How to Fix GHSA-2m5g-8xpw-42vp

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

cartalyst/sentry fixed: 2.1.7 
Upgrade cartalyst/sentry to 2.1.7
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 cartalyst/sentry

How to Check if You Are Affected

To determine whether your application is affected by GHSA-2m5g-8xpw-42vp, inspect your project dependencies for Cartalyst/sentry:

inspect dependencies for cartalyst/sentry

Analyze the terminal output to locate any version of Cartalyst/sentry in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.1.7), 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 General Security Weakness. In Cartalyst/sentry, 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

OpenCFP, an open-source conference talk submission system written in PHP, contains a security vulnerability in its third-party authentication framework, Sentry, developed by Cartalyst. The vulnerability stems from how Sentry handles password reset checks. Users lacking a password reset token stored in the database default to having NULL in the reset_password_code column. Exploiting this flaw could allow unauthorized manipulation of any OpenCFP user's password, particularly those without an unused password reset token. Although successful login still requires correlating the numeric user ID with an email address, the identification of likely organizers (users 1-5) may facilitate this process.
