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."}, {"lang": "es", "value": "dedupe es una librer\u00eda de Python que utiliza aprendizaje autom\u00e1tico para realizar coincidencias difusas, deduplicaci\u00f3n y resoluci\u00f3n de entidades r\u00e1pidamente en datos estructurados.
