Hi,

The following vulnerability was published for jsoup.

CVE-2026-75140[0]:
| jsoup through 1.23.2, fixed in commit 862ba2f, contains an
| uncontrolled resource consumption vulnerability in XmlTreeBuilder
| that allows remote attackers to exhaust JVM heap memory by supplying
| a deeply nested XML document with uniquely-namespaced elements. The
| builder copies the entire inherited namespace map on every start
| element, causing quadratic time and memory complexity, which
| attackers can exploit to trigger an OutOfMemoryError and terminate
| the application.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
