> [!NOTE] > This advisory was originally emailed to community@solidjs.com by @nsysean. To sum it up, the use of javascript's `.replace()` opens up to potential XSS vulnerabilities with the special replacement patterns beginning with `$`. Particularly, when the attributes of `Meta` tag from solid-meta are user-defined, attackers can utilise the special replacement patterns, either `$'` or `$\`` to achieve XSS. The solid-meta package has this issue since it uses `useAffect` and context providers, which injects the used assets in the html header. "dom-expressions" uses `.replace()` to insert the assets, which is vulnerable to the special replacement patterns listed above. This effectively means that if the attributes of an asset tag contained user-controlled data, it would be vulnerable to XSS. For instance, there might be meta tags for the open graph protocol in a user profile page, but if attackers set the user query to some payload abusing `.replace()`, then they could execute a...

Inserts/JSX expressions inside illegal inlined JSX fragments lacked escaping, allowing user input to be rendered as HTML when put directly inside JSX fragments. For instance, `?text=<svg/onload=alert(1)>` would trigger XSS here. ```js const [text] = createResource(() => { return new URL(getRequestEvent().request.url).searchParams.get("text"); }); return ( <> Text: {text()} </> ); ```

### Summary In certain Subsonic API endpoints, authentication can be bypassed by using a non-existent username combined with an empty (salted) password hash. This allows read-only access to the server’s resources, though attempts at write operations fail with a “permission denied” error. ### Details A flaw in the authentication check process allows an attacker to specify any arbitrary username that does not exist on the system, along with a salted hash of an empty password. Under these conditions, Navidrome treats the request as authenticated, granting access to various Subsonic endpoints without requiring valid credentials. ### Proof of Concept (PoC) 1. Generate a random salt: ```javascript // e.g., salt = "x1vbudn1m6d" Math.random().toString(36).substring(2, 15) ``` 2. Calculate the MD5 hash of an empty password plus the salt: ```shell # Using the example salt above echo -n "x1vbudn1m6d" | md5sum 81f0c0fb5d202ab0d012e6eaeb722d79 - ``` 3. Send a re...

### Impact Only users that has configured a JupyterHub installation to use the authenticator class `LTI13Authenticator` are influenced. LTI13Authenticator that was introduced in `jupyterhub-ltiauthenticator` 1.3.0 wasn't validating JWT signatures. This is believed to allow the LTI13Authenticator to authorize a forged request granting access to existing and new user identities. ### Patches None. ### Workarounds None. ### References - [This code segment](https://github.com/jupyterhub/ltiauthenticator/blob/3feec2e81b9d3b0ad6b58ab4226af640833039f3/ltiauthenticator/lti13/validator.py#L122-L164) didn't validate a JWT signature.
