justhtml before 1.15.0 contains multiple security issues in URL sanitization helpers (clean_url_value\/clean_url_in_js_string), HTML serialization, Markdown passthrough (html_passthrough=True), and several custom sanitization-policy edge cases. Depending on configuration, an attacker can bypass sanitization to inject active HTML and JavaScript \u2014 for example via encoded javascript: URLs, backslash-based relative URLs resolved as remote hosts, markup-breaking programmatic element\/attribute names or HTML comments, raw <\/textarea> reintroduction through Markdown passthrough, or preserved \/\/ tags in custom policies. Most custom-policy issues do not affect the default sanitize=True configuration; they primarily affect helper APIs, programmatic DOM construction, html_passthrough=True, and custom policies\/transform pipelines.<\/p>\n","protected":false},"excerpt":{"rendered":"
