What is CVE-2026-40027?
CVE-2026-40027 is a high-severity path traversal vulnerability in abrignoni ALEAPP, published on 8 Apr 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
ALEAPP (Android Logs Events And Protobuf Parser) through 3.4.0 contains a path traversal vulnerability in the NQ_Vault.py artifact parser that uses attacker-controlled file_name_from values from a database directly as the output filename, allowing arbitrary file writes outside the report output directory. An attacker can embed a path traversal payload such as ../../../outside_written.bin in the database to write files to arbitrary locations, potentially achieving code execution by overwriting executable files or configuration.
Weakness: CWE-22
