Apache Struts 2 - information disclosure, DoS, SSRF (CVE-2025-68493)

Under certain conditions, an unauthenticated remote attacker can send specially crafted XML to obtain potentially sensitive server data, perform a DoS attack, or possibly SSRF. The vulnerability affects the XWork component. If an immediate update is not possible, the risk can be temporarily mitigated by changing the configuration at the JVM level or by setting 'xwork.saxParserFactory=' to a custom class that disables external entities. More information on temporary workarounds can be found at [1].
