  • 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 Limit Login Attempts Security 3.4.2.

Low priority for now. Upgrade to Unknown Limit Login Attempts Security 3.4.2 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

Primary sources: NVD · CVE.org · FIRST EPSS

The Limit Login Attempts Security WordPress plugin before 3.4.2 does not validate the destination of a server-side request built from a user-supplied setup value, allowing users with administrator privileges to make the site issue requests to arbitrary hosts, including internal ones (SSRF).
