Windmill is an open-source developer platform for internal code: APIs, background jobs, workflows and UIs. Prior to 1.715.0, a resource-scoped API token could read script contents outside its allowed path scope through GET /api/w/{workspace}/scripts/list_search. The route-level scope middleware validated the token domain and action but did not enforce the resource/path segment, and the list_search_scripts handler had no additional check_scopes call or per-row filtering before returning script path and content fields. A token such as scripts:read:f/allowed/* could therefore receive source code for unrelated paths in the same workspace, potentially disclosing internal automation logic, integration details, business logic, inline configuration, or hardcoded secrets and credentials. Exploitation required possession of a valid scoped API token for the workspace but did not require administrator privileges. This issue is fixed in version 1.715.0.

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. 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).
