Mozilla developer Jan de Mooij reported an issue that affects web content that relies on the Caja Compiler for protection, or other similar sandboxing libraries. He found that some JavaScript objects marked as non-extensible within Caja and Secure EcmaScript could be made extensible again, bypassing the Caja sandboxing security measures, when the JavaScript code should not be allowed to run.
