SCA: security update for flyto-core (GHSA-794r-5rp2-fpg8)

high Tenable Self-Hosted Container Security Plugin ID 444417

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Flyto2 Core is an execution kernel for automation and AI-agent workflows. Prior to 2.26.3,
 validate_url_ssrf and is_private_ip in src/core/utils.py compare resolved addresses only against native
 private IPv4 and IPv6 ranges and do not unwrap IPv4-mapped, IPv4-compatible, 6to4, or NAT64 transition
 addresses. An authenticated workflow author can provide a transition-form literal URL through the
 Execution API POST /v1/execute route, http.get, or sibling guarded outbound-request modules, causing the
 guard to accept an address whose embedded IPv4 points to loopback, RFC 1918, or cloud metadata services.
 On a host that routes the selected transition form, the outbound request reaches the internal destination
 and returns the response body to the workflow caller, enabling read SSRF and disclosure of internal-
 service data or cloud credentials. This issue is fixed in version 2.26.3. (CVE-2026-55787)

Solution

Update the flyto-core library and its related packages to version 2.26.3 or later.
