- A redirect followed for a custom base URL also drops the key headers of
providers that do not use Authorization (x-api-key, x-goog-api-key,
api-key) when it goes to another origin.
- A second Enter or click while a message is being prepared (attachments
read, diagram exported) no longer sends it twice.
- The admin Test on the deployment's own endpoints (EdgeOne, the server's
keyless Ollama, an address on the server's network) counts toward the
quota like a chat; the chat and the Test share one rule for it. The
Test of an Azure entry set up by AZURE_RESOURCE_NAME only goes where chat
goes.
- EdgeOne's function is called at the site root again, as on main: EdgeOne
serves edge functions there, outside Next's base path.
- MCP History: the state before a write is kept unless the browser saved
no change of the user's since the last server write (draw.io's sync copy
of it adds no entry), and the dedupe compares the exact text again, so a
change of page size or other settings only is its own version.
- MCP: an edit keeps untouched labels as draw.io shows them (a literal line
break in an attribute is a space); a new document of empty pages the
user named is auto-saved; load_diagram reads only regular files, so a
pipe cannot hold up the other write tools; the preview does not load
back its own push still on its way (an undo made meanwhile is saved).
- Two overlapping saves of a new chat no longer reload the canvas from the
older copy.
- At most three screenshot checks per user turn, passed or failed, as
documented.
- Desktop: the main window navigates only within the app (draw.io stays in
its frame); a presets file that is not JSON and cannot be moved aside is
not overwritten.
- A last self-closing cell with a raw "<" in a value is not taken for cut
off output.
- README: Material Design shapes load their icons from fonts.gstatic.com.
- A redirect followed for a custom base URL (quota on) no longer carries
the user's key or cookies to another origin, as fetch itself does, and
a private address may redirect to another private one (already counted).
- The admin Test of an Ollama or Vertex AI entry without a URL goes where
chat sends that entry's key: the environment's own URL variable, for
Ollama else the local default. The Test of an Ollama Cloud key without
a URL went to the cloud while chat went to local Ollama.
- Chat saves: each save notes the chat on screen and the order of the
reads before reading its data. A save read before switching chats no
longer writes into the chat switched to, and a copy that waited for its
thumbnail no longer replaces a newer one.
- "Continue without saving" keeps its button when a later auto-save fails,
and goes away when a new message is sent.
- A screenshot check that was waiting for its image when the user pressed
Stop stays skipped after the next message.
- MCP History: draw.io's own copy of a diagram (after get_diagram) no
longer adds an entry without a picture; a change of background is still
its own version. The tab ignores an edit's answer that arrives after a
newer AI write loaded.
- Desktop: a deleted preset is not brought back by a failed switch, and a
request naming no preset does not stop a rollback. An origin keeping
an access code counts as having settings.
- .env: a quoted value ending in a backslash ("C:\dir\") is read as dotenv
reads it.
- The tool card no longer crashes on an id that does not turn into text;
an older Test's success timer no longer ends a newer Test's spinner.
- Tests that passed without their fix now check it.
Chats:
- New Chat right after an answer saves that chat once. Saves run one at
a time and read the chat on screen when their turn comes; a save
scheduled for a chat that is no longer on screen is dropped. A chat
whose id was still on its way to the URL no longer comes back after
New Chat (the next answer went into it).
- Crossing the 768 px breakpoint keeps the chat panel: a streaming answer,
unsaved messages and attachments stay. The panel gets the sizes of each
side, and a panel collapsed on desktop opens on mobile.
- The chat's export waits for its own reply: an edit's history export
still on its way no longer answers it with the older diagram, and two
file saves at once no longer swap results.
- A second edit in one answer is previewed on the first edit's result.
- Stop also ends a running screenshot check; a chat that cannot be saved
(storage full) can be left with "Continue without saving".
- Small diagrams with shapes count as diagrams; the tool card no longer
crashes on malformed operations.
Quota and providers:
- Requests that reach the server's own endpoints count toward the quota:
EdgeOne (always its own endpoint now), a private base URL whatever key
header is sent, keyless Ollama without a URL. With the quota on, a
redirect is followed only to a public address. The output cap applies
to these requests too.
- Stop records the tokens of the steps that finished; the screenshot check
counts its tokens without counting a request.
- EdgeOne configured only by AI_PROVIDER works, also in the admin Test,
which forwards the access code. Azure set up only in the admin panel
works in chat. The Test sends a Bedrock session token.
- The admin panel's Test of an entry without a URL uses the server's URL
as the server does (no private address check for it); the admin panel
no longer writes an Ollama URL.
MCP server:
- Write tools and start_session run one at a time, so two at once never
drop each other's change; a cancelled call waiting its turn is skipped.
get_diagram and export_diagram keep the session they started with.
- Export to .drawio first gets the user's latest edits from the browser.
- History thumbnails: one that arrives after the next AI write is
dropped; a sync reply keeps the image; a version that changed only page
settings is its own entry.
- A diagram over the 10 MB limit is saved without its image, or the user
is told to download it (the server now answers 413 instead of cutting
the connection).
- Labels holding text like id='1' or parent='1' are no longer read as
attributes (a layer or a parent was deleted). A broken bare
<mxGraphModel> file is refused.
- After a sync reply the tab no longer sends its autosave copy again.
Desktop and files:
- A newer switch of the same preset is not rolled back by an older one
that failed. .env values with escaped quotes are read whole.
- MCP saved files: a file that could not be read stays protected while a
folder without permission hides it, and is saved again once deleted.
- The desktop app reports "no chats" only when the count was read and no
model settings are stored.
* fix: resolve DNS before SSRF check and block redirects in parse-url
isPrivateUrl() did string-only hostname matching and never resolved DNS,
so a public-looking name that maps to an internal IP (e.g.
127-0-0-1.sslip.io -> 127.0.0.1) passed the check while fetch/extract
later resolved it and reached internal services (GHSA-wqcv-5qvx-vx75).
- isPrivateUrl is now async: it keeps the fast string/literal-IP path,
then resolves the hostname via DNS and rejects if any address is private.
- parse-url now fetches the page itself with redirect: "error" and parses
via extractFromHtml(), since article-extractor follows redirects
internally and drops a redirect option, which allowed a public URL to
302 to an internal host.
- Update validate-model call site to await; add regression tests.
* fix: preserve charset detection and block CGNAT range in parse-url SSRF fix
Follow-up to the multi-reviewer review of the SSRF fix:
- Restore charset handling lost when switching from extract() to
response.text(): non-UTF-8 pages (Shift_JIS/GBK/EUC/Big5, common on CJK
sites this project targets) decoded as mojibake. Now read the body as
bytes, detect charset from Content-Type / <meta charset>, and decode
with TextDecoder before extractFromHtml.
- Wrap extractFromHtml in try/catch: it throws (not returns null) on
empty/non-HTML bodies, which previously surfaced as a 500 instead of the
intended 400.
- Add 100.64.0.0/10 (RFC 6598 CGNAT) to isPrivateIp; it is routable inside
some cloud internal networks and was a residual SSRF target.
- Add tests for CGNAT, its boundaries, 0.0.0.0, and DNS-resolved IPv6.
* fix: block private IPv6 URLs
* fix: cover full fe80::/10 link-local range and :: unspecified
- Replace startsWith("fe80:") with a check covering the full fe80::/10
range (fe80 through febf) per RFC 4291.
- Add :: (unspecified) to the localhost block.
- Drop the dead 0:0:0:0:0:0:0:1 branch (URL parser normalizes it to ::1).
- Add tests for fe9f::1, febf::1, and ::.
