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.
What it is stated by the CNA
An Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Schweitzer Engineering Laboratories Real-Time Automation Controller (SEL RTAC) Web Interface could allow a remote authenticated attacker to inject and execute arbitrary script code. See SEL Service Bulletin dated 2022-11-15 for more details. receipt

The full biography
The record had been public for 3 years, 1 month when this index was last written.
The pattern, elsewhere
This record is one instance of CWE-79, improper neutralization of input during web page generation ('cross-site scripting'). The index holds 47894 prior instances of this class, 32 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
47894 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.
