CVE-2026-55787

Flyto2 Core is an execution kernel for automation and AI-agent workflows. Prior to 2.26.3, validateurlssrf and isprivateip 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...

CVE-2026-55786

Flyto2 Core is vulnerable to unauthenticated OS command injection via the HTTP MCP endpoint (POST /mcp) in versions 2.26.2 through 2.26.4 . The root cause is that the mcp_router is mounted without the require_auth dependency used by REST routes, allowing unauthenticated JSON-RPC tools/call reques...

CVE-2026-55787

The flyto-core execution kernel is vulnerable to Server-Side Request Forgery (SSRF) in versions prior to 2.26.3 due to an incomplete SSRF guard in src/core/utils.py. The validate_url_ssrf and is_private_ip functions fail to unwrap IPv6 transition addresses (such as IPv4-mapped , 6to4 , and NAT64 ...

CVE-2026-55787 Flyto2 Core: SSRF guard bypass via IPv6 transition addresses (IPv4-mapped / 6to4 / NAT64) in validate_url_ssrf

Flyto2 Core is an execution kernel for automation and AI-agent workflows. Prior to 2.26.3, validateurlssrf and isprivateip 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...

CVE-2026-73530

Flyto2 Core before 2.28.0 contains a server-side request forgery guard bypass vulnerability that allows attackers to reach internal services by supplying URLs using the unblocked IPv6 address :: which the kernel routes to loopback identically to 0.0.0.0. Attackers can submit requests or trigger 3...

CVE-2026-73530 Flyto2 Core < 2.28.0 SSRF Guard Bypass via is_private_ip()

Flyto2 Core before 2.28.0 contains a server-side request forgery guard bypass vulnerability that allows attackers to reach internal services by supplying URLs using the unblocked IPv6 address :: which the kernel routes to loopback identically to 0.0.0.0.

CVE-2026-73530

The CVE concerns Flyto2 Core prior to 2.28.0, where SSRF guard bypass is possible via unblocked IPv6 address :: that kernels treat as loopback akin to 0.0.0.0. Attackers can cause requests or 302 redirects through http.get, http.request, and http.batch to reach services bound to IPv6 loopback, by...

PYSEC-2026-3568 Flyto2 Core: Arbitrary file write via image.download (and other file-writing modules)

Summary image.download fetches a URL and writes the response to disk. It does not use the central path guard validatepathwithenvconfig, which confines writes to FLYTOSANDBOXDIR; instead it confines the output to outputdir, but outputdir is itself a caller parameter. Since the attacker sets both t...

PYSEC-2026-3570 Flyto2 Core: ${env.VAR} interpolation reads any env secret despite env.get being denylisted

Summary The capability policy denies the env.get and env.loaddotenv modules by default, with the stated reason that they read arbitrary host environment variables API keys, DSNs and are a secret-exfil risk. But the workflow engine's variable resolver expands $env.VAR for any environment variable...

CVE-2026-67429

Flyto2 Core is an execution kernel for automation and AI-agent workflows. Prior to 2.26.6, image.download and related file-writing modules use caller-controlled outputdir instead of validatepathwithenvconfig and its FLYTOSANDBOXDIR confinement, allowing attacker-controlled response bytes to be...
