SUPEE-11346

SUPEE-11346 is security patch for Magento 1 released on June 22, 2020 to close PHP Object Injection and Stored cross-site scripting vulnerabilities (CVE-2020-9664 and CVE-2020-9665). Both vulnerabilities are only exploitable by authenticated admin user with access to Backend.

There were no new M1 version released by Magento/Adobe for this update, so the latest Magento 1.9.4.5 should be patched with SUPEE-11346.
OpenMage LTS released v19.4.4 and v20.0.0 with this patch included.

Note: Install this and any other missing patches with our Magento patch installation service or upgrade to OpenMage LTS v19.4.15 (released on August 26, 2021).

What is changed with SUPEE-11346

It is probably the smallest patch for M1. Known issues are not expected with SUPEE-11346 as it changes just a three lines of code in 3 files (filtered user input, sanitized unserialize() call and protected `entity_type_id` on attribute save):
