rails-html-sanitizer\n## Summary\n\nThere is a possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer.\n\n- Versions affected: ALL\n- Not affected: NONE\n- Fixed versions: 1.4.4\n\n\n## Impact\n\nA possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer may allow an attacker to inject content if the application developer has overridden the sanitizer's allowed tags in either of the following ways:\n\n- allow both \"math\" and \"style\" elements,\n- or allow both \"svg\" and \"style\" elements\n\nCode is only impacted if allowed tags are being overridden. Applications may be doing this in four different ways:\n\n1. using application configuration:\n\n ```ruby\n # In config/application.rb\n config.action_view.sanitized_allowed_tags = [\"math\", \"style\"]\n # or\n config.action_view.sanitized_allowed_tags = [\"svg\", \"style\"]\n ```\n\n see https://guides.rubyonrails.org/configuring.html#configuring-action-view\n\n2. using a `:tags` option to the Action View helper `sanitize`:\n\n ```\n <%= sanitize @comment.body, tags: [\"math\", \"style\"] %>\n <%# or %>\n <%= sanitize @comment.body, tags: [\"svg\", \"style\"] %>\n ```\n\n see https://api.rubyonrails.org/classes/ActionView/Helpers/SanitizeHelper.html#method-i-sanitize\n\n3. using Rails::Html::SafeListSanitizer class method `allowed_tags=`:\n\n ```ruby\n # class-level option\n Rails::Html::SafeListSanitizer.allowed_tags = [\"math\", \"style\"]\n # or\n Rails::Html::SafeListSanitizer.allowed_tags = [\"svg\", \"style\"]\n ```\n\n4. using a `:tags` options to the Rails::Html::SafeListSanitizer instance method `sanitize`:\n\n ```ruby\n # instance-level option\n Rails::Html::SafeListSanitizer.new.sanitize(@article.body, tags: [\"math\", \"style\"])\n # or\n Rails::Html::SafeListSanitizer.new.sanitize(@article.body, tags: [\"svg\", \"style\"])\n ```\n\nAll users overriding the allowed tags by any of the above mechanisms to include ((\"math\" or \"svg\") and \"style\") should either upgrade or use one of the workarounds immediately.\n\n\n## Workarounds\n\nRemove \"style\" from the overridden allowed tags, or remove \"math\" and \"svg\" from the overridden allowed tags.\n\n\n## References\n\n- [CWE - CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

sanitization is enabled and the application developer has overridden the sanitizer's allowed tags in the following way:\n\n- the \"noscript\" element is explicitly allowed\n\nCode is only impacted if Rails is configured to use HTML5 sanitization, please see documentation for [`config.action_view.sanitizer_vendor`](https://guides.rubyonrails.org/configuring.html#config-action-view-sanitizer-vendor) and [`config.action_text.sanitizer_vendor`](https://guides.rubyonrails.org/configuring.html#config-action-text-sanitizer-vendor) for more information on these configuration options.\n\nThe default configuration is to disallow all of these elements. Code is only impacted if allowed tags are being overridden. Applications may be doing this in a few different ways:\n\n1. using application configuration to configure Action View sanitizers' allowed tags:\n\n ```ruby\n # In config/application.rb\n config.action_view.sanitized_allowed_tags = [\"noscript\"]\n ```\n\n see https://guides.rubyonrails.org/configuring.html#configuring-action-view\n\n2. using a `:tags` option to the Action View helper `sanitize`:\n\n ```\n <%= sanitize @comment.body, tags: [\"noscript\"] %>\n ```\n\n see https://api.rubyonrails.org/classes/ActionView/Helpers/SanitizeHelper.html#method-i-sanitize\n\n3. setting Rails::HTML5::SafeListSanitizer class attribute `allowed_tags`:\n\n ```ruby\n # class-level option\n Rails::HTML5::SafeListSanitizer.allowed_tags = [\"noscript\"]\n ```\n\n (note that this class may also be referenced as `Rails::Html::SafeListSanitizer`)\n\n4. using a `:tags` options to the Rails::HTML5::SafeListSanitizer instance method `sanitize`:\n\n ```ruby\n # instance-level option\n Rails::HTML5::SafeListSanitizer.new.sanitize(@article.body, tags: [\"noscript\"])\n ```\n\n (note that this class may also be referenced as `Rails::Html::SafeListSanitizer`)\n\n5. setting ActionText::ContentHelper module attribute `allowed_tags`:\n\n ```ruby\n ActionText::ContentHelper.allowed_tags = [\"noscript\"]\n ```\n\nAll users overriding the allowed tags by any of the above mechanisms to include \"noscript\" should either upgrade or use one of the workarounds.\n\n\n## Workarounds\n\nAny one of the following actions will work around this issue:\n\n- Remove \"noscript\" from the overridden allowed tags,\n- Or, downgrade sanitization to HTML4 (see documentation for [`config.action_view.sanitizer_vendor`](https://guides.rubyonrails.org/configuring.html#config-action-view-sanitizer-vendor) and

