Prior to 6.0-alpha.6, when jabsrv or JabRef's built-in HTTP server is enabled, the GET /better-bibtex/cayw endpoint accepts an external command query parameter and CAYWQueryParams.getCommand() passes it through CAYWResource.getCitation() into PushToSublimeText.getCommandLine(). On Unix-like systems, PushToSublimeText combines this untrusted cite-command prefix and citation keys into a string executed through sh -c by ProcessBuilder without shell escaping. A client that can cause a localhost request with application=sublime can inject shell metacharacters and execute operating-system commands as the JabRef user when a valid Sublime Text command path is configured and the victim completes the CAYW selection dialog. The built-in server is disabled by default, so exploitation requires the victim to enable it or run jabsrv. This issue is fixed in version 6.0-alpha.6.","published":"2026-09-17T22:16:59.617","modified":"2026-09-17T22:16:59.617","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/JabRef/jabref/commit/b8663fe58e6c87c3927cdb4eeb1f6934d7c3f1d2","label":"JabRef/jabref@b8663fe"},"references":[{"type":"WEB","url":"https://github.com/JabRef/jabref/commit/b8663fe58e6c87c3927cdb4eeb1f6934d7c3f1d2"},{"type":"WEB","url":"https://github.com/JabRef/jabref/pull/15628"},{"type":"WEB","url":"https://github.com/JabRef/jabref/releases/tag/v6.0-alpha.6"},{"type":"WEB","url":"https://github.com/JabRef/jabref/security/advisories/GHSA-m42c-cw93-p629"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-17T22:16:59.617"}}
