CVE-2026-8383: LearnPress < 4.3.7 - Unauthenticated Sensitive User Information Disclosure via REST API

Noroxi assessment

Priority: Monitor (action score 23/100)

  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (Exploit-DB / GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 7.6% (FIRST EPSS); higher than 94.5% of all records.
  • 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 LearnPress 4.3.7.

Low priority for now. Upgrade to Unknown LearnPress 4.3.7 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The LearnPress WordPress plugin before 4.3.7 does not gate the `edit` context on one of its REST endpoint behind the `edit_users` capability, allowing unauthenticated visitors to retrieve each returned user's roles, full capabilities map, extra capabilities, locale, and registration date via a crafted request
