CVE-2024-45626Network attack vector

Authenticated service crash via recursive HTML flattening

Published Feb 6, 2025 · Updated Feb 12, 2025

Resource exhaustion in Apache James Server before 3.7.6 and 3.8.0 through 3.8.1 allows remote authenticated users to crash the service. JsoupHtmlTextExtractor recursively flattens the user-supplied HTML DOM into nested streams, allowing deeply nested markup to exhaust stack or memory. A valid account and access to the JMAP HTML-to-text conversion path are required, and the reported consequence is service interruption.
