CVE-2026-27900
This issue is exposed when debug/provider logs are explicitly enabled (for example in local troubleshooting, CI/CD jobs, or centralized log collection).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.47%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The Terraform Provider for Linode versions prior to v3.9.0 logged sensitive information including some passwords, StackScript content, and object storage data in debug logs without redaction. Provider debug logging is not enabled by default. This issue is exposed when debug/provider logs are explicitly enabled (for example in local troubleshooting, CI/CD jobs, or centralized log collection). If enabled, sensitive values may be written to logs and then retained, shared, or exported beyond the original execution environment. An authenticated user with access to provider debug logs (through log aggregation systems, CI/CD pipelines, or debug output) would thus be able to extract these sensitive credentials. Versions 3.9.0 and later sanitize debug logs by logging only non-sensitive metadata such as labels, regions, and resource IDs while redacting credentials, tokens, keys, scripts, and other sensitive content. Some other mitigations and workarounds are available. Disable Terraform/provider debug logging or set it to `WARN` level or above, restrict access to existing and historical logs, purge/retention-trim logs that may contain sensitive values, and/or rotate potentially exposed secrets/credentials.
