This parsing does not adequately handle metacharacters, leading to an escape from the shell. All applications relying on this method in a security-critical path to handle user input are affected and could be exploited. In particular, because sendInput() sends a string to a terminal, a control character such as \\x01 can be used during injection."}], "lastModified": "2026-05-05T17:25:06.683", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:kde:kcoreaddons:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B9E0D1D8-4EAB-491A-8678-D3183FA933CB", "versionEndExcluding": "6.25.0"}], "operator": "OR"}]}], "sourceIdentifier": "cve@mitre.org"}
