Denial of Service in GitLab Terraform state lock API
CVE-2026-1092 is a denial-of-service vulnerability in GitLab CE/EE affecting the Terraform state lock API. It impacts all versions from 12.10 before 18.8.9, 18.9 before 18.9.5, and 18.10 before 18.10.3. The issue is caused by improper input validation of JSON payloads: the API parses attacker-supplied JSON before authentication checks are fully enforced, allowing unauthenticated requests to reach a resource-intensive parsing path. Crafted malformed, oversized, or deeply nested JSON payloads can trigger excessive CPU and/or memory consumption during request processing, resulting in service degradation or outage.
