In this webinar excerpt, our colleague Peter Samarin demonstrates how our prototype pollution bug detectors were able to uncover a highly severe CVE in the popular JavaScript library protobufjs. This finding puts affected applications at risk of remote code execution and denial of service attacks.

Our colleagues Peter Samarin, Norbert Schneider and Fabian Meumertzheim recently built a new bug detector enabling our JavaScript fuzzing engine Jazzer.js to identify Prototype Pollution. This work is now bearing its first fruits: As part of our ongoing collaboration with Google’s OSS-Fuzz, Jazzer.js recently uncovered a new Prototype Pollution vulnerability in protobuf.js (CVE-2023-36665). This finding puts affected applications at risk of remote code execution and denial of service attacks.
