CVSS Risk Scores and More

Since we launched our WordPress vulnerability database in 2014, we have been lacking one important factor, vulnerability risk scores. This was partly due to not being able to decide on which risk scoring system to use, not having the time to implement the system, and not having the time to assign risk scores to new vulnerabilities, if the system was implemented.

Today we’re happy to announce that all new WordPress vulnerability database vulnerabilities will come with a CVSS risk score. However, these will be limited to the API and to Enterprise users for now.

Ultimate Membership Pro Premium WordPress Plugin Recent Vulnerabilities Breakdown

While checking fixes of critical issues in a premium plugin, we stumbled across an insufficient filename entropy where the PHP function time() was used to generate a part of the md5 hashed string to form the filename. These files generally contain sensitive data, such as log, PII etc and as it’s not the first we see such a mistake, we though it would be a good idea to make a post out of it.More

New Description and PoC fields in API

From today we have two new fields output in our API for enterprise users, the description and poc fields.

We have been displaying this data on the wpvulndb.com website since almost the beginning of the project, but excluded the data from the API due to concerns of the extra bandwidth costs.

We have had a number of users request the data be output within the API over the years, and quite a few recently.
