Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
This can be leveraged to gain access to higher-privilege endpoints, e.g. if you get a user with admin privileges to run the code, you can potentially elevate all users and grant them admin privileges or access protected content.
### Patches
Will be patched in 14.3.1 and 15.0.0.
### Workarounds
Ensure that access to the Dictionary section is only granted to trusted users.
