RUSTSEC-2025-0071
No affected components available
Affected versions of this crate did not correctly strip namespace-incompatible tags in certain situations, causing it to incorrectly account for differences between HTML, SVG, and MathML.
This vulnerability only has an effect when the svg or math tag is allowed,
because it relies on a tag being parsed as html during the cleaning process, but
serialized in a way that causes in to be parsed as xml by the browser.
Additionally, the application using this library must allow a tag that is parsed as raw text in HTML. These elements are:
- title
- textarea
- xmp
- iframe
- noembed
- noframes
- plaintext
- noscript
- style
- script
Applications that do not explicitly allow any of these tags should not be affected, since none are allowed by default.
Measures severity based on intrinsic characteristics of the vulnerability, independent of environment.
