# conda-forge status site renders build logs as raw HTML

Two React components on the conda-forge status website inject externally sourced strings, such as build logs and tracebacks, into the page with dangerouslySetInnerHTML and no sanitization. An attacker who can get markup into those logs, for example through a crafted upstream package or patch output, can run script in the browser of a visitor to the site.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

conda-forge is a GitHub organization containing repositories of conda recipes. In commits 85748ad2368a and prior, two React components render externally-sourced strings directly as HTML using dangerouslySetInnerHTML, with no sanitization (the project has no DOMPurify or equivalent dependency). JSON files are produced automatically by the conda-forge autotick bot (regro/cf-scripts) while it processes every conda-forge feedstock and its upstream source artifacts. The error/status strings embed raw output captured from those processes (build logs, patch output, tracebacks). The website renders them verbatim as HTML. At time of publication, there are no publicly available patches.
