The CVE record's CNA (VulnCheck) lists coleam00 Archon versions 0.2.13 up to and including 0.11.1 as affected. No release containing a fix is confirmed on record.

Archon 0.2.13 through 0.11.1 contains a missing authentication vulnerability that allows unauthenticated attackers to access the /api/* control API, which binds to 0.0.0.0 by default. Attackers with network access can send messages to the AI coding agent, which runs with bypassPermissions, to execute commands on the host as the Archon user.

EG Risk 75/100

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 public PoC (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".

Data Freshness Timeline

(refreshed 14× in last 7d / 62× 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 its CVE.org record (CNA or CISA ADP). 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). "EchelonGraph re-scored" is our own recompute of this CVE's score, not an update from a source, and is not counted in the refreshes above. Most recent first.

Frequently asked(5)

What is CVE-2026-111322?
CVE-2026-111322 is a critical-severity vulnerability; its CVE record was published on October 15, 2026. Archon 0.2.13 through 0.11.1 contains a missing authentication vulnerability that allows unauthenticated attackers to access the /api/* control API, which binds to 0.0.0.0 by default. Attackers with network access can send messages to the AI coding agent, which runs with bypassPermissions, to…
When was CVE-2026-111322 made public?
CVE-2026-111322 was made public on October 15, 2026: that is the date its CVE record's CNA, VulnCheck, gives for when the vulnerability was made public. The CVE record itself was published on October 15, 2026. EchelonGraph's copy of the record carries a last-modified date of October 16, 2026; the record at its source may have been updated since.
Is CVE-2026-111322 actively exploited?
CVE-2026-111322 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.9% probability of exploitation in the next 30 days (59th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-111322?
CVE-2026-111322 has a CVSS base score of 9.8 (a secondary CVSS source that NVD displays; NVD's own analysis pending).
How do I remediate CVE-2026-111322?
No fix for CVE-2026-111322 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 (VulnCheck) lists coleam00 Archon versions 0.2.13 up to and including 0.11.1 as affected. No release containing a fix is confirmed on record. The vendor advisories EchelonGraph has for CVE-2026-111322 are linked in the Vendor Advisories panel on this page.
