During June 2026, contributed to the google/oss-fuzz repository by developing a fuzz target focused on the deserialization path of BloomFilter.readFrom(). This work involved implementing BloomFilterReadFromFuzzer in Java, leveraging fuzz testing and security testing techniques to identify vulnerabilities such as OutOfMemoryError during deserialization. The approach included comprehensive end-to-end validation, covering infrastructure builds and randomized fuzz runs to ensure robust detection of security issues. By expanding OSS-Fuzz coverage for Guava’s BloomFilter, the contribution enhanced the security and reliability of serialization paths, reducing production risk for dependent projects and demonstrating practical integration of fuzzing within a large-scale open source pipeline.
