  • Probability of exploitation in the next 30 days: 0.26% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: Unknown EmbedPress 4.6.7.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Unknown EmbedPress 4.6.7 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 4.6.7 does not escape one of its block attributes before outputting it inside an HTML attribute, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks against higher privileged users viewing the post.
