CVE-2026-41530

Misplaced file extraction via crafted archive filename

Published May 12, 2026 · Updated May 12, 2026

Path traversal in Chitora Soft Lhaz+ 3.6.3 and earlier allows local users to extract archive contents to an unexpected folder. The automatic folder creation feature derives the extraction directory from the archive filename; for certain crafted names, it creates no same-name folder and instead selects the archive parent directory. Exploitation requires automatic folder creation to be enabled and a user to extract the crafted archive, allowing files to be written outside the intended destination.
