49e4e55d2c fix(skills): harden skill import against DNS rebinding and SSRF TOCTOU (#5986)
* fix(skill-importer): validate URL scheme and improve skills.sh handling

* fix(skill-importer): enhance DNS resolution and SSRF protection in fetch URL handling

* fix(url-safety): add allowed_dist parameter to check_outbound_url for flexible private blocking

* test(skill-importer): add comprehensive tests for URL parsing and outbound checks

* ensure newline at end of file in test_check_outbound_url_allows_public_ip

* fix(skill-importer): improve TLS certificate handling in _get_checked function

* fix(skill-importer): enhance _check_fetch_url to handle both hostnames and full URLs

* fix(skill-importer): enhance parse_skill_source to support skills.sh URLs in path and netloc

* fix(skill-importer): simplify skills.sh hostname check in parse_skill_source

* fix(skill-importer): enhance parse_skill_source to identify skills.sh URLs in path and handle localhost/IP addresses

* fix(skill-importer): enhance _resolve_and_check_url to validate all resolved IP addresses and prevent TOCTOU vulnerabilities

* fix(skill-importer): enhance parse_skill_source to support schemeless GitHub and skills.sh URLs

* fix(memory): resolve CodeQL URL sanitization warning and restore _check_fetch_url test alias

* fix(memory): pin skill fetch sockets without rewriting URLs

* fix(memory): reject unsupported skill wrapper hosts

* refactor(url-safety): remove unused importer exception

* test(memory): keep redirect regression hermetic

* test(dns-rebinding): add test for _PinnedTransport to ensure connection to pinned IP

* fix(skill-importer): enhance skills.sh support to extract GitHub links from page content

* fix(skill-importer): improve URL scheme validation for GitHub and skills.sh links

* fix(skills): reject unusable skill URLs instead of guessing

Resolving a skills.sh link by scraping the first github.com URL out of
the page body cannot work. Skill pages only ever link the repository
root, never the skill's subdirectory, so every skill in a repo resolved
to the same bundle: importing skills.sh/anthropics/skills/pdf walked the
whole monorepo, saturated the 64-file cap, and installed algorithmic-art
behind an ok:true response. Restore the redirect-target unwrap and fail
with a message that says what to do instead.

Also report the real reason a URL is rejected. The scheme check keyed off
"://" appearing anywhere in the string, so a supplied-but-unusable URL
came back as "URL is required", and a schemeless URL carrying "://" in
its query was reported as an unsupported scheme. Key off the parsed
scheme and let opaque schemes (mailto:, javascript:) and a schemeless
host:port fall through to the host check.

* test(skills): tighten the real-socket pinning regression

The handler swallowed its own exceptions, so a failure inside it
surfaced as a confusing assertion on the captured client address.
Record the exception and assert on it, run the thread as a daemon, and
close the listening socket from the test so a hang cannot outlive the
run. Also drop the duplicate ipaddress import and the missing newline.

* fix(skills): require exact GitHub skill URLs

* test(skills): read complete pinned request headers

Packaging status

Odysseus interface


Quick Start

dev is the default branch and gets the newest changes first. Use main if you want the more curated branch.

git clone https://github.com/odysseus-dev/odysseus.git
cd odysseus
cp .env.example .env
docker compose up -d --build

Open http://localhost:7000 when the containers are healthy. The first admin password is printed in docker compose logs odysseus.

Native installs, GPU notes, Windows/macOS instructions, HTTPS, and configuration live in the setup guide.

Features

  • Chat + Agents — local/API models, tools, MCP, files, shell, skills, and memory.
  • Cookbook — hardware-aware model recommendations, downloads, and serving.
  • Deep Research — multi-step web research with source reading and report generation.
  • Compare — blind side-by-side model testing and synthesis.
  • Documents — writing-first editor with AI edits, suggestions, Markdown, HTML, CSV, and syntax highlighting.
  • Email — IMAP/SMTP inbox with triage, tags, summaries, reminders, and reply drafts.
  • Notes, Tasks + Calendar — reminders, todos, scheduled agent tasks, and CalDAV sync.
  • Extras — gallery/image editor, themes, uploads, web search, presets, sessions, and 2FA.

Demo

A full hover-to-play tour lives on the landing page: docs/index.html.

Contributing

Help is welcome. The best entry points are fresh-install testing, provider setup bugs, mobile/editor polish, docs, and small focused refactors. See CONTRIBUTING.md and ROADMAP.md.

Security

Odysseus is a self-hosted workspace with powerful local tools. Keep auth enabled, keep private data out of Git, and do not expose raw model/service ports publicly. Deployment details are in the setup guide.
