Jailbreak exploit not given publicity? (6)
I believe the answer is:
escape
'jailbreak' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for escape that I've seen before include "Manage to avoid" , "Duck" , "Break loose - flight" , "Elude; break free" , "issue" .)
