CVE-2026-28808

Description

A flaw was found in Erlang OTP (inets modules). A remote unauthenticated attacker could exploit an incorrect authorization vulnerability when CGI (Common Gateway Interface) scripts are served via script_alias. This vulnerability arises from a path mismatch where access controls are evaluated against a different path than the script's execution path. This allows unauthorized access to CGI scripts intended to be protected by directory rules, potentially leading to information disclosure or the execution of unauthorized scripts.

Mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.
