What is CVE-2026-27891?

FacturaScripts, an open-source accounting and invoicing software, contains a vulnerability in the Plugins::add() function that allows for a Zip Slip attack. This occurs due to insufficient validation of file paths in uploaded ZIP archives, enabling an attacker to overwrite sensitive .php files outside the intended plugins directory. The vulnerability arises from the failure to properly sanitize individual file paths within the ZIP structure. Consequently, an attacker can manipulate file names to bypass checks, resulting in arbitrary file write operations and potential remote code execution. This issue has been addressed in version 2026.1 to enhance security.
