Is it possible to avoid/restrict entering the hyperlinks in Pulse post OOTB. There is a chance that users might use this as a messenger and type the illegal links and try to access it from other system.
OOTB Pega Pulse allows users to post links, so there is no straightforward built-in setting to block all hyperlinks completely. If the requirement is to prevent unsafe or illegal links, the recommended approach is to add custom validation or sanitization before the post is saved, and optionally remove the link-related UI options where possible. If you only need to control references and mentions, Pega provides extension points for those behaviors.
Thanks, I am looking for overall solution where it is generic. In case of Validate it will just be applied to PegaSocial-Post class. Can we use CORS policy somehow so that there will be a warning for the user submit spam links?
I would not recommend CORS for this. CORS controls which external origins can access Pega resources but it does not validate or warn on the content that a user types into a Pulse post.
For this requirement, the more appropriate controls are:
- validation/sanitization of the Pulse post content before save,
- optionally rendering URLs as plain text instead of clickable links,
- using Content Security Policy (CSP) to restrict which external sources the browser can load from the application context.
So if the goal is βwarn/block spam or illegal links,β that should be handled as content validation, not by CORS.
