CVE-2020-26283: 
Linux Alpine vulnerability analysis and mitigation

CVE-2020-26283 affects go-ipfs, an open-source golang implementation of IPFS (InterPlanetary File System), which is a global, versioned, peer-to-peer filesystem. The vulnerability was discovered in versions before 0.8.0, where control characters were not properly escaped from console output. This issue was disclosed on March 24, 2021, and has been fixed in version 0.8.0 (GitHub Advisory).

The vulnerability stems from the lack of proper escaping of control characters in the console output functionality. When displaying user-controlled input in the CLI, the application failed to properly escape non-printable characters and control sequences. This could allow malicious input to manipulate the console output. The issue has been assigned a CVSS v3.1 base score of 6.8 MEDIUM by GitHub, Inc., with a vector string of CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:N/I:H/A:N (NVD).

The vulnerability could allow an attacker to hide input from the user, potentially leading to users taking unknown, malicious actions. By manipulating the console output through unescaped control characters, attackers could potentially obscure or manipulate the display of important information (GitHub Advisory).

The vulnerability has been patched in go-ipfs version 0.8.0. The fix involves implementing proper escaping of non-printable characters and control sequences in console output. Users are advised to upgrade to version 0.8.0 or later to address this security issue. The patch was implemented through pull request #7831, which adds functionality to escape non-printable characters in user output (GitHub PR).
