{"id":"CVE-2026-53534","state":"PUBLISHED","title":"JabRef CAYW Sublime Text integration permits operating-system command injection","description":"JabRef is a desktop application for managing BibTeX and BibLaTeX libraries. 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.","publishedAt":"2026-09-17T21:42:47.446Z","updatedAt":"2026-09-24T20:55:23.379Z","severity":{"score":7.5,"label":"High","version":"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","source":"GitHub_M"},"assigner":"GitHub_M","products":["JabRef jabref"],"affected":[{"vendor":"JabRef","product":"jabref","versions":[{"version":"< 6.0-alpha.6","status":"affected"}]}],"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"],"weaknesses":["CWE-78"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/53xxx/CVE-2026-53534.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-53534","state":"PUBLISHED","datePublished":"2026-09-17T21:42:47.446Z","dateUpdated":"2026-09-24T20:55:23.379Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-09T17:30:33.457Z"},"containers":{"cna":{"title":"JabRef CAYW Sublime Text integration permits operating-system command injection","descriptions":[{"lang":"en","value":"JabRef is a desktop application for managing BibTeX and BibLaTeX libraries.
