CVE-2026-40027: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in abrignoni ALEAPP
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.
AI Analysis
Technical Summary
CVE-2026-40027 is a path traversal vulnerability (CWE-22) in abrignoni ALEAPP affecting versions up to 3.4.0. The vulnerability exists in the NQ_Vault.py artifact parser, which uses file_name_from values from a database without proper sanitization to determine output filenames. An attacker can supply a path traversal payload (e.g., ../../../outside_written.bin) to write files outside the designated output directory. This arbitrary file write can be leveraged to overwrite executable or configuration files, potentially enabling code execution.
Potential Impact
An attacker who can influence the database values controlling output filenames can write files to arbitrary locations on the filesystem. This can lead to overwriting important files, including executables or configuration files, which may result in code execution or system compromise. The CVSS 4.0 score is 8.4 (high severity), reflecting the significant impact of this vulnerability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid processing untrusted or attacker-controlled data with ALEAPP, especially in the NQ_Vault.py parser. Monitor for vendor updates or patches addressing this vulnerability.
