udv@v1 · unaudited · wrong for you until you say what you run

$4.99M is the cost of a breach that happened, from IBM Cost of a Data Breach Report 2026, global average. It is not the value of any asset of yours. That average already covers breaches of every severity, so scaling it by exposure understates a partial-impact record. That is an assumption, not a measurement. Your own asset value goes in the decision record.

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.

Did this affect your environment?Answering needs an account.

What it is stated by the CNA

Samba 3.2.x through 3.6.x before 3.6.20, 4.0.x before 4.0.11, and 4.1.x before 4.1.1, when vfs_streams_depot or vfs_streams_xattr is enabled, allows remote attackers to bypass intended file restrictions by leveraging ACL differences between a file and an associated alternate data stream (ADS). receipt

The pattern, elsewhere

This record is one instance of CWE-264. The index holds 5502 prior instances of this class, 3 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

5502 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.
