Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Aqua (github.com/aquaproj/aqua/v2) versions before 2.60.1 are affected. When extracting a tool archive, aqua creates symlinks without checking that their targets stay inside the extraction directory, and a later regular-file entry at the same path follows that symlink. An attacker who supplies a malicious or compromised archive can write content to locations outside the extraction directory, with the privileges of the user running aqua, which could lead to user-level code execution. Upgrade to version 2.60.1 or later.

Written 6 Nov 2026.
