This clarifies that the parameter sets CSP 'frame-ancestors'
to limit hosts allowed to embed comments. The commit also improves
the documentation on how to use ALLOWED_HOSTS with AUTH_SAME_SITE
for different setup scenarios.
We might want to change AUTH_SAME_SITE to `strong` in v2.0 as it works
on the subdomain of the same site as well as current Lax option.
Change the default img-src value to "*" and sets it to "'self'" when
image proxy is enabled. The previous state was inversion of this logic
which was wrong.
`Content-Security-Policy` now restricts resource loading and execution
to enhance security:
- `default-src 'none'`: Disallow all resource loading by default.
- `base-uri 'none'`: Prevents the use of `<base>` tag to change the
base URL for relative URLs.
- `form-action 'none'`: Disallows form submissions.
- `connect-src 'self'`: Restricts the origins that can be connected to
(via XHR, WebSockets, etc.) to the same origin.
- `frame-src 'self'`: Restricts the origins that can be embedded using
`<frame>` and `<iframe>` to the same origin (for `/web/` demo
endpoint).
- `frame-ancestors %s;`: Specifies the origins that are allowed to
embed this content in a frame. If no specific origins are allowed, it
defaults to `*` (any origin). This enhances security by controlling
which sites can embed your content.
- `img-src 'self'`: Allows images to be loaded only from the same
origin. If `imageProxyEnabled` is true, allows images from any origin
(`*`).
- `script-src 'self' 'unsafe-inline'`: Allows scripts to be loaded and
executed only from the same origin and allows inline scripts.
- `style-src 'self' 'unsafe-inline'`: Allows styles to be loaded and
applied only from the same origin and allows inline styles.
- `font-src data:`: Allows fonts to be loaded from data URIs.
- `object-src 'none'`: Disallows the use of `<object>`, `<embed>`, and
`<applet>` tags.
`Permissions-Policy` now restricts the use of certain browser features
which we don't use to enhance user privacy and security:
- `accelerometer=()`: Disables the use of the accelerometer sensor.
- `autoplay=()`: Disables automatic playback of media.
- `camera=()`: Disables the use of the camera.
- `cross-origin-isolated=()`: Disallows the page from being treated as
cross-origin isolated.
- `display-capture=()`: Disables the ability to capture the display.
- `encrypted-media=()`: Disables the use of Encrypted Media Extensions
.
- `fullscreen=()`: Disables the ability to use fullscreen mode.
- `geolocation=()`: Disables the use of geolocation.
- `gyroscope=()`: Disables the use of the gyroscope sensor.
- `keyboard-map=()`: Disables the use of the keyboard map.
- `magnetometer=()`: Disables the use of the magnetometer sensor.
- `microphone=()`: Disables the use of the microphone.
- `midi=()`: Disables the use of the MIDI API.
- `payment=()`: Disables the Payment Request API.
- `picture-in-picture=()`: Disables the use of Picture-in-Picture mode
.
- `publickey-credentials-get=()`: Disables the use of the Web
Authentication API.
- `screen-wake-lock=()`: Disables the ability to prevent the screen
from dimming.
- `sync-xhr=()`: Disables synchronous XMLHttpRequest.
- `usb=()`: Disables the use of the USB API.
- `xr-spatial-tracking=()`: Disables the use of spatial tracking in
WebXR.
- `clipboard-read=()`: Disables the ability to read from the clipboard
.
- `clipboard-write=()`: Disables the ability to write to the clipboard
.
- `gamepad=()`: Disables the use of the Gamepad API.
- `hid=()`: Disables the use of the Human Interface Device API.
- `idle-detection=()`: Disables the ability to detect idle state.
- `interest-cohort=()`: Disables the use of interest cohort tracking.
- `serial=()`: Disables the use of the Serial API.
- `unload=()`: Disables the ability to use the `beforeunload` and
`unload` events.
- `window-management=()`: Disables the ability to use window
management APIs.
MakeTree calculated Info locally for historical reasons,
and the results were consistent with the dataService.Info call
but calculated differently.
That change fixes that, ensuring that Info is requested
in the same manner.
Previously, the error printed was just the following:
error response "401 Unauthorized", Unauthorized"
New error:
error response "401 Unauthorized", ensure you have set ADMIN_PASSWD
and provided it to the command you're running: Unauthorized
Previously, status 200 was set for file export, which is used
for backup, which resulted in an inability to set an error status code
in case of a problem with file generation.
After this change, status code 200 would be written automatically by Go
before we start writing the response's body.
Previously, images were deleted only from comments deleted
before EditDuration expiration. After this change, any deletion
of the comment deletes images if they are not used elsewhere
in comments under the same page.
Previously, top-level comments were incorrectly assigned
parent comment id "root", which made them non-root,
so they are not returned when requested
in the `/find?format=tree` API call.
To fix the previously imported comments, please export all your comments
and replace `"pid":"root"` with `"pid":""` and then re-import them.
Previously, only the first one was returned for site-wide requests,
and now all returned information will be correctly aggregated,
and the PostInfo.URL and PostInfo.ReadOnly parameters will be dropped.
Allowed domains consist of `REMARK_URL` second-level domain (or whole IP in case it's IP like `127.0.0.1`) and `ALLOWED_HOSTS`. That is needed to prevent Remark42 from asking arbitrary servers and storing the page title as the comment.PostTitle.
Previous behaviour allowed the caller of the API to create a comment
with an arbitrary URL and learn the title of the page, which might be
accessible to the server Remark42 is installed on but not to the user
outside that network (CWE-918).

Previously, we stripped unsafe HTML tags but left some,
but it's not expected to have a link in a title or username,
so the new behaviour is stripping everything.
Previously, proxied and local images were checked for presence in the
storage before previewing or posting the comment. That logic resulted in
an inability to post with an image when a proxy for images is enabled,
as proxied images are not downloaded to disk before the first time
someone loads them, which could only happen after the user either
previews or posts the message.
After this change, preview and post only checks the local images'
presence and ignore the proxied ones.
1) Current implementation simply removes the last word, without truncating up to limit length.
2) In case if even the first word (magnet link or some base64?) is too long don't add extra space.
(url) is a text inserted by default and never an intended URL.
That additional validation will ensure that users won't post relative
links because they are rarely intended.
Without this option, the aud is ignored.
It works only with RPC admin storage.
The shared key returned for all requests with the default shared admin
storage, so enabling that option does not affect it.
