hrms: Exposure of Private Personal Information to an Unauthorized Actor
CVE-2026-126315 is a critical-severity exposure of private personal information to an unauthorized actor vulnerability in hrms from Frappe, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 16.20.1 as the first without the flaw, so updating hrms to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.49% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update hrms to 16.20.1 or a later version.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Frappe HRMS 16.14.0 before 16.20.1 sends product usage events on certain HR transactions without checking the site's telemetry setting, and some events include more detail than needed. During normal use, with no user action, values such as leave type names, claimed amounts and appraisal scores are transmitted even when telemetry is disabled.

The underlying weakness: Exposure of Private Personal Information to an Unauthorized Actor
The product does not properly prevent a person's private, personal information from being accessed by actors who either (1) are not explicitly authorized to access the information or (2) do not have the implicit consent of the person about whom the information is collected.
How developers prevent this class of flaw
- Identify and consult all relevant regulations for personal privacy. An organization may be required to comply with certain federal and state regulations, depending on its location, the type of business it conducts, and the nature of any private data it handles. Regulations may include Safe Harbor Privacy Framework, Gramm-Leach Bliley Act (GLBA), Health Insurance Portability and Accountability Act (HIPAA), General Data Protection Regulation (GDPR), California Consumer Privacy Act (CCPA), and others.
