Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The vulnerability is forced OGNL evaluation when evaluated on raw user input in tag attributes, which may lead to remote code execution. It affects Apache Struts versions 2.0.0 through 2.5.25 and is associated with CWE-917.

An attacker can exploit the issue remotely over a network without authentication or user interaction, as reflected in the CVSS 3.1 score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), resulting in arbitrary code execution with full impact on confidentiality, integrity, and availability.
