The CVE record's description, written by its CNA (VulDB), states the affected versions: "A vulnerability was detected in aircheng-org iWebShop-5 up to 5.15." No release containing a fix is confirmed on record.

A vulnerability was detected in aircheng-org iWebShop-5 up to 5.15. This affects the function Login of the file controllers/systemseller.php. Performing a manipulation of the argument Name results in improper authentication. It is possible to initiate the attack remotely. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet.

EG Risk 64/100

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).

Exploitation public PoC (CISA Vulnrichment) · Automatable yes (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 8× in last 7d / 35× 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.

Showing the most recent 100 of 174 rows 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 74 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

Frequently asked(5)

What is CVE-2026-86669?
CVE-2026-86669 is a high-severity vulnerability; its CVE record was published on September 8, 2026. A vulnerability was detected in aircheng-org iWebShop-5 up to 5.15. This affects the function Login of the file controllers/systemseller.php. Performing a manipulation of the argument Name results in improper authentication. It is possible to initiate the attack remotely. The exploit is now public…
When was the CVE record for CVE-2026-86669 published?
The CVE record for CVE-2026-86669 was published on September 8, 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 8, 2026; the record at its source may have been updated since.
Is CVE-2026-86669 actively exploited?
CVE-2026-86669 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.7% probability of exploitation in the next 30 days (53rd percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-86669?
CVE-2026-86669 has a CVSS base score of 7.3 (a secondary CVSS source that NVD displays; NVD's own analysis pending).
How do I remediate CVE-2026-86669?
No fix for CVE-2026-86669 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 description, written by its CNA (VulDB), states the affected versions: "A vulnerability was detected in aircheng-org iWebShop-5 up to 5.15." No release containing a fix is confirmed on record. The vendor advisories EchelonGraph has for CVE-2026-86669 are linked in the Vendor Advisories panel on this page.
