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

The CVE record's description, written by its CNA (MITRE Corporation), states the affected versions: "An issue was discovered in Kiamo before 8.4 allowing authenticated administrative attackers to execute arbitrary PHP code on the server." No release containing a fix is confirmed on record.

An issue was discovered in Kiamo before 8.4 allowing authenticated administrative attackers to execute arbitrary PHP code on the server. NOTE: the Supplier's position is that this is "a historical and intended administrative feature of the product, accessible only to already authenticated users explicitly granted administrator privileges." However, restrictions on some PHP functions were added in 8.4.

EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).

SSVC (CISA's decision table, applied by EchelonGraph)Track at low, Track* at medium and Attend at high mission impact.

No fix is confirmed yet. Restrict network exposure of the affected system within your standard update timelines at low or medium mission impact and sooner than that at high, and watch for a fix.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (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".

MITRE Common Weakness Enumeration — the root-cause categories this CVE belongs to.

Data Freshness Timeline

(refreshed 11× in last 7d / 28× 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 99 of 226 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. 1 repeat row among the latest 100 is merged into the row it repeats. The 127 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

CVE-2025-70364 is a high-severity vulnerability; its CVE record was published on April 9, 2026. An issue was discovered in Kiamo before 8.4 allowing authenticated administrative attackers to execute arbitrary PHP code on the server. NOTE: the Supplier's position is that this is "a historical and intended administrative feature of the product, accessible only to already authenticated users…
When was the CVE record for CVE-2025-70364 published?
The CVE record for CVE-2025-70364 was published on April 9, 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 July 5, 2026; the record at its source may have been updated since.
Is CVE-2025-70364 actively exploited?
CVE-2025-70364 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.3% probability of exploitation in the next 30 days (19th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2025-70364?
CVE-2025-70364 has a CVSS v3.1 base score of 8.8 (CISA-ADP / Vulnrichment enrichment; NVD's own analysis pending).
How do I remediate CVE-2025-70364?
No fix for CVE-2025-70364 is confirmed yet. Until one is published, restrict network exposure of the affected system — for example, keep it off the internet or limit it to trusted networks — and watch for a fix. The CVE record's description, written by its CNA (MITRE Corporation), states the affected versions: "An issue was discovered in Kiamo before 8.4 allowing authenticated administrative attackers to execute arbitrary PHP code on the server." No release containing a fix is confirmed on record.
