{"id":"CVE-2026-67195","summary":"Perspective 5.0.0 RCE via eval() Expression Injection","details":"Perspective 5.0.0 contains a remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary operating system commands by submitting crafted expression strings to the PolarsVirtualServer backend, which passes client-supplied input directly to Python's eval() with only __builtins__={} cleared. Attackers can exploit Python object attribute traversal through the interpreter's loaded class list to reach subprocess.Popen via a TableValidateExprReq or TableMakeViewReq protobuf message, achieving arbitrary command execution in the Perspective host process.","modified":"2026-08-06T03:48:34.489703679Z","published":"2026-08-04T14:03:17.891Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67195.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-95"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67195.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67195"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/perspective-rce-via-eval-expression-injection"},{"type":"PACKAGE","url":"https://github.com/perspective-dev/perspective"},{"type":"EVIDENCE","url":"https://christbowel.com/blog/perspective-5-0-0-five-cves/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/perspective-dev/perspective","events":[{"introduced":"0"},{"last_affected":"f0a4f5b327942c64edbc53b60655007b147ff6cc"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"5.0.0"}]}}],"versions":["v5.0.0","v4.5.2","v4.5.1","v4.5.0","v4.4.1","v4.4.0","v4.3.0","v4.2.0","v4.1.1","v4.1.0","v4.0.1","v4.0.0","v3.8.0","v3.7.4","v3.7.3","v3.7.2","v3.7.1","v3.7.0","v3.6.1","v3.6.0","v3.5.1","v3.5.0","v3.4.3","v3.4.2","v3.4.1","v3.4.0","v3.3.4","v3.3.3","v3.3.2","v3.3.1","v3.3.0","v3.2.1","v3.2.0","v3.1.8","v3.1.7","v3.1.6","v3.1.5","v3.1.4","v3.1.3","v3.1.2","v3.1.1","v3.1.0","v3.0.3","v3.0.2","v3.0.1","v3.0.0","v2.10.1","v2.10.0","v2.9.0","v2.8.1","v2.8.0","v2.7.1","v2.7.0","v2.6.1","v2.6.0","v2.5.2","v2.5.1","v2.5.0","v2.4.0","v2.3.2","v2.3.1","v2.3.0","v2.2.1","v2.2.0","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.1.0","v2.0.1","v2.0.0","v1.9.4","v1.9.3","v1.9.2","v1.9.1","v1.9.0","v1.8.1","v1.8.0","v1.7.2","v1.7.1","v1.7.0","v1.6.5","v1.6.4","v1.6.3","v1.6.2","v1.6.1","v1.6.0","v1.5.1","v1.5.0","v1.4.1","v1.4.0","v1.3.13","v1.3.12","v1.3.11","v1.3.10","v1.3.9","v1.3.8","v1.3.7","v1.3.6","v1.3.5","v1.3.4","v1.3.3","v1.3.2","v1.3.1","v1.3.0","v1.2.0","v1.1.1","v1.1.0","v1.0.8","v1.0.6","v1.0.7","v1.0.5","v1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0.0-rc.2","v1.0.0","v1.0.0-rc.1","v1.0.0-rc.0","v0.10.3","v0.10.2","v0.10.1","v0.10.0","v0.9.0","v0.8.3","v0.8.2","v0.8.1","v0.8.0","v0.7.0","v0.6.2","v0.6.1","v0.6.0","v0.5.6","v0.5.5","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.8","v0.4.7","v0.4.6","v0.4.5","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.4.0-rc.6","v0.4.0-rc.5","v0.4.0-rc.4","v0.4.0-rc.3","v0.4.0-rc.2","v0.4.0-rc.1","v0.3.9","v0.3.8","v0.3.7","v0.3.6","v0.3.5","v0.3.4","v0.3.3","v0.3.2","v0.3.1","v0.3.0","v0.3.0-rc.4","v0.3.0-rc.3","v0.3.0-rc.2","v0.3.0-rc.1","v0.2.23","v0.2.22","v0.2.21","v0.2.20","v0.2.19","v0.2.18","v0.2.17","v0.2.16","v0.2.15","v0.2.14","v0.2.13","v0.2.12","v0.2.11","v0.2.10","v0.2.9","v0.2.8","v0.2.7","v0.2.6","v0.2.5","v0.2.4","v0.2.3","v0.2.2","v0.2.1","v0.2.0","v0.2.0-beta.3","0.2.0-beta.3","v0.2.0-beta.2","v0.2.0-beta.1","v0.1.18","v0.1.17","v0.1.16","v0.1.15","v0.1.14","v0.1.13","v0.1.12","v0.1.11","v0.1.10","v0.1.9","v0.1.8","v0.1.7","v0.1.6","v0.1.5","v0.1.4","v0.1.3","v0.1.2","v0.1.1","v0.1.0","v0.0.2","v0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-67195.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