"vulnerability_id": "VCID-rhb1-h2b8-jucb", "summary": "rails-html-sanitizer has XSS vulnerability with certain configurations\n## Summary\n\nThere is a possible XSS vulnerability with certain configurations of Rails::HTML::Sanitizer 1.6.0 when used with Rails >= 7.1.0.\n\n* Versions affected: 1.6.0\n* Not affected: < 1.6.0\n* Fixed versions: 1.6.1\n\n## Impact\n\nA possible XSS vulnerability with certain configurations of Rails::HTML::Sanitizer may allow an attacker to inject content if HTML5 sanitization is enabled and the application developer has overridden the sanitizer's allowed tags in the following way:\n\n- the \"style\" element is explicitly allowed\n- the \"svg\" or \"math\" element is not allowed\n\nCode is only impacted if Rails is configured to use HTML5 sanitization, please see documentation for [`config.action_view.sanitizer_vendor`](https://guides.rubyonrails.org/configuring.html#config-action-view-sanitizer-vendor) and [`config.action_text.sanitizer_vendor`](https://guides.rubyonrails.org/configuring.html#config-action-text-sanitizer-vendor) for more information on these configuration options.\n\nThe default configuration is to disallow all of these elements. Code is only impacted if allowed tags are being overridden. Applications may be doing this in a few different ways:\n\n1. using application configuration to configure Action View sanitizers' allowed tags:\n\n ```ruby\n # In config/application.rb\n config.action_view.sanitized_allowed_tags = [\"style\"]\n ```\n\n see https://guides.rubyonrails.org/configuring.html#configuring-action-view\n\n2. using a `:tags` option to the Action View helper `sanitize`:\n\n ```\n <%= sanitize @comment.body, tags: [\"style\"] %>\n ```\n\n see https://api.rubyonrails.org/classes/ActionView/Helpers/SanitizeHelper.html#method-i-sanitize\n\n3. setting Rails::HTML5::SafeListSanitizer class attribute `allowed_tags`:\n\n ```ruby\n # class-level option\n Rails::HTML5::SafeListSanitizer.allowed_tags = [\"style\"]\n ```\n\n (note that this class may also be referenced as `Rails::Html::SafeListSanitizer`)\n\n4. using a `:tags` options to the Rails::HTML5::SafeListSanitizer instance method `sanitize`:\n\n ```ruby\n # instance-level option\n Rails::HTML5::SafeListSanitizer.new.sanitize(@article.body, tags: [\"style\"])\n ```\n\n (note that this class may also be referenced as `Rails::Html::SafeListSanitizer`)\n\n5. setting ActionText::ContentHelper module attribute `allowed_tags`:\n\n ```ruby\n ActionText::ContentHelper.allowed_tags = [\"style\"]\n ```\n\nAll users overriding the allowed tags by any of the above mechanisms to include \"style\" and omit \"svg\" or \"math\" should either upgrade or use one of the workarounds.\n\n\n## Workarounds\n\nAny one of the following actions will work around this issue:\n\n- Remove \"style\" from the overridden allowed tags,\n- Or, downgrade sanitization to HTML4 (see documentation for [`config.action_view.sanitizer_vendor`](https://guides.rubyonrails.org/configuring.html#config-action-view-sanitizer-vendor) and [`config.action_text.sanitizer_vendor`](https://guides.rubyonrails.org/configuring.html#config-action-text-sanitizer-vendor) for more information).\n\n\n## References\n\n- [CWE - CWE-79: Improper

configurations\n## Summary\n\nThere is a possible XSS vulnerability with certain configurations of Rails::HTML::Sanitizer 1.6.0 when used with Rails >= 7.1.0.\n\n* Versions affected: 1.6.0\n* Not affected: < 1.6.0\n* Fixed versions: 1.6.1\n\n## Impact\n\nA possible XSS vulnerability with certain configurations of Rails::HTML::Sanitizer may allow an attacker to inject content if HTML5 sanitization is enabled and the application developer has overridden the sanitizer's allowed tags in the following way:\n\n- the \"math\", \"mtext\", \"table\", and \"style\" elements are allowed\n- and either \"mglyph\" or \"malignmark\" are allowed\n\nCode is only impacted if Rails is configured to use HTML5 sanitization, please see documentation for [`config.action_view.sanitizer_vendor`](https://guides.rubyonrails.org/configuring.html#config-action-view-sanitizer-vendor) and [`config.action_text.sanitizer_vendor`](https://guides.rubyonrails.org/configuring.html#config-action-text-sanitizer-vendor) for more information on these configuration options.