When an agent turn uses native (OpenAI-style) function calling and the model
returns only tool calls with no prose, _append_tool_results built the follow-up
assistant message with content "" (empty string).
Google Gemini's OpenAI-compatible endpoint and Ollama both reject an assistant
message that carries tool_calls alongside an empty-string content with HTTP 400.
Because that message feeds the tool results back to the model, every tool-using
turn on these providers dies at the second round: the tool runs, but the agent
never produces a result.
Use None (JSON null) instead, which is the spec-correct form the OpenAI SDK
itself emits and which OpenAI and Anthropic accept too. Adds tests covering the
native tool-call content shaping.
The DuckDuckGo HTML fallback returns redirect URLs (//duckduckgo.com/l/?uddg=...)
instead of actual page URLs. This caused fetch_webpage_content() to reject them
instantly because _public_http_url() requires an http/https scheme, making search
results unfetchable in deep research mode.
Added _resolve_url() to:
- Convert protocol-relative URLs to absolute (https:)
- Convert path-relative URLs to absolute
- Extract the real URL from DuckDuckGo's /l/?uddg= redirect parameters
A fresh `docker compose up -d` shows the searxng container failing its
healthcheck with permission errors at setup (reported in #721 — the
service comes up under names like `odysseus_searxng_1` and never goes
ready, which then blocks the main odysseus container because of the
`depends_on: searxng: condition: service_healthy` gate).
Root cause: the official `searxng/searxng:latest` image runs as the
non-root `searxng` user but its entrypoint still needs to
1. chown /etc/searxng on first boot so the persisted named volume is
owned by the searxng user inside the container,
2. su-exec to drop / re-assert privileges before launching uwsgi, and
3. let our wrapper entrypoint (which seeds settings.yml into the named
volume on first boot) write the file through the volume mount.
Without explicit `cap_add`, the container has neither CHOWN nor
DAC_OVERRIDE nor SETUID/SETGID, so the entrypoint aborts at the first
chown / su-exec / redirection with EACCES. The upstream searxng-docker
compose file solves this with the standard "drop everything, grant only
what's needed" capability pattern.
Fix: mirror the upstream cap_drop ALL / cap_add CHOWN, SETGID, SETUID,
DAC_OVERRIDE on the searxng service. This grants only the four caps the
entrypoint actually needs, matches what searxng-docker ships with, and
leaves ports, volumes, env, healthcheck, and the wrapper entrypoint
unchanged.
Closes#721.
SkillsManager.update_skill walks every SKILL.md on disk and matches by
slug only; the 'owner' key in its scalar_keys whitelist meant a caller
could pass updates={'owner': 'attacker', 'description': 'pwned'} and the
first matching file on disk got silently re-owned. Two users with the
same slug under different category directories (which is supported by
the on-disk layout <category>/<name>/SKILL.md) could each stomp the
other's skill via the manage_skills tool or the in-process callers in
tool_implementations.py (edit, patch, publish, delete).
update_skill and delete_skill now require the caller's owner and only
match a file whose parsed owner field matches. The default of None
means 'no scope' and only matches ownerless skills, so an unsafe call
without an explicit owner is now a no-op. 'owner' is also removed from
scalar_keys so the updates dict cannot be used to reassign ownership
even when the manager is called from an in-process path that didn't
supply the owner argument.
The in-process callers in tool_implementations.py are updated to pass
owner=owner (which was already in scope at every call site) so the
HTTP and agent paths both go through the scoped check. The HTTP route
at routes/skills_routes.py:1499 was already owner-scoped via
sm.load(owner=user); the fix brings the in-process path up to the
same standard.
After a successful password change, revoke all browser sessions for the
same user except the one that submitted the request. This prevents stale
sessions on other devices from remaining valid after credentials are
updated.
Keep API-token behavior unchanged. The current browser session is
preserved so the user can continue from the tab that changed the
password.
Add focused regression tests for preserving the current session, revoking
other sessions, persisting revocation, and avoiding revocation when the
current password is incorrect.
`core.middleware.require_admin` grants admin to any request whose
`request.state.current_user == "internal-tool"` — the sentinel meant only
for the in-process tool-loopback path. But the normal cookie auth path
(app.py) sets `current_user` to the raw username, and neither `create_user`
nor the signup route reserved that name. As a result an account literally
named "internal-tool" was silently treated as admin by every
`require_admin`-gated route. With self-service signup enabled this is an
anonymous -> admin privilege escalation.
