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

The CVE record's CNA (WatchGuard Technologies, Inc.) lists WatchGuard AP versions 1.0 up to but not including 3.4.8 as affected. No release containing a fix is confirmed on record.

An OS command injection vulnerability in the WatchGuard AP internal API service allows an attacker with network access to the AP to execute arbitrary shell commands on the underlying operating system.

EG Risk 58/100

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.

SSVC (CISA's decision table, applied by EchelonGraph)Track at low or medium mission impact; Attend at high (mission-essential systems).

No fix is confirmed yet. Check the vendor's advisory for a fixed release; until one is applied, restrict network exposure of the affected system or apply the vendor's mitigation on your normal schedule at low or medium mission impact and sooner than that at high.

Exploitation none (CISA Vulnrichment) · Automatable yes (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".

No released fix is confirmed on this page, but CISA's timeline does not wait for a fix's release: it starts when an agency identifies the flaw on an asset and updates the CDM Agency and Federal Dashboard, and the directive counts patching, decommissioning the system or another action as remediation.

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.

Frequently asked(5)

What is CVE-2026-86102?
CVE-2026-86102 is a critical-severity vulnerability; its CVE record was published on September 28, 2026. An OS command injection vulnerability in the WatchGuard AP internal API service allows an attacker with network access to the AP to execute arbitrary shell commands on the underlying operating system.
When was the CVE record for CVE-2026-86102 published?
The CVE record for CVE-2026-86102 was published on September 28, 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 September 28, 2026; the record at its source may have been updated since.
Is CVE-2026-86102 actively exploited?
CVE-2026-86102 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 2.3% probability of exploitation in the next 30 days (82nd percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-86102?
CVE-2026-86102 has a CVSS base score of 9.3 (a secondary CVSS source that NVD displays; NVD's own analysis pending).
How do I remediate CVE-2026-86102?
No fix for CVE-2026-86102 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 (WatchGuard Technologies, Inc.) lists WatchGuard AP versions 1.0 up to but not including 3.4.8 as affected. No release containing a fix is confirmed on record. The vendor advisories EchelonGraph has for CVE-2026-86102 are linked in the Vendor Advisories panel on this page.
