing an attacker to supply a malicious .docx file containing a zip bomb that decompresses to a significantly larger size, causing excessive memory consumption and crashing the application server.
The issue was fixed in versions: 3.8.2, 4.26.3 and 5.4.4. The fix is available across all distribution types.
AnalysisAI
Denial of service in Carbone, a Node.js document generation library, allows remote attackers to crash application servers by supplying a maliciously crafted zip bomb embedded in a .docx template file. The library processed .docx archives (which are ZIP containers) using yazl without enforcing any limit on decompressed entry sizes, enabling an attacker-controlled file to trigger runaway memory allocation that terminates the Node.js process. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must be able to deliver a .docx file as a template input to a Carbone rendering operation - this typically means access to an HTTP endpoint, file upload interface, or API that accepts user-supplied .docx templates and passes them to Carbone for processing. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:A/VA:H/SA:L) scores 6.9, reflecting low attack complexity and no authentication requirement, tempered by the need for active user interaction (UI:A) - a user or automated process must submit the malicious file for rendering. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade Carbone to version 3.8.2, 4.26.3, or 5.4.4 according to the major version branch in active use; the patch is available across all distribution types and was confirmed via commit eb9b4cff992cc1cb1a319d7fc0cbd09160dc214e at https://github.com/carboneio/carbone/commit/eb9b4cff992cc1cb1a319d7fc0cbd09160dc214e. … Detailed patch versions, workarounds, and compensating controls in full report. |
