Source: GCVE Database
Product: golang-1.10

Description

A vulnerability in golang-1.10 on Unix systems allows improper symlink resolution when opening files with os.Root. Specifically, if the final path component is a symbolic link and the path ends with a slash, the code may follow the symlink outside the intended root directory. This can lead to unauthorized file access. Multiple Ubuntu golang package versions are affected. No patch information is provided.

AI-Powered Analysis

Machine-generated threat intelligence

AILast updated: 07/16/2026, 13:20:42 UTC

Technical Analysis

On Unix systems, the golang os.Root file opening function improperly follows symbolic links when the final path component ends with a slash and is a symlink. This behavior allows access to files outside the intended root directory, potentially leading to unauthorized file access. The issue affects numerous Ubuntu golang package versions spanning Ubuntu 14.04 LTS through 26.04 LTS. The CVSS 3.1 vector indicates local attack vector, low attack complexity, low privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability.

Potential Impact

This vulnerability can lead to unauthorized access to files outside the intended root directory, potentially compromising confidentiality, integrity, and availability of the system. An attacker with local access and low privileges can exploit this to access or modify sensitive files, causing significant impact.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch is available, avoid relying on os.Root file opening with paths ending in '/' that may include symbolic links. Monitor vendor advisories for updates and apply official fixes once released.
