Affected:
- frappe hrms: from 16.0.0, fixed in 16.20.1
Fixed versions: 16.20.1.
Conditions (all must be true for the bug to be hit):
- Frappe HRMS versions from 16.0.0 before 16.20.1 (source: https://github.com/frappe/hrms/security/advisories/GHSA-v72r-rg45-x9rh)
- Site has more than one company (source: https://github.com/frappe/hrms/security/advisories/GHSA-v72r-rg45-x9rh)

CISA KEV: CVE-2026-126317 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-126317 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:
