Routine

MEDIUM 6.8

CVE-2026-70620 is a medium-severity flaw (CVSS 6.8) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Odysseus before commit 87babb5 contains a server-side request forgery vulnerability that allows admin-privileged attackers to direct the server to probe internal network resources by supplying arbitrary URLs to the embedding endpoint configuration without scheme, host, IP range, or DNS rebind validation. Attackers can submit loopback addresses, RFC 1918 ranges, or link-local addresses through the embedding endpoint API to partially read responses

Why this priority

CISA SSVC: public proof of concept

A fixed release or distro patch exists.
