{"identifier":"CVE-2026-41526","cve":{"id":"CVE-2026-41526","description":"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.","published":"2026-04-28T08:16:01.647000+00:00","modified":"2026-10-26T21:10:00.170000+00:00","status":"Analyzed","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:L","cvss_version":"3.1","affected":[{"criteria":"cpe:2.3:a:kde:kcoreaddons:*:*:*:*:*:*:*:*","versionStartIncluding":"","versionStartExcluding":"","versionEndIncluding":"","versionEndExcluding":"6.25.0"}],"weaknesses":["CWE-150"],"references":[{"url":"https://github.com/KDE/kcoreaddons/blob/50d360736c399502fedf203e95482b0d0e5a3ea2/src/lib/util/kshell.h#L168","source":"cve@mitre.org","tags":["Product"]},{"url":"https://github.com/KDE/kcoreaddons/blob/50d360736c399502fedf203e95482b0d0e5a3ea2/src/lib/util/kshell.h#L43-L49","source":"cve@mitre.org","tags":["Product"]},{"url":"https://github.com/KDE/kcoreaddons/releases/tag/v6.25.0","source":"cve@mitre.org","tags":["Release Notes"]},{"url":"https://invent.kde.org/frameworks/kcoreaddons/","source":"cve@mitre.org","tags":["Product"]},{"url":"https://kde.org/info/security/advisory-20260427-1.txt","source":"cve@mitre.org","tags":["Vendor Advisory"]}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"cve@mitre.org","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:L","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"LOW"},"exploitabilityScore":1.0,"impactScore":5.5},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","baseScore":7.8,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":5.9}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-04-28T13:00:44.980535Z","id":"CVE-2026-41526","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:kde:kcoreaddons:*:*:*:*:*:*:*:*","versionEndExcluding":"6.25.0","matchCriteriaId":"B9E0D1D8-4EAB-491A-8678-D3183FA933CB"}]}]}],"source":"nvd","retrieved_at":"2026-10-28T10:19:44.974275+00:00","exploited":false,"kev_stale":false,"products":["kde / kcoreaddons"],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.0017,"percentile":0.06404,"date":"2026-10-28","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"github.com","source_url":"https://github.com/KDE/kcoreaddons/blob/50d360736c399502fedf203e95482b0d0e5a3ea2/src/lib/util/kshell.h#L168","investigate_url":"https://investigate.aeglixmind.com/#github.com"},{"domain":"invent.kde.org","source_url":"https://invent.kde.org/frameworks/kcoreaddons/","investigate_url":"https://investigate.aeglixmind.com/#invent.kde.org"},{"domain":"kde.org","source_url":"https://kde.org/info/security/advisory-20260427-1.txt","investigate_url":"https://investigate.aeglixmind.com/#kde.org"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-41526","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-41526","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-41526","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