Reserve the full synthetic-owner set the codebase already special-cases —
"internal-tool", "api", "demo", "system" (see `_SYNTHETIC_OWNERS` in
routes/assistant_routes.py and the matching guards in src/task_scheduler.py
and routes/research_routes.py). "api" collides with the bearer-token owner
sentinel; "demo"/"system" would leave a real account denied an assistant
and inconsistently owner-scoped.
Refuse to create or rename into any reserved name (case/space-normalized),
and reject empty usernames while we're here. Adds a regression test.

`mdToHtml` deliberately stashes literal <details> blocks and <a> tags from
the source text *before* the global HTML-escape pass and restores them
verbatim into the string callers assign to `innerHTML` (e.g. chatRenderer's
`b.innerHTML = ...processWithThinking(text)`). Nothing scrubbed those
fragments, so message/agent content containing
`<details><img src=x onerror=...></details>` or
`<a href="javascript:..." onmouseover=...>` executed arbitrary script in
the authenticated page.
Route both stashed fragments through `sanitizeAllowedHtml()`, which parses
them in an inert <template> (no resource loads, no script execution),
removes script-capable elements, and strips event-handler attributes plus
javascript:/vbscript:/data: URL schemes. Hardening details:
- Compare tag names case-insensitively and drop the SVG/MathML foreign-
content roots. An SVG-namespaced <script> has the lower-case tagName
'script', so an HTML-only upper-case check would miss it — a real bypass.
- Sanitize to a fixpoint (re-parse + re-clean until stable) to blunt
mutation-XSS, where re-serializing/re-parsing reshapes the tree.
Benign anchors and <details> blocks are preserved unchanged.
Verified under jsdom against the obvious vectors plus mutation-XSS probes
(svg/math-namespaced <script>, foreignObject, ns-confusion, comment
breakout, template smuggling): no script/iframe element, event handler, or
javascript:/data: URL survives, and benign markup is kept.

Require admin access before serving provider discovery data from
GET /api/providers. This prevents normal authenticated users from
triggering provider discovery or receiving cached provider host data.
Keep GET /api/models available to normal users and leave the existing
admin-only GET /api/discover behavior unchanged.
Add a focused regression test to ensure unauthorized callers cannot
trigger discovery and cannot receive cached provider data.
The synchronous llm_call() runs in FastAPI's threadpool (sync route
handlers such as POST /sessions/auto-sort), while llm_call_async() runs
on the event loop. Both mutate the module-level _response_cache,
_host_fails and _dead_hosts dicts, so these are touched from multiple OS
threads concurrently. Two races result:
- _set_cached_response() snapshots 64 keys then deletes them with
`del _response_cache[key]`; if another thread evicts the same key
first, the del raises KeyError mid-eviction. Switched to
pop(key, None).
- _mark_host_dead() does get()+1+set() on _host_fails with no lock, so
concurrent connect failures lose increments and a genuinely dead host
can stay under its cooldown threshold. Guarded the host-health maps
with a threading.Lock (also applied to _is_host_dead / _clear_host_dead
for consistent reads).
Adds tests/test_llm_core_concurrency.py with deterministic regression
tests (phantom snapshot key for the eviction race; a slow-read dict that
forces the lost-update window for the counter). Both fail on the
unpatched code and pass with the fix.
The email reader folds quoted history into <details> summaries via
`_foldSummary()` (static/js/emailLibrary/signatureFold.js), which builds a
sender/date "meta" chip into the summary HTML and assigns it to innerHTML.
The server-side thread parser (`_extract_quote_meta`,
src/email_thread_parser.py) strips tags but then un-escapes HTML entities
and preserves `<...>` patterns, and that raw meta reaches `_foldSummary`
unescaped via `_renderTurnsFromServer` (`t.meta`) — so an inbound email
whose quoted attribution contains `From: <img src=x onerror=...>`
runs script when the victim merely opens the message (stored XSS).
Make `_foldSummary` the single escaping chokepoint: escape `primary` and
`subMeta` with the module's existing `_esc`. The client-side
`_extractQuoteMeta` previously pre-escaped its output, and every consumer
of it routes through `_foldSummary`, so drop that now-redundant escaping to
avoid double-encoding (e.g. "Ben & Jerry" -> "Ben &amp; Jerry").
Verified (jsdom): server-raw and client-extracted malicious metas yield 0
live elements and 0 event-handler attributes; benign "Ben & Jerry" renders
single-escaped.
