Relative Path Traversal in Erlang OTP - CVE-2026-47078

Vulnerability identifier: #VU146826

CSH Severity: Medium

CVSS v4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-47078

CWE-ID: CWE-23

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to write arbitrary files outside the intended extraction directory.

The vulnerability exists due to relative path traversal in zip:unzip and zip:extract when processing a crafted zip archive. A remote attacker can supply a specially crafted zip archive to write arbitrary files outside the intended extraction directory.

User interaction is required to open or process the crafted archive.
