Deeper analysis AI-assisted summary

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

CVE-2025-52659 is a Cacheable HTTP Response vulnerability, classified under CWE-525, affecting HCL AION version 2. This flaw may result in the unintended storage of sensitive or dynamic content in caches, potentially enabling unauthorized access or information disclosure. The vulnerability received a CVSS v3.1 base score of 2.8 (AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L) and was published on 2026-01-19.

Exploitation requires local access, low attack complexity, low privileges, and user interaction. A local attacker with low-level privileges could trick a user into performing an action that triggers a cacheable HTTP response containing sensitive or dynamic content. While the description notes potential for unauthorized access or disclosure, the CVSS metrics indicate no confidentiality or integrity impact, with effects limited to low availability disruption.

Mitigation guidance is available in the HCL Software support knowledge base article at https://support.hcl-software.com/kb_view.do?sys_kb_id=4b92474633de7ad4159a05273e5c7b4b&searchTerm=kb0127995#.
