CVE-2025-53104Network attack vector

Unauthenticated runner command execution via discussion field interpolation

Published Jul 1, 2025 · Updated Jul 1, 2025

Command injection in Gluestack gluestack-ui before e6b4271 allows remote attackers to execute shell commands through GitHub Discussions. The discussion-to-slack workflow embeds discussion title, body, URL, author, and category values directly into an Ubuntu runner shell block without neutralizing command substitutions. Creating a discussion in a repository that retains the workflow reaches the unauthenticated path, enabling access to runner-held tokens and repository modification.
