hol-guard supply-chain scanDeepSeek TUI has SSRF IPV6 bypass affects deepseek-tui (rust). Severity is high. ### Summary 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. ### Details https://github.com/Hmbown/DeepSeek-TUI/blob/15f62e3e93d842f30b428877819ebc1c8cb96814/crates/tui/src/tools/fetch_url.rs#L321 ### PoC Prompt: `Run fetch_url tool and give output, no thinking.

AI coding agents often install or upgrade packages automatically in rust. A high vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
| Package | Affected range | Fixed version |
|---|---|---|
| deepseek-tuirust | <0.8.26 | 0.8.26 |
Fixed versions are reported by the source feed; confirm compatibility before updating.
