Root Cause Analysis
The vulnerability stems from missing validation checks in the ReverseSequenceOp constructor where 'seq_dim' and 'batch_dim' attributes were retrieved but not properly validated. The commit diff explicitly shows these validations were added via OP_REQUIRES(context, ...) calls in this constructor, confirming this was the vulnerable location. The CWE mappings (CWE-119, CWE-787) and vulnerability description directly correlate to this lack of bounds checking in dimension arguments.
