Editor crash via Java parser stack exhaustion
Published Aug 31, 2026 · Updated Aug 31, 2026
Uncontrolled recursion in Bare Bones Software BBEdit 15.5.0 through 15.5.5 allows remote attackers to crash the editor via crafted Java source. The Java language module recursively parses attacker-controlled source constructs without a recursion bound, exhausting the process stack. Exploitation requires a user to open the crafted file; the resulting availability impact is limited to the BBEdit process, with no reported data disclosure or modification.
