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.","state":0,"publishedAt":"2026-10-23T14:25:00.085+00:00","modifiedAt":"2026-10-23T14:57:32.991+00:00","affected":[{"ecosystem":"Vendor product","name":"infrastructure","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"conda\",\n                    \"product\": \"infrastructure\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 9c0f23857282ff5cf7a6b3ad6bf0dd6f9974be55\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:L","score":9.9,"severity":"CRITICAL"}],"references":["https://github.com/conda/infrastructure/security/advisories/GHSA-pf87-fcg3-wjfh","https://github.com/conda/infrastructure/commit/9c0f23857282ff5cf7a6b3ad6bf0dd6f9974be55"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-53942","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-53942","identifiers":["CVE-2026-53942"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
