Ensure protocol sanitization is applied to data attributes. [@ccutrer - #207]207
v5.2.2
Bug Fixes
Fixed a deprecation warning in Ruby 2.7+ when using keyword arguments in a custom transformer. [@mscrivo - #206]206
v5.2.1
Bug Fixes
Fixed an HTML sanitization bypass that could allow XSS. This issue affects Sanitize versions 3.0.0 through 5.2.0.
When HTML was sanitized using the "relaxed" config or a custom config that allows certain elements, some content in a <math> or <svg> element may not have beeen sanitized correctly even if math and svg were not in the allowlist. This could allow carefully crafted input to sneak arbitrary HTML through Sanitize, potentially enabling an XSS (cross-site scripting) attack.
You are likely to be vulnerable to this issue if you use Sanitize's relaxed config or a custom config that allows one or more of the following HTML elements:
iframe
math
noembed
noframes
noscript
plaintext
script
style
svg
xmp
See the security advisory for more details, including a workaround if you're not able to upgrade: GHSA-p4x4-rw2p-8j8m
Many thanks to Michał Bentkowski of Securitum for reporting this issue and helping to verify the fix.
v5.2.0
Changes
The term "whitelist" has been replaced with "allowlist" throughout Sanitize's source and documentation.
While the etymology of "whitelist" may not be explicitly racist in origin or intent, there are inherent racial connotations in the implication that white is good and black (as in "blacklist") is not.
This is a change I should have made long ago, and I apologize for not making it sooner.
In transformer input, the :is_whitelisted and :node_whitelist keys are now deprecated. New :is_allowlisted and :node_allowlist keys have been added. The old keys will continue to work in order to avoid breaking existing code, but they are no longer documented and may be removed in a future semver major release.
Ensure protocol sanitization is applied to data attributes.
