CVE-2026-24039: Horilla's Improper Access Control Allows Employees to Auto-Approve Documents

Noroxi assessment

Priority: Monitor (action score 17/100)

  • 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: 0.26% (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: horilla-opensource horilla 1.5.0.

Low priority for now. Upgrade to horilla-opensource horilla 1.5.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Horilla is a free and open source Human Resource Management System (HRMS). Version 1.4.0 has Improper Access Control, allowing low-privileged employees to self-approve documents they have uploaded. The document-approval UI is intended to be restricted to administrator or high-privilege roles only; however, an insufficient server-side authorization check on the approval endpoint lets a standard employee modify the approval status of their own uploaded document. A successful exploitation allows users with only employee-level permissions to alter application state reserved for administrators. This undermines the integrity of HR processes (for example, acceptance of credentials, certifications, or supporting materials), and may enable submission of unvetted documents. This issue is fixed in version 1.5.0.
