Noroxi assessment

Priority: Monitor (action score 21/100)

  • 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: 0.30% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: Unknown EmbedPress 4.6.4.

Low priority for now. Upgrade to Unknown EmbedPress 4.6.4 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 EmbedPress WordPress plugin before 4.6.4 does not have proper authorization on a public review-loading action, allowing unauthenticated users to force the site to make repeated billable third-party API requests using the site's own configured API key, and to create an unbounded number of attacker-controlled rows in the database.
