- Website owners and people responsible for site maintenance
- Worth noticing
- The scanner says it uses passive public-page requests only; it does not log in, submit forms, or attempt exploits.
Field notes
The page lays out example GET requests and a sample notice, including the version strings and vulnerability references that would support an alert. It names NVD, CISA KEV, EPSS, and endoflife.date as comparison sources, and offers technical links to matching methodology and raw JSON. PatchNotice also acknowledges that distribution backports and conditional CVEs can make a version match misleading.
