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 Cloud Foundry Foundation BOSH Director versions before 282.1.12 as affected. No release containing a fix is confirmed on record.

AgentClient#handle_method (lines 264-303) processes every NATS reply. It calls inject_compile_log (line 273) on every response, which reads response['value']['result']['compile_log_id'] (line 332-338) and passes it to download_and_delete_blob. Separately, any response containing 'exception' goes through format_exception (lines 308-325), which reads exception['blobstore_id'] and also calls download_and_delete_blob. That helper (lines 344-349) calls ResourceManager#get_resource(blob_id) and, in an ensure block, ResourceManager#delete_resource(blob_id). ResourceManager (resource_manager.rb:62-70) calls blobstore.delete(id) on the single shared Director blobstore with no UUID-format check, no ownership check, and no namespace prefix.

EG Risk 23/100

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".

Data Freshness Timeline

(refreshed 6× in last 7d / 26× 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 98 of 168 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. 2 repeat rows among the latest 100 are merged into the row they repeat. The 70 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

Frequently asked(5)

What is CVE-2026-41704?
CVE-2026-41704 is a medium-severity vulnerability; its CVE record was published on May 27, 2026. AgentClient#handlemethod (lines 264-303) processes every NATS reply. It calls injectcompilelog (line 273) on every response, which reads response['value']['result']['compilelogid'] (line 332-338) and passes it to downloadanddeleteblob. Separately, any response containing 'exception' goes through…
When was the CVE record for CVE-2026-41704 published?
The CVE record for CVE-2026-41704 was published on May 27, 2026. That is the record's publication date; the vulnerability itself may have been made public earlier. EchelonGraph's copy of the record carries a last-modified date of June 8, 2026; the record at its source may have been updated since.
Is CVE-2026-41704 actively exploited?
CVE-2026-41704 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.1% probability of exploitation in the next 30 days (1st percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-41704?
CVE-2026-41704 has a CVSS base score of 5.0 (a secondary CVSS source that NVD displays; NVD's own analysis pending).
How do I remediate CVE-2026-41704?
No fix for CVE-2026-41704 is confirmed yet. Until one is published, restrict network exposure of the affected system or apply the vendor's mitigation — for example, keep it off the internet or limit it to trusted networks — and watch the vendor's advisory for the fix. The CVE record's CNA (VMware by Broadcom) lists Cloud Foundry Foundation BOSH Director versions before 282.1.12 as affected. No release containing a fix is confirmed on record. The vendor advisories EchelonGraph has for CVE-2026-41704 are linked in the Vendor Advisories panel on this page.
