CVE-2026-8274: Path Traversal in npitre cramfs-tools
CVE-2026-8274 is a path traversal vulnerability in the do_directory function of cramfsck.c within npitre cramfs-tools versions up to 2.1. This vulnerability allows local attackers to manipulate directory handling to perform path traversal. Exploitation requires local access and no user interaction. A patch is available in version 2.2 that addresses this issue.
AI Analysis
Technical Summary
The vulnerability exists in the do_directory function of the cramfsck.c file in npitre cramfs-tools up to version 2.1. It allows an attacker with local access to perform path traversal attacks by manipulating directory handling. This could potentially lead to unauthorized file system access or modification within the constraints of local privileges. The issue is fixed in version 2.2 by a patch identified as 2fc492747115b24d8a07eddd27a2d45229cb273c.
Potential Impact
The vulnerability enables local attackers to perform path traversal, which may allow them to access or modify files outside the intended directory scope. Since the attack requires local access and low privileges, the impact is limited to local users. The CVSS score of 4.8 (medium severity) reflects this limited attack vector and impact scope.
Mitigation Recommendations
Upgrade npitre cramfs-tools to version 2.2, which contains the official patch (commit 2fc492747115b24d8a07eddd27a2d45229cb273c) that fixes this path traversal vulnerability. No other mitigations are indicated or necessary once the upgrade is applied.
