- The root cause is described in b4f1988a35
- Move to a fork of `github.com/gliderlabs/ssh` that exposes the
permissions that was chosen by `x/crypto/ssh` after succesfully
authenticating, this is the recommended mitigation by the Golang
security team. The fork exposes this, since `gliderlabs/ssh` instead
relies on context values to do so, which is vulnerable to the same
attack, although partially mitigated by the fix in `x/crypto/ssh` it
would not be good practice and defense deep to rely on it.
- Existing tests covers that the functionality is preserved.
- No tests are added to ensure it fixes the described security, the
exploit relies on non-standard SSH behavior it would be too hard to
craft SSH packets to exploit this.
- A softbreak was being preserved during the github legacy callout (this
is likely due to a change in Goldmark) while it should not. This caused
an `<br>` to be present between the attention title and attention content.
- Added unit test.
This fixes a TODO in the code to validate the RedirectURIs when adding
or editing an OAuth application in user settings.
This also includes a refactor of the user settings tests to only create
the DB once per top-level test to avoid reloading fixtures.

Continuation of forgejo/forgejo#6076
## Overview
Hi all, I'm a first-time contributor to Forgejo. I was looking for something interesting to contribute and the first thing that caught my attention was https://codeberg.org/forgejo/forgejo/issues/6043, a request for an enhancement to include "issue previews" when publishing links to social media platforms. As a bit of background, the way these platforms work is that they search for meta tags in the posted link's content, and if they find a meta `og:image` (along with other meta tags) they'll pull the image to include in the social media post. Forgejo currently provides an `og:image` tag but it just renders the repository or repository-owner's avatar.
This PR will render `og:image` for an issue or PR into a link to `{...}/summary-card`, which is a dynamically generated image that contains a summary of the issue.
## Design Notes
### Rendering / Rasterization
The tricky part of solving this problem is rendering an image that combines some text, some images, and some layout elements. To address this, I've created a `card` module which allows for a handful of operations:
- Create a new rendered image (a "Card")
- Add a margin to a card
- Split the card, horizontally or vertically, into two pieces with a proportional layout (eg. 70%/30%, as desired), each of which are "Cards" that render into the same root image
- Render text into a card, with line-wrapping and text-alignment capabilities
- Render an image onto a card
- Fetches an external image as safely as possible (for server-side fetch of Gravatar, etc.)
The card module can be reused to create `og:image` summary cards for any object in the future, although obviously it's capabilities are limited. The current implementation is on issues/PRs.
I considered a few alternative approaches before taking this approach, and here's why I rejected those options:
- Provide the summary card as an SVG object which could be rendered much more easily with a template file -- however, support for SVG isn't defined as positive for OpenGraph, and a quick look through some existing implementations suggest that it is not widely supported, if at all
- Rendering as HTML/CSS, or SVG, and then using an external tool to convert into a PNG (or other static) image -- this would be much nicer and easier to implement, but would require tying in some very heavy-weight dependencies
- Rendering using a more sophisticated graphics library, eg. cairo -- also would be nicer and easier to implement, but again a heavy dependency for a small functionality
As a result of the limited capabilities of the new card module, summary cards don't have icons on them (which would require SVG rasterization) or pretty status badges with colors and rounded rects. In the future if better drawing capabilities were added, the graphics could be improved, but it doesn't seem too important.
### External Avatars
In order to rasterize a user's avatar onto the summary card, it might have to be retrieved by the server from the external source (eg. Gravatar). A `fetchExternalImage` routine attempts to do this in the safest way possible to protect the server from any possible security exposure from this; (a) verifying that the content-types are acceptable, (b) ensuring that the file-size and image-size are within the safe bounds that are used for custom avatars, (c) using a very-short timeout to avoid stalling the server if an external dependency is offline.
### Caching
Summary cards are cached after rendered. This has the downside of causing updates to statuses, avatars, titles, etc. being stale on the summary card for the cache TTL. However, during testing I found that some social media engines like Mastodon will cause the summary card to be accessed a significant number of times after being referenced by a post, causing a mini-tornado of requests. The cache compensates for this to avoid server load in this situation.
### Scope
I'm considering out-of-scope:
- Summary cards on other objects (eg. repos, users) can be left for future implementation

