Noroxi assessment

Priority: Monitor (action score 10/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.29% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Unknown Schema & Structured Data for WP & AMP 1.66.

Low priority for now. Upgrade to Unknown Schema & Structured Data for WP & AMP 1.66 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

The Schema & Structured Data for WP & AMP WordPress plugin before 1.66 does not check that a user is allowed to edit the specific post they request schema generation for, allowing users with the contributor role and above to obtain the content of other users' draft, pending, private and password protected posts.
