CWE-88Published: September 19, 2023· Updated: Jun 17, 2026

9.1

CVSS v3.1

Official Description

Versions of the package blamer before 1.0.4 are vulnerable to Arbitrary Argument Injection via the blameByFile() API. The library does not sanitize for user input or validate the given file path conforms to a specific schema, nor does it properly pass command-line flags to the git binary using the double-dash POSIX characters (--) to communicate the end of options.

Risk Analysis

The blamer package is susceptible to arbitrary argument injection because it fails to properly sanitize inputs or use POSIX double-dash separators when calling the git binary. This critical flaw allows remote attackers to manipulate command-line arguments, potentially leading to unauthorized system actions.

There is no known public exploit for this issue, and it is not in the CISA KEV catalog.

Recommended Action

Users should update the blamer package to version 1.0.4 or higher.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2023-26143 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.1.
