CVE-2026-77088

justhtml versions 0.9.0 through 1.21.0 are affected by a cross-site scripting (XSS) vulnerability in the to_markdown() function. The root cause is that inline code spans fail to treat blank lines as block boundaries. An attacker can inject blank lines into or element text to break the inline sp...

EUVD-2026-64657

justhtml versions 0.9.0 through 1.21.0 contain a cross-site scripting vulnerability in tomarkdown where inline code spans fail to account for blank lines as block boundaries. Attackers can inject blank lines into code or pre element text to break the inline span, causing sanitized HTML to be...

CVE-2026-6827

justhtml before 1.17.0 (a Python HTML sanitization library) contains multiple security flaws in sanitization, serialization, and programmatic DOM handling. When custom policies preserve foreign namespaces (SVG/MathML), HTML integration points such as SVG and MathML can survive sanitization and ...

EUVD-2026-64656

justhtml before 3.11.0 contains a cross-site scripting vulnerability where the default sanitizer bypasses event handler removal in selectedcontent projections. Attackers can inject SVG or MathML elements with event handlers that are cloned and reinserted into output without sanitization, enabling...

CVE-2026-74793

justhtml versions before 3.11.0 are affected by a cross-site scripting (XSS) vulnerability in the default sanitizer.
