CVE-2026-105997: Booking Package < 1.7.33 - Unauthenticated Verification Email Sending to Arbitrary Recipient

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: 0.29% (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 Booking Package 1.7.33.

Low priority for now. Upgrade to Unknown Booking Package 1.7.33 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 Booking Package WordPress plugin before 1.7.33 does not restrict who can trigger its booking verification-code emails nor bind the recipient to server-side state, allowing unauthenticated users to make the site send templated verification-code emails to arbitrary recipients.
