{"schema":"threatline.record/2","record":{"id":"CVE-2026-55154","aliases":["GHSA-xrwp-2gph-985x"],"summary":"EspoCRM: CSV/Formula Injection sanitizer bypass via leading whitespace/control characters in export","details":"EspoCRM is an open source customer relationship management application. Prior to 9.3.9, application/Espo/Tools/Export/Format/Csv/Processor.php, application/Espo/Tools/Export/Format/Xlsx/OpenSpoutProcessor.php, and application/Espo/Tools/Export/Format/Xlsx/PhpSpreadsheetProcessor.php inspect only the first byte in sanitizeCellValue(). An authenticated low-privileged user can store a free-text value whose formula trigger is preceded by whitespace or a control character, causing CSV or XLSX export to omit the leading single-quote formula-neutralization prefix. When a privileged user opens the exported file and accepts applicable spreadsheet security prompts, spreadsheet software can ignore the whitespace or control-character prefix and evaluate the cell as a formula, permitting outbound data disclosure and, on legacy configurations with DDE enabled, command execution. This issue is fixed in version 9.3.9.","categories":["Unclassified"],"product":"espocrm","vendor":"espocrm","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-55154","source_modified_at":"2026-10-16T17:13:56.910Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"espocrm","vendor":"espocrm","versions":[{"status":"affected","version":"< 9.3.9"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/espocrm/espocrm/security/advisories/GHSA-xrwp-2gph-985x","source_modified_at":"2026-07-14T09:09:22Z","fetched_at":"2026-10-23T18:58:35.272684Z","package":{"ecosystem":"composer","name":"espocrm/espocrm"},"range":"<= 9.3.8"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/espocrm/espocrm/security/advisories/GHSA-xrwp-2gph-985x","source_modified_at":"2026-07-14T09:09:22Z","fetched_at":"2026-10-23T18:58:35.272684Z","package":{"ecosystem":"composer","name":"espocrm/espocrm"},"version":"9.3.9"}],"cvss":5.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.0021,"percentile":0.10623,"score_date":"2026-10-23"},"published_at":"2026-10-15T14:49:15.584Z","modified_at":"2026-10-16T17:13:56.910Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-55154","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T17:13:56.910Z"},{"source":"GitHub Advisory Database","url":"https://github.com/espocrm/espocrm/security/advisories/GHSA-xrwp-2gph-985x","fetched_at":"2026-10-23T18:58:35.272684Z","source_modified_at":"2026-07-14T09:09:22Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-55154","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/espocrm/espocrm/security/advisories/GHSA-xrwp-2gph-985x","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/espocrm/espocrm/commit/f209248efd0d63bc8f7906cb96c07020a758eead","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/espocrm/espocrm/releases/tag/9.3.9","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-15T20:24:34.482538Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-16T17:13:56.910Z","content_hash":"482027a6ebede054c2b87502a92fd889f9f1aebacadd3d0d450dbf27ebe9fff8"}}
