AI Analysis
Technical Summary
CVE-2026-14978 describes a vulnerability in HashiCorp go-slug versions 0.4.0 through 0.18.2. The issue arises from improper handling of Unicode normalization in path matching logic, specifically affecting the processing of .terraformignore exclusions. A local attacker could exploit this to bypass these exclusions and cause sensitive files to be included in Terraform slug uploads.
Potential Impact
The vulnerability allows a local attacker to bypass .terraformignore exclusions, potentially causing sensitive files to be included in Terraform slug uploads. This could lead to unintended exposure of sensitive information. The CVSS score is 5.5 (medium severity), indicating a moderate impact with confidentiality affected but no integrity or availability impact.
Mitigation Recommendations
No patch or official fix information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should exercise caution with local file handling and review .terraformignore configurations carefully.
