Vulnerability Snapshot
CVE-2026-15704 is rated CRITICAL — exploitation is trivial or already observed in the wild and impact is severe. Patch immediately, not on the next maintenance window.
Executive Summary
In Eclipse BaSyx Go Components versions up to and including 1.0.0, ABAC-enabled deployments are vulnerable to an authorization bypass caused by inconsistent trailing-slash handling between the ABAC middleware and the HTTP router.
The shared router configuration used Chi's middleware.StripSlashes, so a request such as GET /shells/ was dispatched to the registered GET /shells route. However, the ABAC middleware evaluated the original request path including the trailing slash. If ABAC route lookup did not find a matching slash-suffixed route, the request was passed onward and the router then stripped the slash and executed the protected handler without the intended ABAC authorization decision and without the expected ABAC query filters.
An unauthenticated or unauthorized network attacker could append a trailing slash to protected API routes to reach handlers that should have been denied by ABAC policy. Depending on the exposed component, HTTP method, and deployed policy, this

Frequently Asked Questions
What is CVE-2026-15704?
CVE-2026-15704 is a critical-severity vulnerability tracked under the Common Vulnerabilities and Exposures program. In Eclipse BaSyx Go Components versions up to and including 1.0.0, ABAC-enabled deployments are vulnerable to an authorization bypass caused by inconsistent trailing-slash handling between the ABAC mi
Am I affected?
Affected technology is listed in the Affected Products section above. If your asset inventory contains any of them, assume in-scope until you can prove otherwise.
How urgent is the response?
Critical: do not wait for your normal patch cycle. Verify exposure today, apply the vendor patch immediately, and add detection rules for any post-exploit indicators.
How do I remediate?
Apply the vendor patch listed in the upstream advisory linked under Sources. If the patch is not yet available, follow the vendor-supplied workaround (often a config flag or feature disable) and add detections for the published exploit pattern in your SIEM. Re-scan after the patch lands to confirm the finding clears.
Where can I track exploitation activity?
Watch CISA's Known Exploited Vulnerabilities catalog for CVE-2026-15704. Cross-reference with public exploit databases and your own SIEM/IDS for indicator-of-compromise patterns. Vulnios tracks KEV status automatically and surfaces it on the asset findings view.
How does Vulnios help with this?
Vulnios continuously cross-references your asset inventory against the live CVE feed (NVD, vendor advisories, CISA KEV, and curated OSINT). When a new CVE matches your environment, you get a prioritized finding with the severity, KEV status, exploit-prediction (EPSS), and a direct path to the vendor patch.
