CVE-2026-55852Network attack vector

Authenticated code execution via unchecked archive members

Published Jul 10, 2026 · Updated Jul 10, 2026

Path traversal in Package Import in Frappe Framework 15 before 15.112.0 and 16 before 16.23.0 allows remote authenticated users to execute code. Package Import extracted an uploaded tar archive without rejecting link entries or verifying that each member path remained inside the site's packages directory. Package Import access and high privileges are required, and successful traversal permits attacker-controlled files and server-side code execution.
