justhtml before 1.16.0 contains multiple HTML sanitization bypass issues that can allow active\/dangerous content (e.g., script or style) to survive sanitization, potentially leading to cross-site scripting. The issues primarily affect advanced usage rather than the default JustHTML(…, sanitize=True) path for ordinary parsed HTML: mutating or reusing sanitization policy objects (including exported defaults) could weaken later sanitization; programmatic DOM input to sanitize()\/sanitize_dom() could miss mixed-case tag names (e.g., ScRiPt, StYlE); crafted programmatic doctype names could serialize into active markup; and custom policies preserving SVG or MathML could allow animation elements, presentation attributes with external url(…) references, or DOM trees mislabeled as namespace=”html” to bypass foreign-content checks. Fixed in 1.16.0.<\/p>\n","protected":false},"excerpt":{"rendered":"
