Not affected: None Fixed Versions: 7.0.4.3, 6.1.7.3\n\n# Impact\n\nActiveSupport uses the SafeBuffer string subclass to tag strings as html_safe after they have been sanitized.\nWhen these strings are mutated, the tag is should be removed to mark them as no longer being html_safe.\n\nRuby 3.2 introduced a new bytesplice method which ActiveSupport did not yet understand to be a mutation.\nUsers on older versions of Ruby are likely unaffected.\n\nAll users running an affected release and using bytesplice should either upgrade or use one of the workarounds immediately.\n\n# Workarounds\n\nAvoid calling bytesplice on a SafeBuffer (html_safe) string with untrusted user input.\n","affected":[{"package":{"name":"activesupport","ecosystem":"RubyGems","purl":"pkg:gem/activesupport"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.0.4.3"}]}],"versions":["7.0.0","7.0.1","7.0.2","7.0.2.1","7.0.2.2","7.0.2.3","7.0.2.4","7.0.3","7.0.3.1","7.0.4","7.0.4.1","7.0.4.2"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/03/GHSA-pj73-v5mw-pm9j/GHSA-pj73-v5mw-pm9j.json"}},{"package":{"name":"activesupport","ecosystem":"RubyGems","purl":"pkg:gem/activesupport"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.7.3"}]}],"versions":["1.0.0","1.0.1","1.0.2","1.0.3","1.0.4","1.1.0","1.1.1","1.2.1","1.2.2","1.2.3","1.2.4","1.2.5","1.3.0","1.3.1","1.4.0","1.4.1","1.4.2","1.4.3","1.4.4","2.0.0","2.0.1","2.0.2","2.0.4","2.0.5","2.1.0","2.1.1","2.1.2","2.2.2","2.2.3","2.3.10","2.3.11","2.3.12","2.3.14","2.3.15","2.3.16","2.3.17","2.3.18","2.3.2","2.3.3","2.3.4","2.3.5","2.3.6","2.3.6.pre","2.3.7","2.3.8","2.3.8.pre1","2.3.9","2.3.9.pre","3.0.0","3.0.0.beta","3.0.0.beta2","3.0.0.beta3","3.0.0.beta4","3.0.0.rc","3.0.0.rc2","3.0.1","3.0.10","3.0.10.rc1","3.0.11","3.0.12","3.0.12.rc1","3.0.13","3.0.13.rc1","3.0.14","3.0.15","3.0.16","3.0.17","3.0.18","3.0.19","3.0.2","3.0.20","3.0.3","3.0.4","3.0.4.rc1","3.0.5","3.0.5.rc1","3.0.6","3.0.6.rc1","3.0.6.rc2","3.0.7","3.0.7.rc1","3.0.7.rc2","3.0.8","3.0.8.rc1","3.0.8.rc2","3.0.8.rc4","3.0.9","3.0.9.rc1","3.0.9.rc3","3.0.9.rc4","3.0.9.rc5","3.0.pre","3.1.0","3.1.0.beta1","3.1.0.rc1","3.1.0.rc2","3.1.0.rc3","3.1.0.rc4","3.1.0.rc5","3.1.0.rc6","3.1.0.rc8","3.1.1","3.1.1.rc1","3.1.1.rc2","3.1.1.rc3","3.1.10","3.1.11","3.1.12","3.1.2","3.1.2.rc1","3.1.2.rc2","3.1.3","3.1.4","3.1.4.rc1","3.1.5","3.1.5.rc1","3.1.6","3.1.7","3.1.8","3.1.9","3.2.0","3.2.0.rc1","3.2.0.rc2","3.2.1","3.2.10","3.2.11","3.2.12","3.2.13","3.2.13.rc1","3.2.13.rc2","3.2.14","3.2.14.rc1","3.2.14.rc2","3.2.15","3.2.15.rc1","3.2.15.rc2","3.2.15.rc3","3.2.16","3.2.17","3.2.18","3.2.19","3.2.2","3.2.2.rc1","3.2.20","3.2.21","3.2.22","3.2.22.1","3.2.22.2","3.2.22.3","3.2.22.4","3.2.22.5","3.2.3","3.2.3.rc1","3.2.3.rc2","3