The CVE record's CNA (Progress Software Corporation) lists Progress ShareFile Storage Zones Controller versions up to and including 5.12.3 as affected. No release containing a fix is confirmed on record.

Customer Managed ShareFile Storage Zones Controller (SZC) allows an unauthenticated attacker to access restricted configuration pages. This leads to changing system configuration and potential remote code execution.

EG Risk 85/100

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 13× in last 7d / 60× 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 332 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 232 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

Publicly available exploits

(2 references)

Public exploit code is referenced for this CVE (1 GitHub PoC), as is 1 Nuclei detection template. A detection template checks whether a system is affected; it is not necessarily exploit code. No fix is confirmed yet, so defenders should restrict or isolate affected systems accordingly until one is published.

Frequently asked(5)

What is CVE-2026-2699?
CVE-2026-2699 is a critical-severity vulnerability; its CVE record was published on April 2, 2026. Customer Managed ShareFile Storage Zones Controller (SZC) allows an unauthenticated attacker to access restricted configuration pages. This leads to changing system configuration and potential remote code execution.
When was the CVE record for CVE-2026-2699 published?
The CVE record for CVE-2026-2699 was published on April 2, 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 October 26, 2026; the record at its source may have been updated since.
Is CVE-2026-2699 actively exploited?
CVE-2026-2699 is not currently on CISA's Known Exploited Vulnerabilities catalog. EchelonGraph's EG-KEV model places it in Tier 2 (Weaponized), which is not evidence of exploitation: CISA's SSVC data says a public PoC exists and its EPSS is 50% or more. EchelonGraph does not test whether exploit code works. FIRST EPSS estimates a 58% probability of exploitation in the next 30 days (99th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2026-2699?
CVE-2026-2699 has a CVSS v3 base score of 9.8 (NVD).
How do I remediate CVE-2026-2699?
No fix for CVE-2026-2699 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 (Progress Software Corporation) lists Progress ShareFile Storage Zones Controller versions up to and including 5.12.3 as affected. No release containing a fix is confirmed on record.
