CVE-2026-25509: CI4MS Vulnerable to User Email Enumeration via Password Reset Flow

MediumCVSS 5.3 · v3.1—No exploit Fix available

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: 0.38% (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: ci4-cms-erp ci4ms 0.28.5.0.

Low priority for now. Upgrade to ci4-cms-erp ci4ms 0.28.5.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

CI4MS is a CodeIgniter 4-based CMS skeleton that delivers a production-ready, modular architecture with RBAC authorization and theme support. Prior to version 0.28.5.0, the authentication implementation in CI4MS is vulnerable to email enumeration. An unauthenticated attacker can determine whether an email address is registered in the system by analyzing the application's response during the password reset process. This issue has been patched in version 0.28.5.0.
