{"cve":"CVE-2026-34172","nvd":{"published":"2026-03-31T15:16:17.507","modified":"2026-07-24T21:10:00.143","status":"Undergoing Analysis","description":"Giskard is an open-source Python library for testing and evaluating agentic systems. Prior to versions 0.3.4 and 1.0.2b1, ChatWorkflow.chat(message) passes its string argument directly as a Jinja2 template source to a non-sandboxed Environment. A developer who passes user input to this method enables full remote code execution via Jinja2 class traversal. The method name chat and parameter name message naturally invite passing user input directly, but the string is silently parsed as a Jinja2 template, not treated as plain text. This issue has been patched in versions 0.3.4 and 1.0.2b1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":7.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-1336"],"references":["https://github.com/Giskard-AI/giskard-oss/security/advisories/GHSA-frv4-x25r-588m","https://github.com/Giskard-AI/giskard-oss/security/advisories/GHSA-frv4-x25r-588m"],"products":["giskard:giskard-agent","giskard:giskard-agents"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-34172","score":0.00635,"percentile":0.50441,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-frv4-x25r-588m","url":"https://osv.dev/vulnerability/GHSA-frv4-x25r-588m","summary":"Giskard Agents have Server-side template injection via ChatWorkflow.chat() using non-sandboxed Jinja2 Environment","modified":"2026-07-13T16:42:41.321155731Z","packages":[{"ecosystem":"PyPI","name":"giskard-agents","purl":"pkg:pypi/giskard-agents","ranges":["<0.3.4"],"fixed":["0.3.4"]},{"ecosystem":"PyPI","name":"giskard-agents","purl":"pkg:pypi/giskard-agents","ranges":[">=1.0.1a1 <1.0.2b1"],"fixed":["1.0.2b1"]}]},{"id":"PYSEC-2026-2487","url":"https://osv.dev/vulnerability/PYSEC-2026-2487","summary":"Giskard Agents have Server-side template injection via ChatWorkflow.chat() using non-sandboxed Jinja2 Environment","modified":"2026-07-13T16:32:37.414509565Z","packages":[{"ecosystem":"PyPI","name":"giskard-agents","purl":"pkg:pypi/giskard-agents","ranges":["<0.3.4",">=1.0.1a1 <1.0.2b1"],"fixed":["0.3.4","1.0.2b1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
