CVE-2025-55261 is a missing functional level access control flaw in HCL Aftermarket DPC, scored CVSS 8.1 (high). The record says an attacker could escalate privileges and read or change data. HCL lists the remediation in its knowledge base article, so confirm the fixed build and update.
What's affected
The NVD record names HCL Aftermarket DPC, and the CPE entry is listed under aftermarket_cloud. No version ranges appear in the record. Three more CVEs from the same HCL article cover the same product: CVE-2025-55267 (file upload), CVE-2025-55269 (weak passwords) and CVE-2025-55270 (input validation).
The HCL support portal did not return article text when I fetched it, so this guide relies on the NVD record. Read the article itself for the fixed version. Because several issues share one article, one update may close all of them.
How to check if you're exposed
HCL publishes the affected and fixed builds for Aftermarket DPC in its knowledge base article, and that article is the authority. I could not read its text when preparing this guide, so I will not state a fixed version here.
- Find the build you run. The admin or about page of the product usually shows it, and so does your deployment record.
- Open the HCL article listed under Sources and compare your build with its list of affected and fixed builds.
- If the article lists a fix and you are behind it, you are exposed to the issue described here. If your build is not named, ask HCL support to confirm in writing.
A practical test for this class is to confirm that functions reserved for administrators are refused for ordinary accounts. Run that check in a test copy, with accounts you own, and never against a system you do not control.
What to do now
- Inventory every Aftermarket DPC deployment.
- Open the HCL article and note the fixed build for each CVE listed.
- Apply the update in a test environment, then in production.
- After the update, test that low privilege accounts cannot reach administrative functions.
- Review application logs from before the update for unexpected role changes or data edits, and keep what you find with your incident records.
Why it matters
The class is CWE-284, improper access control. Here the gap is at the function level: the application let an account call something its role should not allow. This is common when the interface hides a button but the server does not check the caller on each request.
That is why the severity is high. Privilege escalation turns any low rights account, such as a customer or partner login, into a path to other people's data.
Quick check
What is functional level access control?
It is the server side check that the signed in user is allowed to call a specific function, not only to see a specific page. Missing it means hiding a menu does not protect the action behind it.
