Kdenlive before version 26.04.1 permits arbitrary command execution through dangerous proxy parameters embedded in attacker-controlled project files. When a victim opens a malicious .kdenlive project file, the application processes untrusted proxy settings without sufficient validation, enabling code execution with the privileges of the user running Kdenlive. This requires user interaction (opening a file) but poses significant risk in contexts where project files are shared or downloaded from untrusted sources.
KDE Dolphin before 25.12.3 allows sandboxed applications (running under Flatpak or AppArmor confinement) to bypass sandbox restrictions and open arbitrary files outside their containment boundary through the FileManager1 D-Bus protocol implementation. An attacker controlling a sandboxed application can exploit this to access sensitive files or execute scripts with user interaction, circumventing the intended isolation model.
KDE KCoreAddons before version 6.25 contains an improper neutralization of special elements vulnerability in the KShell::quoteArgs() function that fails to safely escape metacharacters and control characters, allowing local attackers with user interaction to inject arbitrary shell commands or terminal control sequences when user input is passed to shell execution contexts. Applications using this method to quote arguments for security-critical operations are affected; exploitation requires local access and user interaction but can achieve arbitrary code execution with user privileges.
KDE Arianna's bookserver before version 26.04.1 allows local attackers to read arbitrary files over socket connections by guessing URLs without authentication, exploiting missing input validation on the bookserver endpoint. The vulnerability requires local access and does not affect confidentiality of other system components; no public exploit code or active exploitation has been identified.
Privilege escalation in KDE Kleopatra before 26.08.0 on Windows allows any local user to assume the operating system privileges of a currently-running Kleopatra process by exploiting a control-flow defect in the KUniqueService single-instance enforcement mechanism. The CVSS 6.9 rating reflects high confidentiality and integrity impact - access to private cryptographic keys and certificates is plausible - but is substantially offset by the local-only attack vector and high complexity (AC:H). No public exploit code has been identified and SSVC confirms exploitation is currently none, with an EPSS of 0.01% placing this in the bottom 2% of CVEs by exploitation likelihood; a vendor patch at 26.08.0 is available via the April 2026 KDE security advisory.
