Summary
AIL Project contains a stored cross-site scripting vulnerability in the translation controls for chat messages and forum posts. Message and post identifiers were inserted into JavaScript onclick handlers without safe encoding for string literals. A crafted identifier can inject arbitrary JavaScript into the event handler.
Risk Assessment
Risk includes execution of malicious code in the victim's browser under the security origin of the AIL instance. Requires victim to click the affected translate button.
Recommendation
Update AIL Project to a version that safely encodes identifiers as JavaScript literals in HTML attributes.

Original NVD description (English source)
AIL Project contains a stored cross-site scripting vulnerability in the translation controls displayed for chat messages and forum posts. The affected templates inserted message and post identifiers directly into inline JavaScript onclick handlers: onclick="translateMessageToPreferredLanguage('{{ message['id'] }}', '{{ mess_id_escape }}', this)" and: onclick="translatePostToPreferredLanguage('{{ post['id'] }}', '{{ post_id_escape }}', this)" These values were HTML-template escaped but were not safely encoded for use as JavaScript string literals inside an HTML attribute. A specially crafted identifier containing quotation marks, escape characters, or other JavaScript syntax could therefore terminate the expected string argument and inject arbitrary JavaScript into the event handler. Because the affected values are associated with indexed chat messages or forum posts, a malicious value may remain stored by AIL and be rendered whenever an analyst accesses the corresponding chat or forum explorer view. Successful exploitation requires the victim to click the affected Translate to preferred language button. The injected code would then execute in the victim’s browser under the security origin of the AIL instance.
