The EPSS score of less than 1% suggests that exploitation is unlikely at present, and the vulnerability is not in the CISA KEV catalog.

In many CI/CD pipelines, an internal or compromised user who can invoke the tool or a misconfigured build environment can generate a report that exposes secrets, resulting in a loss of confidentiality."}}}}, "created": "2026-02-25T11:34:42.492878+00:00", "updated": "2026-04-18T17:45:06.064305+00:00", "vendors": ["oocx", "oocx$PRODUCT$tfplan2md"]}
