CVE-2026-109599: Frappe before 15.113.3 Missing Authorization Allows Unauthorized Record Modification

MediumCVSS 5.3 · v4.0—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: 0.19% (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: frappe frappe 15.113.3, 16.25.0.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to frappe frappe 15.113.3, 16.25.0 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

Frappe before 15.113.3 and 16.x before 16.25.0 contains a missing authorization vulnerability in which certain endpoints fail to enforce proper authorization checks. Authenticated users can send requests to these endpoints to modify records beyond what their assigned role permits.
