Executive Summary

This vulnerability in Gitea's notification API occurs because it does not re-check repository access permissions when providing notification details. As a result, if a user's access to a private repository is revoked, they may still be able to see issue and pull request titles from notifications they received before losing access.

Impact Analysis

The vulnerability can lead to unauthorized disclosure of information, as users who no longer have access to a private repository might still view sensitive issue and pull request titles. This could expose confidential project details or development activities to unintended parties.
