org.jsoup/jsoup: jsoup: Cross-site scripting via malformed HTML tag names

A flaw was found in jsoup, a Java library for working with HTML. The HTML parser incorrectly handles malformed tag names ending in a control character. When a custom Safelist allows certain raw-text elements, this misparsing can cause content that should be inert to be processed as active markup...

PT-2026-68974

When a custom Safelist permits certain raw-text elements, jsoup may incorrectly sanitize malformed HTML containing a tag name that ends in a control character. The tag may acquire the parsing behavior of a different element, causing content that should remain text to be emitted as active markup...

CVE-2026-52846

A flaw was found in Caddy, an extensible server platform. The stripHTML template function, intended to remove HTML tags from input, fails to reliably process certain malformed HTML. This oversight allows dangerous content to remain in the output, which, if subsequently rendered as HTML, can lead ...

Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop via the HTMLParser process. An attacker can cause excessive CPU consumption and render the system unresponsive by supplying specially crafted, malformed HTML with repeated unterminated markup declarations. Remediation A fi...
