This is not desired behavior, and tar(1) rejects such extractions, but ocaml-tar decompresses it anyway. The impact is that it allows arbitrary file writes outside of the desired extraction directory (to an attacker that can reach a tar decompression endpoint)."},"products":[{"@id":"cpe:2.3:a:n\\/a:n\\/a:n\\/a:*:*:*:*:*:*:*","identifiers":{"cpe23":"cpe:2.3:a:n\\/a:n\\/a:n\\/a:*:*:*:*:*:*:*"}}],"status":"affected","action_statement":"No fixed version is published yet; monitor the upstream advisory.","timestamp":"2026-06-16T14:02:18.195Z"}]}
