Title

Gopeed through 2.0.0-beta.3 Arbitrary File Write via Path Traversal

Summary

Gopeed through 2.0.0-beta.3 contains a path traversal vulnerability in archive extraction that allows attackers to write arbitrary files outside the extraction directory. Attackers can craft malicious archives with entries containing directory traversal sequences that bypass validation, enabling file write operations when users download and extract archives with AutoExtract enabled.

Severity

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
