From 8900a27c40663510f5e6730d312a6d1d231fa96e Mon Sep 17 00:00:00 2001 From: Sam Valladares Date: Sun, 28 Jun 2026 16:08:53 -0500 Subject: [PATCH] fix(audit): round-2 panics, overflows, XML/SSRF hardening (swarm) Second swarm pass (complete every-line sweep), verified against real code (38/101 confirmed real; 63 false positives excluded). This commit lands the main-compatible subset: - redmine SSRF guard: rewrite host check to use host_str()+std::net::IpAddr instead of the `url` crate (url is not a direct dep of vestige-core on main; the previous form only compiled on the feature branch). Same protection: blocks localhost + loopback/private/link-local/unspecified IPs. - bin/restore: guard wrapper[0] index (empty backup array would panic) - bin/cli: char-boundary-safe node.id truncation (2 byte-slice panics); XML-escape the model/home strings before launchd plist substitution - prospective_memory: Duration::try_hours/try_days (panic on out-of-range user config); case-insensitive " at " split now uses the lowercased index so the contains() check and the split agree core 477/0, mcp builds, clippy clean.
