GoCD is a continuous deliver server. From 18.7.0 until 26.1.0, the Get Template Config API compares HTTP method names case-sensitively when selecting authorization filters. A lower-privileged authenticated user can send a request with nonstandard HTTP method capitalization to retrieve a pipeline template by name without the required view permission and read its configuration. API operations that modify data are not affected, secure variables remain encrypted, and deployments whose reverse proxy rejects non-uppercase HTTP methods are not affected. This issue is fixed in version 26.1.0.

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first.

Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".
