# CVE-2026-123796: compose-lint: Incomplete fix for GHSA-jf3h-8jvx-vcrg: a run stopped at the finding limit quotes a secret from a CI-generated `.env`

Status: published. Published: 2026-11-09. Updated: 2026-11-09.

compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. From 0.32.0 until 0.33.0, compose-lint's incomplete remediation for .env secret disclosure checks the 20,000-finding limit before replacing resolved values with their variable references. A pull request can combine a secret-referencing image field with aliased content that produces more than 20,000 findings, causing the early-stop path to emit already graded findings with the resolved secret value in text, JSON, SARIF, and Code Scanning output. Exploitation requires a workflow that writes secrets into the sibling .env and lints untrusted changes, and the run exits 2 unless --allow-partial-coverage is used. This issue is fixed in version 0.33.0.
