File overwrite or deletion via path control
Published Aug 19, 2026 · Updated Aug 19, 2026
Path handling flaws in Cisco Crosswork Planning 7.0.0 through 7.2.0 allow remote attackers to alter files on affected systems via unspecified vectors. Cisco has disclosed only that the affected code performs file-system operations with externally controlled path input; no endpoint, function, or validation failure has been published. Cisco scored the most severe underlying issue as network-reachable with no privileges or user interaction and with integrity and availability impact, so exposed Planning deployments warrant urgent triage even though no public exploitation is known.
