How to Fix GHSA-cv5c-2qv5-w2m2

To remediate this vulnerability, upgrade all affected Passbolt/passbolt api dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

passbolt/passbolt_api fixed: 2.7.0 
Upgrade passbolt/passbolt_api to 2.7.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for passbolt/passbolt_api

How to Check if You Are Affected

To determine whether your application is affected by GHSA-cv5c-2qv5-w2m2, inspect your project dependencies for Passbolt/passbolt api:

inspect dependencies for passbolt/passbolt_api

Analyze the terminal output to locate any version of Passbolt/passbolt api in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.7.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Passbolt/passbolt api, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Passbolt provides a way for system administrators to generate a PGP key for the server during installation. The wizard requests a username, an e-mail address and an optional comment. No escaping or verification is done by Passbolt, effectively allowing a user to inject bash code. The impact is very high, but the probability is very low given that this vulnerability can only be exploited during Passbolt’s installation stage.
