LucaCappelletti94 opened a new pull request, #2201:
URL: https://github.com/apache/datafusion-sqlparser-rs/pull/2201
Parsing `SET AUTHORIZATION <value>` without a scope modifier (e.g.
`SESSION`, `LOCAL`) causes a panic due to an `.expect()` call on a `None` value
in `parse_set`. This was discovered via a fuzz-like input string but is
trivially reproducible with any `SET AUTHORIZATION ...` statement that omits
the scope keyword.
The panic occurs at mod.rs:
```rust
scope: scope.expect("SET ... AUTHORIZATION must have a scope"),
```
Valid SQL requires a scope modifier, e.g. `SET SESSION AUTHORIZATION
'user'`, so the missing scope is indeed an error — but it should be a graceful
`ParserError`, not a panic.
Closes #2200
