Vulnerability from cvelistv5 – Published: 2026-07-21 20:13 – Updated: 2026-07-30 17:30

Title

FileGator privilege escalation

Summary

FileGator accepts arbitrary Unix permission values via the '/chmoditems' API endpoint and passes the value directly to PHP's native 'chmod()' function through 'octdec()' conversion, with no validation. This allows an authenticated user with 'chmod' permission to upgrade their privileges to root.

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.
