To prevent client-side XSS in the chat feature, any data that may originate from a user (such as username and message) must be safely encoded or inserted in the DOM in a way that doesn't interpret it as HTML. The best way to do this in vanilla JavaScript is to use textContent instead of innerHTML for user-derived values. This way, tags and special characters are displayed literally. To maintain the original design (including the "(Teacher)" distinction and : after the sender), structure the chat message element by creating and appending child span nodes with textContent set, instead of populating with a string of HTML.
Steps:
- In
addChatMessage, remove the construction of the message using a template literal forinnerHTML. - Create
spanelements for the sender and message, setting theirtextContentappropriately. - If you want to append "(Teacher)" after the username, set that string literally, not through
innerHTML. - Append all spans to
messageElement. - No new library is needed; use standard DOM APIs.
- Only edit the relevant region in
web/static/js/mass_class/student_view.js.

To fix the problem, user-supplied data must not be placed into HTML through .innerHTML without being properly escaped. The best fix is to place untrusted text as plain text nodes, either by using .textContent, document.createTextNode, or by building the node structure with text nodes rather than HTML strings.
For the affected region in addMyQuestion, instead of assembling the question HTML using .innerHTML with ${questionText}, we'll build the elements explicitly: create the outer div, then the question-text div, and set its .textContent to questionText. This guarantees special characters are interpreted as plain text, preventing XSS, while preserving visual and functional correctness.
Only modify the lines that assign .innerHTML in addMyQuestion. Leave unrelated functionality unchanged. No external libraries are necessary.

To fix this DOM-based XSS vulnerability, user-provided data must be safely injected into the DOM. Since the dangerous usage is in line 190, where innerHTML with a user-influenced string is set, the best solution is to avoid including unsanitized values in any HTML context.
The recommended pattern is:
- Use
textContentto assign all dynamic user-influenced contents to nodes, so that no parsing of HTML occurs. - Construct the DOM elements programmatically with
document.createElement, and set their attributes/text accordingly.
For this file and block: - Instead of building HTML with string interpolation and setting
optionElement.innerHTML = ..., create the input, label, and span elements usingcreateElement, assign properties (including settingtextContentfor the option text), and compose the DOM tree. - No new libraries are strictly necessary, only changes to the code in the file shown.
No other lines outside this shown region need to be changed.

To prevent DOM-based cross-site scripting, user-supplied data must not be interpolated directly into HTML via innerHTML without appropriate escaping. For poll results, the fix is to ensure that result.text (the poll option string) is not injected into the DOM as HTML. The best-practice, and in this case the safest and most direct fix, is to set the poll option text as the textContent of a DOM node, rather than interpolating it as HTML.
- Replace usage of
innerHTML = `...${result.text}...`with code that constructs the result DOM structure using element creation andtextContent/appendChildfor user data. - In
updatePollResults, instead of building one string of HTML to inject, create thediv.poll-option-textelement, set itstextContenttoresult.text, and append it to thepoll-resultitem. - Only use
innerHTMLfor static, trusted HTML (never for user content). - The same applies for displaying vote counts, but as those are numbers, they are safe;
result.textis the only user-controlled string.
What to change:
- In
web/static/js/mass_class/student_view.js, lines 241–247:
Replace the interpolated HTML string andinnerHTMLwith DOM node creation, settingtextContentforresult.text.
No new imports are needed (standard DOM methods are sufficient).

How to fix the problem:
Avoid interpolating untrusted user input (message and username) as HTML. Construct DOM elements and set .textContent/.innerText, not .innerHTML. Alternatively, sanitize input, but the preferred solution is to directly insert text.
Detailed fix:
Edit the addChatMessage function so it does not build the messageElement's content using .innerHTML and template literals. Instead:
- Create the necessary element structure with
createElement. - Fill in text fields (sender/username and message) using
.textContentrather than injecting HTML. - Only set
className/attributes via DOM properties.
Lines to change:
In file web/static/js/mass_class/teacher_broadcast.js, lines 261–271; specifically, replace the body of addChatMessage to construct child nodes in the DOM, not via innerHTML.
What's needed:
No new imports or utilities are needed—just basic DOM manipulation. Apply the fix only to the relevant section.

To fix this issue, we must ensure that user-controlled values (username and message) are not interpreted as HTML when inserted into the DOM. The best general solution is to use safe DOM methods that treat strings as plain text rather than HTML: i.e., use textContent or innerText (not innerHTML).
Specifically:
- Instead of rendering the entire message as a template string and assigning to
innerHTML, create the container node, then create the inner spans, assign their.textContentproperties directly from the input, and append the spans to the node. - This preserves all current rendering and functionality, but ensures even if malicious text is submitted, it is displayed as text, not executed.
- Edit only the
addChatMessagefunction (lines 261–271).

The vulnerability is caused by unescaped user input being injected into innerHTML. To fix this, do not use innerHTML for directly inserting tainted data. Instead, create the DOM structure using the DOM API so that user-provided text is added with textContent, which securely escapes special characters and prevents HTML/script injection. Specifically, build the poll result row element using document.createElement and assign the user option text to a .textContent property, then append all children appropriately. This preserves the intended layout and functionality—visually displaying poll options and results—while preventing XSS.
Edits required:
- Refactor the block within
options.forEachinsidecreatePoll()(lines 320-332) to build the DOM with trusted means. - Remove use of
resultElement.innerHTML = ...and instead assemble the poll result row using element creation and.textContentfor untrusted strings.
No imports or new definitions are needed beyond the standard DOM methods.

To fix this vulnerability, contextually escape or sanitize any user-controlled data before inserting it into the DOM when using innerHTML. The best approach here, without changing functionality, is to HTML-escape (encode) username and question before interpolation into the template. This prevents script injection via HTML special characters.
One robust, widely accepted method is to use an established escaping library (e.g., he) or manually encode the minimal required HTML entities (&, <, >, ", '). Since we cannot assume other files can be changed and to minimize impact, we can add a simple local escaping utility function near the affected code.
Steps:
- Add a function in this file to perform HTML entity escaping.
- Escape
usernameandquestionbefore inserting into theinnerHTMLtemplate inaddQuestion.

Missing handling for 'dismiss_question' message type. The frontend sends this event type but the consumer doesn't handle it, which will result in ignored dismiss actions.

Incorrect field name used in lookup. The model uses 'stream_id' field but the view is looking up by 'session_id'. This will cause a FieldError.

Inconsistent field reference. The model should use 'stream_id' consistently, but this references 'session_id' which doesn't exist in the MassClassViewer model.

@copilot we would let the teacher use their own stream so change how the key is stored |
- Add youtube_stream_key field to Profile model - Update _get_youtube_key to retrieve key from teacher's profile - Remove global YOUTUBE_STREAM_KEY from settings (no longer needed) - Create migration 0064 for new youtube_stream_key field - Update .env.sample to reflect that stream keys are now per-teacher Co-authored-by: A1L13N <193832434+A1L13N@users.noreply.github.com>
Updated to use per-teacher YouTube stream keys (492218e):
Teachers will need to add their YouTube Live stream key to their profile before they can broadcast. |