.2.4","3.2.4.rc1","3.2.5","3.2.6","3.2.7","3.2.7.rc1","3.2.8","3.2.8.rc1","3.2.8.rc2","3.2.9","3.2.9.rc1","3.2.9.rc2","3.2.9.rc3","4.0.0","4.0.0.beta1","4.0.0.rc1","4.0.0.rc2","4.0.1","4.0.1.rc1","4.0.1.rc2","4.0.1.rc3","4.0.1.rc4","4.0.10","4.0.10.rc1","4.0.10.rc2","4.0.11","4.0.11.1","4.0.12","4.0.13","4.0.13.rc1","4.0.2","4.0.3","4.0.4","4.0.4.rc1","4.0.5","4.0.6","4.0.6.rc1","4.0.6.rc2","4.0.6.rc3","4.0.7","4.0.8","4.0.9","4.1.0","4.1.0.beta1","4.1.0.beta2","4.1.0.rc1","4.1.0.rc2","4.1.1","4.1.10","4.1.10.rc1","4.1.10.rc2","4.1.10.rc3","4.1.10.rc4","4.1.11","4.1.12","4.1.12.rc1","4.1.13","4.1.13.rc1","4.1.14","4.1.14.1","4.1.14.2","4.1.14.rc1","4.1.14.rc2","4.1.15","4.1.15.rc1","4.1.16","4.1.16.rc1","4.1.2","4.1.2.rc1","4.1.2.rc2","4.1.2.rc3","4.1.3","4.1.4","4.1.5","4.1.6","4.1.6.rc1","4.1.6.rc2","4.1.7","4.1.7.1","4.1.8","4.1.9","4.1.9.rc1","4.2.0","4.2.0.beta1","4.2.0.beta2","4.2.0.beta3","4.2.0.beta4","4.2.0.rc1","4.2.0.rc2","4.2.0.rc3","4.2.1","4.2.1.rc1","4.2.1.rc2","4.2.1.rc3","4.2.1.rc4","4.2.10","4.2.10.rc1","4.2.11","4.2.11.1","4.2.11.2","4.2.11.3","4.2.2","4.2.3","4.2.3.rc1","4.2.4","4.2.4.rc1","4.2.5","4.2.5.1","4.2.5.2","4.2.5.rc1","4.2.5.rc2","4.2.6","4.2.6.rc1","4.2.7","4.2.7.1","4.2.7.rc1","4.2.8","4.2.8.rc1","4.2.9","4.2.9.rc1","4.2.9.rc2","5.0.0","5.0.0.1","5.0.0.beta1","5.0.0.beta1.1","5.0.0.beta2","5.0.0.beta3","5.0.0.beta4","5.0.0.racecar1","5.0.0.rc1","5.0.0.rc2","5.0.1","5.0.1.rc1","5.0.1.rc2","5.0.2","5.0.2.rc1","5.0.3","5.0.4","5.0.4.rc1","5.0.5","5.0.5.rc1","5.0.5.rc2","5.0.6","5.0.6.rc1","5.0.7","5.0.7.1","5.0.7.2","5.1.0","5.1.0.beta1","5.1.0.rc1","5.1.0.rc2","5.1.1","5.1.2","5.1.2.rc1","5.1.3","5.1.3.rc1","5.1.3.rc2","5.1.3.rc3","5.1.4","5.1.4.rc1","5.1.5","5.1.5.rc1","5.1.6","5.1.6.1","5.1.6.2","5.1.7","5.1.7.rc1","5.2.0","5.2.0.beta1","5.2.0.beta2","5.2.0.rc1","5.2.0.rc2","5.2.1","5.2.1.1","5.2.1.rc1","5.2.2","5.2.2.1","5.2.2.rc1","5.2.3","5.2.3.rc1","5.2.4","5.2.4.1","5.2.4.2","5.2.4.3","5.2.4.4","5.2.4.5","5.2.4.6","5.2.4.rc1","5.2.5","5.2.6","5.2.6.1","5.2.6.2","5.2.6.3","5.2.7","5.2.7.1","5.2.8","5.2.8.1","6.0.0","6.0.0.beta1","6.0.0.beta2","6.0.0.beta3","6.0.0.rc1","6.0.0.rc2","6.0.1","6.0.1.rc1","6.0.2","6.0.2.1","6.0.2.2","6.0.2.rc1","6.0.2.rc2","6.0.3","6.0.3.1","6.0.3.2","6.0.3.3","6.0.3.4","6.0.3.5","6.0.3.6","6.0.3.7","6.0.3.rc1","6.0.4","6.0.4.1","6.0.4.2","6.0.4.3","6.0.4.4","6.0.4.5","6.0.4.6","6.0.4.7","6.0.4.8","6.0.5","6.0.5.1","6.0.6","6.0.6.1","6.1.0","6.1.0.rc1","6.1.0.rc2","6.1.1","6.1.2","6.1.2.1","6.1.3","6.1.3.1","6.1.3.2","6.1.4","6.1.4.1","6.1.4.2","6.1.4.3","6.1.4.4","6.1.4.5","6.1.4.6","6.1.4.7","6.1.5","6.1.5.1","6.1.6","6.1.6.1","6.1.7","6.1.7.1","6.1.7.2"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/03/GHSA-pj73-v5mw-pm9j/GHSA-
