Summary
A path traversal vulnerability exists in Erlang/OTP stdlib's zip functions (zip:unzip/1,2 and zip:extract/1,2) unless the memory option is used. This allows file manipulation outside the target directory.
Risk Assessment
An attacker can read or overwrite arbitrary files on the system, potentially compromising data confidentiality and integrity.
Recommendation
Upgrade Erlang/OTP to version 28.0.1, 27.3.4.1, or 26.2.5.13 depending on your release line.
