HCL MyXalytics: Improperly Controlled Modification of Dynamically-Determined Object Attributes

CVE-2025-52656 is a high-severity improperly controlled modification of dynamically-determined object attributes vulnerability in HCL MyXalytics from HCL, with a CVSS 3.1 base score of 7.6 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. Affected HCL MyXalytics versions: 6.6. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.25% chance of exploitation within 30 days, which is low compared with other CVEs.

High severity with no evidence of exploitation so far.

What to do

  1. Check which version of HCL MyXalytics you run against the affected versions below, and install the vendor's latest release.
  2. Read the advisory on support.hcl-software.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
  4. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

HCL MyXalytics: 6.6. is affected by Mass Assignment vulnerability. Mass Assignment occurs when user input is automatically bound to application objects without proper validation or access controls, potentially allowing unauthorized modification of sensitive fields.

The underlying weakness: Improperly Controlled Modification of Dynamically-Determined Object Attributes

The product receives input from an upstream component that specifies multiple attributes, properties, or fields that are to be initialized or updated in an object, but it does not properly control which attributes can be modified.

How developers prevent this class of flaw

  • If available, use features of the language or framework that allow specification of allowlists of attributes or fields that are allowed to be modified. If possible, prefer allowlists over denylists. For applications written with Ruby on Rails, use the attr_accessible (allowlist) or attr_protected (denylist) macros in each class that may be used in mass assignment.
  • If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
  • For any externally-influenced input, check the input against an allowlist of internal object attributes or fields that are allowed to be modified.
