{"id":"CVE-2026-47752","summary":"Tugtainer has Server-Side Template Injection in notification templates that leads to Remote Code Execution","details":"Tugtainer is a self-hosted app for automating updates of Docker containers. Versions prior to 1.30.2 are vulnerable to Server-Side Template Injection (SSTI) in the notification template feature. The `title_template` and `body_template` fields are rendered using an unsandboxed `jinja2.Environment`, allowing any authenticated user to execute arbitrary OS commands as root inside the container. Version 1.30.2 fixes the issue.","aliases":["GHSA-g2cj-2x47-78vq"],"modified":"2026-07-25T03:56:40.953506253Z","published":"2026-07-23T16:57:54.967Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-1336"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47752.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47752.json"},{"type":"ADVISORY","url":"https://github.com/Quenary/tugtainer/security/advisories/GHSA-g2cj-2x47-78vq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47752"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/quenary/tugtainer","events":[{"introduced":"0"},{"fixed":"eaecc5566625b1f502b1851552382c3f71a1068a"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.30.2"}],"source":"AFFECTED_FIELD"}}],"versions":["v1.30.1","v1.30.0","v1.29.1","v1.29.0","v1.28.3","v1.28.2","v1.28.1","v1.28.0","v1.27.0","v1.26.0","v1.25.1","v1.25.0","v1.24.1","v1.24.0","v1.23.1","v1.23.0","v1.22.0","v1.21.1","v1.21.0","v1.20.0","v1.19.0","v1.18.0","v1.17.5","v1.17.4","v1.17.3","v1.17.2","v1.17.1","v1.17.0","v1.16.1","v1.16.0","v1.15.2","v1.15.1","v1.15.0","v1.14.4","v1.14.3","v1.14.2","v1.14.1","v1.14.0","v1.13.1","v1.13.0","v1.12.2","v1.12.1","v1.12.0","v1.11.0","v1.10.0","v1.9.0","v1.8.0","v1.7.1","v1.7.0","v1.6.0","v1.5.3","v1.5.2","v1.5.1","v1.5.0","v1.4.2","v1.4.1","v1.4.0","v1.3.0","v1.2.3","v1.2.2","v1.2.1","v1.2.0","v1.1.6","v1.1.5","v1.1.4","v1.1.3","v1.1.2","v1.1.1","v1.1.0","v1.0.3","v1.0.2","v1.0.1","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-47752.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
