Short explanation
CVE-2026-53942 in Conda Organization Infrastructure is a critical Pwn Request vulnerability within the GitHub Actions update workflow, triggered via privileged SYNC_TOKEN usage. Attackers can control template rendering processes through an unsandboxed Jinja2 environment.
This vulnerability allows low-privileged users to execute malicious templates under a privileged token context, risking data compromise and loss of system integrity.
What should be done?
- Update to the patched commit level
- Follow vendor security advisories

Show the technical text from the sources
Conda Organization Infrastructure is a centralized location for infrastructure codes. Prior to commit 9c0f238, a GitHub Actions Pwn Request vulnerability appears to remain present in conda/conda. The affected workflow is .github/workflows/update.yml. It is triggered by issue_comment events containing @conda-bot render or @conda-bot recreate. For the render path, the workflow obtains the pull request head repository and branch from the PR API, checks out that PR-controlled repository/ref using secrets.SYNC_TOKEN, and then runs conda/actions/template-files@7f6830b1428a9bd47f0b068892c77eae95207037. The external template-files action reads its default configuration and templates from the checked-out working directory. In the confirmed finding, that action uses an unsandboxed Jinja2 environment to render attacker-controlled template content. This creates a Pwn Request chain in which an untrusted PR/comment path can reach template rendering in a privileged token context. This issue has been patched via commit 9c0f238.
