The Optimizely Assistant chrome extension is running an ancient version of jQuery, as reported by this security analysis tool: https://crxcavator.io/report/hkmpnondmidmfdlaphahbalnmphelnfo?platform=Chrome
You are currently using a version of jQuery that is more than 10 years old, and which has security vulnerabilities. This is causing my infosec team to not approve the extension for use within my organisation. Please update it.