### Tests
- I added test coverage for Go changes...
- [x] in their respective `*_test.go` for unit tests.
- [x] in the `tests/integration` directory if it involves interactions with a live Forgejo server.
- ~~I added test coverage for JavaScript changes...~~ n/a, no JS changes
- [x] ~~in `web_src/js/*.test.js` if it can be unit tested.~~
- [x] ~~in `tests/e2e/*.test.e2e.js` if it requires interactions with a live Forgejo server (see also the [developer guide for JavaScript testing](https://codeberg.org/forgejo/forgejo/src/branch/forgejo/tests/e2e/README.md#end-to-end-tests)).~~
- Manual testing
- [x] Access & attach screenshots of both an issue and a pull-request's summary card; see below
- [x] Ensure reasonable (non-crash) behavior of rendering text with glyphs outside the font -- correctly rendered as replacement unicode chars
- [x] Using a public test instance, verify that og:image behavior looks good on platforms like Mastodon and BlueSky
- [x] Bluesky: ✅
- [x] Mastodon: ✅ (Note that the summary card will be requested many times as the post is federated; either each server, or each client, will fetch it itself)
- [x] OpenGraph test site (https://www.opengraph.xyz/): ✅
- [x] Discord: Looks OK ✅; needs "twitter:card" to be set to "summary_large_image" to display the large-scale image, but (a) that's probably annoying to use, (b) probably wrong because it doesn't match Twitter Card's spec for a "photographic image", and (c) don't want to encourage/continue use of vendor-specific tag
- [x] Verify cases with user avatar missing (or autogen), and repo avatar missing (falls back to repo owner avatar)

### Documentation
- [ ] I created a pull request [to the documentation](https://codeberg.org/forgejo/docs) to explain to Forgejo users how to use this change.
- [x] I did not document these changes and I do not expect someone else to do it.
- OpenGraph capabilities are expected to work in the background without user awareness, and so there is no need for documentation to explain the capabilities for users.
### Release notes
- [ ] I do not want this change to show in the release notes.
- [x] I want the title to show in the release notes with a link to this pull request.
- [ ] I want the content of the `release-notes/<pull request number>.md` to be be used for the release notes instead of the title.

- In the case that Enry correctly recognized the language, but returns
the language name in a way that isn't recognized by enry. Although
overkill I've added a map such that new entries should be easier to add.
- Resolves#6077
- Added unit test
- Currently the TOTP secrets are stored using the `secrets` module with
as key the MD5 hash of the Secretkey, the `secrets` module uses general
bad practices. This patch migrates the secrets to use the `keying`
module (#5041) which is easier to use and use better practices to store
secrets in databases.
- Migration test added.
- Remove the Forgejo migration databases, and let the gitea migration
databases also run forgejo migration databases. This is required as the
Forgejo migration is now also touching tables that the forgejo migration
didn't create itself.
When running e2e tests on flaky networks, gravatar can cause a timeout
and test failures. Turn off, and populate avatars on e2e test suite run
to make them reliable.

Extend API MarkupOptions to contain branch path.
The `api.MarkupOptions{}` to have `BranchPath` which contains the
current branch. The `RenderMarkup` function utilizes a struct since there
are too many variables passed as arguments and that is not a good sign
for readability.
And `repo-editor.js` will contain a new form data which is `branch-path`
which will then be utilized by `edit.tmpl` as `data-branch-path`.
Closes: #4510

It is possible to set a Email for a Organization. This Email is optional and only used to be displayed on the profile page. However, once you set an EMail, you can no longer remove it. This PR fixes that.
While working on the tests, I found out, that the API returns a 500 when trying to set an invalid EMail. I fixed that too. It returns a 422 now.

- Instead of having code that relied on the result being sorted (which
wasn't specified in the query and therefore not safe to assume so). Use
a map where it doesn't care if the result that we get from the database
is sorted or not.
- Added unit test.
- _Simply_ add `^$` to regexp that didn't had it yet, this avoids any
content being allowed that simply had the allowed content as a
substring.
- Fix file-preview regex to have `$` instead of `*`.
- Add a `purpose` column, this allows the `forgejo_auth_token` table to
be used by other parts of Forgejo, while still enjoying the
no-compromise architecture.
- Remove the 'roll your own crypto' time limited code functions and
migrate them to the `forgejo_auth_token` table. This migration ensures
generated codes can only be used for their purpose and ensure they are
invalidated after their usage by deleting it from the database, this
also should help making auditing of the security code easier, as we're
no longer trying to stuff a lot of data into a HMAC construction.
-Helper functions are rewritten to ensure a safe-by-design approach to
these tokens.
- Add the `forgejo_auth_token` to dbconsistency doctor and add it to the
`deleteUser` function.
- TODO: Add cron job to delete expired authorization tokens.
- Unit and integration tests added.
- When a dependency is renamed, specified via `package="actual-name"` in
Cargo.toml, this should become the name of the depedency when the
package is retrieved from the registery by cargo and the old name should
be available in the `package` field.
- The reference implementation also does this: 490e66a9d6/src/controllers/krate/publish.rs (L702-L705)
- Resolves#5936
- Unit test added.
