I think with "permission" you mean "access level",
so your question/issue is duplicate, you missed this thread:
#8569

No I mean tag component permissions, not ACL on a tag.
This link /administrator/index.php?option=com_config&view=component&component=com_tags#permissions

hhmm, i miss-read your original post,
i thought you meant per indivudual tag permissions,

• a per tag assignment ACL

i will test

Tested

I confirm the bug,

• the "create" ACL of tag component is respected in the tags management,
• but it is not used / respected in article edit form, in article edit form an editor is always allowed to create

but the edit permission is also broken in 3 ways
if the user is not given "edit" ACL then

• the existing tag assigments are not shown, they should be shown as readonly
• the user despite not having edit , user can still change them
• if user does not change them, and just saves the form, the old tag assignments are lost

strange how these have escaped or are these recently introduced bugs ?

@ggppdk @Terrox i think this is solved in latest staging. can you confirm?

without testing now, I do remember that i had tested a PR that fixed checking "create" ACL for tags

ok i think it's solved by this #11211

I am closing this at this time as resolved by #11211 if that isnt the case it can always be reopened
