{"schema":"threatline.record/2","record":{"id":"CVE-2026-53942","aliases":["GHSA-pf87-fcg3-wjfh"],"summary":"Conda Organization Infrastructure: Pwn Request in update workflow allows PR-controlled template rendering with SYNC_TOKEN","details":"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.","categories":["Unclassified"],"product":"infrastructure","vendor":"conda","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-53942","source_modified_at":"2026-10-23T14:57:32.991Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"infrastructure","vendor":"conda","versions":[{"status":"affected","version":"< 9c0f23857282ff5cf7a6b3ad6bf0dd6f9974be55"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/conda/infrastructure/security/advisories/GHSA-pf87-fcg3-wjfh","source_modified_at":"2026-06-18T14:45:52Z","fetched_at":"2026-10-23T20:37:03.234832Z","package":{"name":"infrastructure","ecosystem":null},"range":"<=ad67db1abc2249b1db5dc4b334be82581e359c84"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/conda/infrastructure/security/advisories/GHSA-pf87-fcg3-wjfh","source_modified_at":"2026-06-18T14:45:52Z","fetched_at":"2026-10-23T20:37:03.234832Z","package":{"name":"infrastructure","ecosystem":null},"version":"9c0f23857282ff5cf7a6b3ad6bf0dd6f9974be55"}],"cvss":9.9,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00451,"percentile":0.38281,"score_date":"2026-10-24"},"published_at":"2026-10-23T14:25:00.085Z","modified_at":"2026-10-23T14:57:32.991Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-53942","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T14:57:32.991Z"},{"source":"GitHub Advisory Database","url":"https://github.com/conda/infrastructure/security/advisories/GHSA-pf87-fcg3-wjfh","fetched_at":"2026-10-23T20:37:03.234832Z","source_modified_at":"2026-06-18T14:45:52Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-53942","fetched_at":"2026-10-24T18:03:20.872036Z","source_modified_at":"2026-10-24"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/conda/infrastructure/security/advisories/GHSA-pf87-fcg3-wjfh","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/conda/infrastructure/commit/9c0f23857282ff5cf7a6b3ad6bf0dd6f9974be55","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-23T14:54:29.744728Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-23T14:57:32.991Z","content_hash":"f3bd2058989b8c29aaa9b3947b90d0cb6cfcd42f5e18be89223eb418cae40f97"}}