\n\nThe default configuration is to disallow all of these elements except for \"table\". Code is only impacted if allowed tags are being overridden. Applications may be doing this in a few different ways:\n\n1. using application configuration to configure Action View sanitizers' allowed tags:\n\n ```ruby\n # In config/application.rb\n config.action_view.sanitized_allowed_tags = [\"math\", \"mtext\", \"table\", \"style\", \"mglyph\"]\n # or\n config.action_view.sanitized_allowed_tags = [\"math\", \"mtext\", \"table\", \"style\", \"malignmark\"]\n ```\n\n see https://guides.rubyonrails.org/configuring.html#configuring-action-view\n\n2. using a `:tags` option to the Action View helper `sanitize`:\n\n ```\n <%= sanitize @comment.body, tags: [\"math\", \"mtext\", \"table\", \"style\", \"mglyph\"] %>\n <%# or %>\n <%= sanitize @comment.body, tags: [\"math\", \"mtext\", \"table\", \"style\", \"malignmark\"] %>\n ```\n\n see https://api.rubyonrails.org/classes/ActionView/Helpers/SanitizeHelper.html#method-i-sanitize\n\n3. setting Rails::HTML5::SafeListSanitizer class attribute `allowed_tags`:\n\n ```ruby\n # class-level option\n Rails::HTML5::SafeListSanitizer.allowed_tags = [\"math\", \"mtext\", \"table\", \"style\", \"mglyph\"]\n # or\n Rails::HTML5::SafeListSanitizer.allowed_tags = [\"math\", \"mtext\", \"table\", \"style\", \"malignmark\"]\n ```\n\n (note that this class may also be referenced as `Rails::Html::SafeListSanitizer`)\n\n4. using a `:tags` options to the Rails::HTML5::SafeListSanitizer instance method `sanitize`:\n\n ```ruby\n # instance-level option\n Rails::HTML5::SafeListSanitizer.new.sanitize(@article.body, tags: [\"math\", \"mtext\", \"table\", \"style\", \"mglyph\"])\n # or\n Rails::HTML5::SafeListSanitizer.new.sanitize(@article.body, tags: [\"math\", \"mtext\", \"table\", \"style\", \"malignmark\"])\n ```\n\n (note that this class may also be referenced as `Rails::Html::SafeListSanitizer`)\n\n5. setting ActionText::ContentHelper module attribute `allowed_tags`:\n\n ```ruby\n ActionText::ContentHelper.allowed_tags = [\"math\", \"mtext\", \"table\", \"style\", \"mglyph\"]\n # or\n ActionText::ContentHelper.allowed_tags = [\"math\", \"mtext\", \"table\", \"style\", \"malignmark\"]\n ```\n\nAll users overriding the allowed tags by any of the above mechanisms to include (\"math\" and \"mtext\" and \"table\" and \"style\" and (\"mglyph\" or \"malignmark\")) should either upgrade or use one of the workarounds.\n\n\n## Workarounds\n\nAny one of the following actions will work around this issue:\n\n- Remove \"mglyph\" and \"malignmark\" from the overridden allowed tags,\n- Or, downgrade sanitization to HTML4 (see documentation for [`config.action_view.sanitizer_vendor`](https://guides.rubyonrails.org/configuring.html#config-action-view-sanitizer-vendor) and [`config.action_text.sanitizer_vendor`](https://guides.rubyonrails.org/configuring.html#config-action-text-sanitizer-vendor) for more information).\n\n\n## References\n\n- [CWE - CWE-79: Improper

This is due to an incomplete fix of CVE-2022-32209.\n\n- Versions affected: ALL\n- Not affected: NONE\n- Fixed versions: 1.4.4\n\n\n## Impact\n\nA possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer may allow an attacker to inject content if the application developer has overridden the sanitizer's allowed tags to allow both \"select\" and \"style\" elements.\n\nCode is only impacted if allowed tags are being overridden using either of the following two mechanisms:\n\n1. Using the Rails configuration `config.action_view.sanitized_allow_tags=`:\n\n ```ruby\n # In config/application.rb\n config.action_view.sanitized_allowed_tags = [\"select\", \"style\"]\n ```\n\n (see https://guides.rubyonrails.org/configuring.html#configuring-action-view)\n\n2. Using the class method `Rails::Html::SafeListSanitizer.allowed_tags=`:\n\n ```ruby\n # class-level option\n Rails::Html::SafeListSanitizer.allowed_tags = [\"select\", \"style\"]\n ```\n\nAll users overriding the allowed tags by either of the above mechanisms to include both \"select\" and \"style\" should either upgrade or use one of the workarounds immediately.\n\nNOTE: Code is _not_ impacted if allowed tags are overridden using either of the following mechanisms:\n\n- the `:tags` option to the Action View helper method `sanitize`.\n- the `:tags` option to the instance method `SafeListSanitizer#sanitize`.\n\n\n## Workarounds\n\nRemove either \"select\" or \"style\" from the overridden allowed tags.\n\n\n## References\n\n- [CWE - CWE-79: Improper Neutralization of Input
