CVE-2026-56453

Status: AnalyzedCritical (9.8)—

HCL DFXAnalytics is affected by an Account Takeover via Response Manipulation vulnerability. A remote attacker can intercept and alter the contents of the server's HTTP responses before they reach the client application, allowing them to manipulate the authentication or authorization logic to bypass controls and gain unauthorized access to targeted user accounts.

CVSS

Version: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Base score: 9.8

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.35%
Percentile among all scored CVEs: 27
Score date: 10/5/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
