The CVE record names the fixed release — apply it.

Pathling is a set of tools that make it easier to use FHIR and clinical terminology within health data analytics. Prior to version 2.0.0 of Pathling Server, Pathling's /$result endpoint allows a caller who can obtain any valid async export job ID to supply file parameter values containing path traversal sequences. The handler verifies only the supplied job and never normalises or confines the requested file path to that job's jobs/ directory before opening it as a filesystem resource. Because async export scratch space lives under the same warehouse database root as persisted resource tables, an attacker can use their own export job to read other files from the warehouse. This is fixed in Pathling Server 2.0.0. As an interim mitigation, disable the async export operations (pathling.operations.exportEnabled, patientExportEnabled, groupExportEnabled, bulkSubmitEnabled) or enable authentication and restrict export capability to trusted callers.

Exploitation public PoC (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). Most recent first.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. None are among the latest 100 rows. The 12 oldest rows on record are not shown and were not checked, so the counts can still include repeats.
