Hi Kristina, I have created a patch:
https://github.com/tuanngocnguyen/mahara/compare/main...tuanngocnguyen:mahara:bug_1992702-main I have tried "git clone git://reviews.mahara.org/git/mahara", but got time out issue. Since I am not familiar with the review process, I attach the patch here for review. It would also great if you (or someone else) can help me with the review. ** Patch added: "Bug#1992702_enable_css_trusted__position,_left,_right____Bug#1992702_add_style_as_allowed_.patch" https://bugs.launchpad.net/mahara/+bug/1992702/+attachment/5623986/+files/Bug%231992702_enable_css_trusted__position%2C_left%2C_right____Bug%231992702_add_style_as_allowed_.patch -- You received this bug notification because you are a member of Mahara Contributors, which is subscribed to Mahara.

I am looking to add 'style' as allowed attribute for iframe, but it may have some security implication, refer https://bugs.launchpad.net/mahara/+bug/1843154 There is another option, that is using 'class', but it will require user to change the embed code. Example embed code <div style="position: relative; width: 100%; height: 0; padding-top: 56.2500%; padding-bottom: 0; box-shadow: 0 2px 8px 0 rgba(63,69,81,0.16); margin-top: 1.6em; margin-bottom: 0.9em; overflow: hidden; border-radius: 8px; will-change: transform;"> <iframe loading="lazy" style="position: absolute; width: 100%; height: 100%; top: 0; left: 0; border: none; padding: 0;margin: 0;" src="https://sourceurl" allowfullscreen="allowfullscreen" allow="fullscreen"> </iframe> </div> To manage notifications about this bug go to: https://bugs.launchpad.net/mahara/+bug/1992702/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~mahara-contributors Post to : mahara-contributors@lists.launchpad.net Unsubscribe : https://launchpad.net/~mahara-contributors More help : https://help.launchpad.net/ListHelp
