CVE-2026-47878

HIGHNVD 7.37.3
EchelonGraph scoreMEDIUM confidence

“—” beside the score: it is equal to NVD's CVSS score.

This high-severity CVE scores 7.3 under NVD CVSS v3. EPSS exploit probability: 0.4% (26th percentile of EPSS-scored CVEs). GitHub Security Advisory CVSS 5.6 is lower than this score; a lower GitHub score revises it only when its advisory is newer than the CVE record's last change, and this advisory (published 2026-08-27) is not newer than that change (2026-09-10), so it does not.

No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The CVE record's CNA (VMware by Broadcom) lists Spring Batch versions 6.0.0 up to and including 6.0.4 and up to and including 5.2.6 as affected. No release containing a fix is confirmed on record.

DefaultExecutionContextSerializer, used by default in Spring Batch's JDBC job repository, passes Base64-decoded bytes directly to ObjectInputStream.readObject() without an ObjectInputFilter that restricts types to a trusted class allowlist. Spring Batch 6.0.0 - 6.0.4 Spring Batch 5.2.6 and earlier

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".

Data Freshness Timeline

(refreshed 17× in last 7d / 92× in last 30d)

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.

Showing the most recent 100 of 147 refreshes on record for this CVE.

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 47 oldest rows on record are not shown and were not checked, so the counts can still include repeats.
