How to Fix GHSA-pjx8-984p-7p3x

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

friendsofsymfony/user-bundle fixed: 1.3.5 
Upgrade friendsofsymfony/user-bundle to 1.3.5
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 friendsofsymfony/user-bundle

How to Check if You Are Affected

To determine whether your application is affected by GHSA-pjx8-984p-7p3x, inspect your project dependencies for Friendsofsymfony/user bundle:

inspect dependencies for friendsofsymfony/user-bundle

Analyze the terminal output to locate any version of Friendsofsymfony/user bundle in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.3.5), your application is affected.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-331: Insufficient Entropy, where the product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others. In Friendsofsymfony/user bundle, 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

### Description Because of the usage of base_convert which looses precision for large inputs, the entropy of tokens generated by FOSUserBundle for the email confirmation and password resetting is lost. This makes these tokens much less random than they are expected to be, and so not cryptographically safe. ### Resolution The token generation logic used in the 2.0.x branch based on base64 encoding has been backported. This changes the range of characters used in the token. Any route placeholder expected to match a token generated by FOSUserBundle must be updated to allow dashes, which are not allowed by \w in regexes. A \w+ requirement should so become [\w\-]+.
