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.","state":0,"publishedAt":"2026-09-17T21:42:47.446+00:00","modifiedAt":"2026-09-24T20:55:23.379+00:00","affected":[{"ecosystem":"Vendor product","name":"jabref","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"JabRef\",\n                    \"product\": \"jabref\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 6.0-alpha.6\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":7.5,"severity":"HIGH"}],"references":["https://github.com/JabRef/jabref/security/advisories/GHSA-m42c-cw93-p629","https://github.com/JabRef/jabref/pull/15628","https://github.com/JabRef/jabref/commit/b8663fe58e6c87c3927cdb4eeb1f6934d7c3f1d2","https://github.com/JabRef/jabref/releases/tag/v6.0-alpha.6"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-53534","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-53534","identifiers":["CVE-2026-53534"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
