{"cve":"CVE-2026-41206","nvd":{"published":"2026-04-23T02:16:18.533","modified":"2026-10-26T21:10:00.170","status":"Analyzed","description":"PySpector is a static analysis security testing (SAST) Framework engineered for modern Python development workflows. The plugin security validator in PySpector uses AST-based static analysis to prevent dangerous code from being loaded as plugins. Prior to version 0.1.8, the blocklist implemented in `PluginSecurity.validate_plugin_code` is incomplete and can be bypassed using several Python constructs that are not checked. An attacker who can supply a plugin file can achieve arbitrary code execution within the PySpector process when that plugin is installed and executed. Version 0.1.8 fixes the issue.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-184"],"references":["https://github.com/ParzivalHack/PySpector/commit/3c9547157fc07396f22b26b3484a9a91eba98555","https://github.com/ParzivalHack/PySpector/commit/4e279e078c53d760fd321ff9b698d683c65ccb8e","https://github.com/ParzivalHack/PySpector/security/advisories/GHSA-vp22-38m5-r39r","https://github.com/ParzivalHack/PySpector/security/advisories/GHSA-vp22-38m5-r39r"],"products":["parzivalhack:pyspector"],"source":"nvd","synced_at":"2026-10-26T21:38:48.864438205+00:00"},"epss":{"cve":"CVE-2026-41206","score":0.00185,"percentile":0.08001,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-vp22-38m5-r39r","url":"https://osv.dev/vulnerability/GHSA-vp22-38m5-r39r","summary":"PySpector has a Plugin Code Execution Bypass via Incomplete Static Analysis in PluginSecurity.validate_plugin_code","modified":"2026-07-13T16:43:06.959451836Z","packages":[{"ecosystem":"PyPI","name":"pyspector","purl":"pkg:pypi/pyspector","ranges":["<0.1.8"],"fixed":["0.1.8"]}]},{"id":"PYSEC-2026-3031","url":"https://osv.dev/vulnerability/PYSEC-2026-3031","summary":"PySpector has a Plugin Code Execution Bypass via Incomplete Static Analysis in PluginSecurity.validate_plugin_code","modified":"2026-07-13T16:33:12.391765393Z","packages":[{"ecosystem":"PyPI","name":"pyspector","purl":"pkg:pypi/pyspector","ranges":["<0.1.8"],"fixed":["0.1.8"]}]}],"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).
