## Technical details

A use-after-free vulnerability exists in fts3BestSnippet() when SQLite is built with FTS3/FTS4 and SQLITE_ENABLE_FTS3_PARENTHESIS enabled. Attackers trigger the bug by executing a full-text MATCH query combining OR and NEAR operators with the snippet() function, causing the code to reference dangling cached position-list pointers. Successful exploitation results in heap memory disclosure or process crash.
