Custom Field Template <= 2.5.1 - Cross-Site Request Forgery Bypass

Noroxi assessment

Priority: Monitor (action score 17/100)

  • 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: 0.38% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: hiroaki-miyashita Custom Field Template 2.5.2.

Low priority for now. Upgrade to hiroaki-miyashita Custom Field Template 2.5.2 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

The Custom Field Template plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.5.1. This is due to missing or incorrect nonce validation on the edit_meta_value() function. This makes it possible for unauthenticated attackers to edit meta field values via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
