CVE-2025-54430
Apache Dedupe GitHub Token Exfiltration
Description
dedupe is a python library that uses machine learning to perform fuzzy matching, deduplication and entity resolution quickly on structured data. Before commit 3f61e79, a critical severity vulnerability has been identified within the .github/workflows/benchmark-bot.yml workflow, where a issue_comment can be triggered using the @benchmark body. This workflow is susceptible to exploitation as it checkout the ${{ github.event.issue.number }}, which correspond to the branch of the PR manipulated by potentially malicious actors, and where untrusted code may be executed. Running untrusted code may lead to the exfiltration of GITHUB_TOKEN, which in this workflow has write permissions on most of the scopes - in particular the contents one - and could lead to potential repository takeover. This is fixed by commit 3f61e79.
