Attackers can inject arbitrary radare2 commands through unsanitized symbol name interpolation in the flag rename command, which are then executed when a user runs the idp command against the malicious PDB file, enabling arbitrary OS command execution through radare2's shell execution operator.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.4},"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-78"],"references":["https://blog.calif.io/p/mad-bugs-discovering-a-0-day-in-zero","https://github.com/radareorg/radare2/issues/25730","https://github.com/radareorg/radare2/pull/25731","https://www.vulncheck.com/advisories/radare2-command-injection-via-pdb-parser-symbol-names"],"products":["radare:radare2"],"source":"nvd","synced_at":"2026-10-26T21:38:48.864438205+00:00"},"epss":{"cve":"CVE-2026-40517","score":0.01051,"percentile":0.64061,"date":"2026-10-26"},"kev":null,"osv":[],"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).
