{"id":"CVE-2026-41526","details":"In KDE KCoreAddons before 6.25, KShell::quoteArgs is intended to safely quote arguments so that they can be passed to a shell command. 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.","modified":"2026-07-15T01:49:13.749296335Z","published":"2026-04-28T00:00:00Z","related":["openSUSE-SU-2026:20701-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41526.json","cna_assigner":"mitre","cwe_ids":["CWE-150"]},"references":[{"type":"WEB","url":"https://github.com/KDE/kcoreaddons/blob/50d360736c399502fedf203e95482b0d0e5a3ea2/src/lib/util/kshell.h#L168"},{"type":"WEB","url":"https://github.com/KDE/kcoreaddons/blob/50d360736c399502fedf203e95482b0d0e5a3ea2/src/lib/util/kshell.h#L43-L49"},{"type":"WEB","url":"https://github.com/KDE/kcoreaddons/releases/tag/v6.25.0"},{"type":"WEB","url":"https://invent.kde.org/frameworks/kcoreaddons/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41526.json"},{"type":"ADVISORY","url":"https://kde.org/info/security/advisory-20260427-1.txt"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41526"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kde/kcoreaddons","events":[{"introduced":"0"},{"fixed":"447250fb061d6a866eeef9ae3c21b627244b198a"}],"database_specific":{"source":["AFFECTED_FIELD","CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:kde:kcoreaddons:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"6.25"},{"fixed":"6.25.0"}]}}],"versions":["v6.25.0-rc1","v6.24.0-rc1","v6.24.0","v6.23.0-rc1","v6.23.0","v6.22.0-rc1","v6.22.0","v6.21.0-rc1","v6.21.0","v6.20.0-rc1","v6.20.0","v6.19.0-rc1","v6.19.0","v6.18.0-rc1","v6.18.0","v6.17.0-rc1","v6.17.0","v6.16.0-rc1","v6.15.0-rc1","v6.15.0","v6.14.0-rc1","v6.14.0","v6.13.0-rc1","v6.13.0","v6.12.0-rc1","v6.12.0","v6.11.0-rc1","v6.11.0","v6.10.0-rc1","v6.10.0","v6.9.0-rc1","v6.9.0","v6.8.0-rc1","v6.8.0","v6.7.0-rc1","v6.7.0","v6.6.0-rc1","v6.6.0","v6.5.0-rc1","v6.5.0","v6.4.0-rc1","v6.4.0","v6.3.0-rc1","v6.3.0","v6.2.0","v6.1.0","v6.0.0","v5.249.0","v5.248.0","v5.247.0","v5.246.0","v5.245.0","v5.102.0-rc1","v5.102.0","v5.101.0-rc1","v5.101.0","v5.100.0-rc1","v5.100.0","v5.71.0-rc1","v5.58.0-rc2","v4.100.0-rc1","v4.98.0","v4.97.0","v4.96.0","v4.95.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-41526.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:L"}]}
