As reported to the lemmy devs here there is no sanity checking of links in posts currently in lemmy. Please be careful in the links you click!

Further discussion and context from the reporter here.

I really wish jerboa could show urls on links for this reason. Are there any other Android clients that do?

[–] ThatSandwichGuy@aussie.zone 4 points 1 year ago (1 children)

Connect doesn't appear to be.

It does in card and full width view, just not in list or reverse list view based on my testing just now.

Edit: It shows the domain at least. Jerboa does too in every view in 0.0.38 as far as I can tell.

Do the android apps have this issue? What would they even do with a JavaScript link?

[–] cuppaconcrete@aussie.zone 1 points 1 year ago (1 children)

Links in post body and comments don't show URLs so they could easily send ya to a malware site or gore/NSFW/IP logger site.

[–] w2qw@aussie.zone 2 points 1 year ago

True but op is talking about JavaScript links.

I'm sad that the RIF dev is making a Tildes app next, because the RIF UX around links was absolutely spectacular.

Liftoff shows the domain the link is going to, but not the entire URL. And it only shows up when going to the comments.

[–] cuppaconcrete@aussie.zone 1 points 1 year ago* (last edited 1 year ago)

Good enough! I'll switch to Liftoff today

EDIT: Liftoff isn't showing any website/url previews for the links in the post or comment text but it's working for primary URLs of posts so it's better than nothing lol

EDIT2: Actually Liftoff doesn't do anything more than Jerboa already does. It seems Boost can show URLs before opening a link but it is closed source.

checks

It looks like kbin does check for and validate these. It hands back an "invalid URL" error if the mentioned javascript: schema in the bug report for lemmy is used.

EDIT: Though I didn't try submitting to a lemmy instance and seeing whether kbin validates links coming in from federated systems rather than locally-submitted.

EDIT2: Honestly, this should be checked in clients too to avoid a malicious server they connect to directly feeding them XSS URLs. Like, probably warrants bug reports for all clients.

Sure thanks... Wait a minute.

[–] No1@aussie.zone 4 points 1 year ago (1 children)

I'm gonna be so disappointed if at least one of those links is not a rickroll lol

[–] ThatSandwichGuy@aussie.zone 2 points 1 year ago

I would be but my school IT taught me better.

[–] TassieTosser@aussie.zone 3 points 1 year ago

Yikes. Thanks for the heads up.

[–] lodion@aussie.zone 1 points 1 year ago

Unpinning this, as lemmy 0.18.1 includes this update that limits URL links to only being http(s).

Everyone should still be wary of clicking random links on the internet of course.
