A fix is available — apply it.

A flaw was found in the Ansible Automation Platform automation-controller. The WorkflowJobNode.ancestor_artifacts database column, which stores the raw merged set_stats artifacts propagated between workflow nodes, is not wrapped in prevent_search() and is therefore accepted for arbitrary field lookups by the REST filter backend, even though it is omitted from the API serializer. Because the column is persisted before Ansible's no_log masking is applied, a user with only read access to a workflow — or, via a regular-expression lookup that bypasses the JSON cross-relation filter guard through the world-readable credential-types endpoint, any authenticated user with no roles — can use the result count as a boolean/count oracle to recover, character by character, secret values that a playbook author explicitly marked no_log, including across organizations.

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. Higher = act sooner.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. 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".

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures).
