Stored XSS via reparsed commit-link text

Published May 7, 2025 · Updated Aug 20, 2025

Stored XSS in Discourse Code Review before eed3a80 allows remote authenticated users to run JavaScript through malicious commit links. The auto_link_commits method passes substituted text nodes to node.replace, causing previously escaped text to be reparsed as HTML. An account able to post crafted GitHub commit links is required, and the resulting script executes in browsers that view the generated content.
