CVE-2023-51410: WordPress WP Mail Log Plugin <= 1.1.2 is vulnerable to Arbitrary File Upload

Noroxi assessment

Priority: Monitor (action score 35/100)

  • 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: 0.60% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: WPVibes WP Mail Log 1.1.3.

Low priority for now. Upgrade to WPVibes WP Mail Log 1.1.3 or later.
