Local vector because exploitation occurs on the victim's machine when processing the file; user interaction required to open the bundle; no confidentiality impact from file writes alone.

Lifecycle Timeline
2DescriptionCVE.org
A relative path traversal issue in the zip extraction functionality in AWS diagram-as-code (awsdac) in versions 0.10 through 0.23 can allow a third party to write arbitrary files to the local filesystem via crafted zip entry names containing path traversal sequences. This could allow the third party to perform inappropriate actions in the diagram bundle.
To remediate this issue, users should upgrade to the version 0.24 or later.
AnalysisAI
Zip extraction in AWS diagram-as-code (awsdac) versions 0.10 through 0.23 is vulnerable to relative path traversal (CWE-23), enabling a third party to write arbitrary files outside the intended extraction directory by embedding crafted path sequences in zip entry names within a malicious diagram bundle. Exploitation requires user interaction - a victim must actively process the attacker-supplied bundle - making this a social-engineering-dependent local attack. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The victim must actively process a malicious diagram bundle (zip file) using awsdac versions 0.10 through 0.23 - confirmed by the UI:A metric in the provided CVSS 4.0 vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:H) scores 6.8, reflecting a local attack requiring user interaction with high integrity and availability impact but no confidentiality exposure. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious diagram bundle zip file containing entries with path traversal sequences such as '../../cron.d/backdoor' or '../../.ssh/authorized_keys'. The bundle is distributed via a public diagram-sharing repository, email attachment, or community forum targeting awsdac users. … |
| Remediation | Upgrade awsdac to version 0.24 or later, which contains the hotfix addressing this path traversal issue per the GitHub release at https://github.com/awslabs/diagram-as-code/releases/tag/v0.24 and the AWS security bulletin at https://aws.amazon.com/security/security-bulletins/2026-090-aws/. … Detailed patch versions, workarounds, and compensating controls in full report. |
