NVD · CVE.org

Joomla Extension - joomlacontenteditor.net - Creation of hidden files and unintended file overwrite via rename function in Joomla Content Editor (JCE) < 2.20.2 - Improper input validation in the file rename functionality allowed an authenticated user with file management permissions to rename files to otherwise invalid names, resulting in the creation of hidden files. The issue also allowed existing files at the destination path to be unintentionally replaced.

Fix

Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
