A rung lights from a row in the index, never from an assessment. "Held sources" is the true scope of the claim: this index reads the CVE record, NVD, CISA KEV, FIRST's EPSS and public proof-of-concept repositories, and it does not observe attacks.
What it is stated by the CNA
Joomla Extension - joomlacontenteditor.net - Creation of hidden files and unintended file overwrite via rename function in Joomla Content Editor (JCE) < 2.20.2 - Improper input validation in the file rename functionality allowed an authenticated user with file management permissions to rename files to otherwise invalid names, resulting in the creation of hidden files. The issue also allowed existing files at the destination path to be unintentionally replaced. receipt

The pattern, elsewhere
This record is one instance of CWE-20, improper input validation. The index holds 13347 prior instances of this class, 73 KEV-listed. The nearest of its KEV-listed records are drawn beside this. [email protected]
"Matches n of m" counts the attributes the two records can both be compared on: the CVSS metrics they share a version of, any weakness class beyond this one, and the vendor. fit-rules@v1
13347 records in this class held. The six above are drawn from the ones CISA has listed as exploited, ranked by how much of the record matches this one. That is why every one of them is KEV-listed: the pool is, so the colour on those spokes says nothing the pool has not already said.
No curated product neighbourhood is held for this product, so the records above are the nearest this index can name. The neighbourhood table covers a small set of products and is extended by hand.

No record cites this identifier and it carries no alias. The advisory that covers it is below.
Fixed with these, by one advisory
Of the 2 records in this advisory, this is the only one that does not hold a CISA KEV listing. That is a fact about what the catalogue records, not a finding about exposure.
Listed because one advisory covers them, not because they are the same defect. Each record's own state is on its own page.
