Details
As written in the advisory (Markdown source, shown as plain text).
Authenticated users on a Craft installation could potentially expose sensitive assets via their user profile photo via maliciously crafted requests.
Users should update to the patched versions (5.8.21 and 4.16.17) to mitigate the issue.
