Recommendation: Monitor — no exploitation signal at the moment.

CodeWhale is a DeepSeek + MiMo coding agent in terminal. Prior to 0.8.26, although SSRF is validated against hostnames that resolve to private IPv6 addresses, when providing the IPV6 in‌‌ URL‌ as http://[::1], the SSRF defenses do not work. This vulnerability is fixed in 0.8.26.
