Descrição técnica

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.

——9CSV formula injection vulnerability in the export functionality of the Coupa Supplier Portal SaaS platform. The vulnerability arises because certain user-controlled data, such as event names or templates within the Tenders module, are not properly validated or sanitised before being included in CSV files generated by the application. An attacker with low privileges can input specially crafted values that begin with characters interpreted as formulas by spreadsheet applications. When a victim downloads and opens the generated file in a compatible client, the content may be interpreted as a formula, potentially leading to unauthorised actions such as the execution of commands via mechanisms such as DDE, access to information, or interaction with system resources under the victim’s context.3d CVE-2026-1166484.1 MÉD

——3AzuraCast before 0.24.0 contains a stored CSV formula injection vulnerability that allows station users with Media permission to persist formula-prefixed metadata via bulk media import. Attackers can import crafted titles, artists, or custom fields through /api/station/{station_id}/files/bulk so formulas evaluate when other users open exported CSVs in spreadsheets.4d CVE-2026-671877.1 ALT

——2Ninja Forms plugin for WordPress before 3.15.4 contains an incomplete server-side validation vulnerability that allows unauthenticated attackers to submit arbitrary values to Checkbox List, Multi-Select List, Image List, Country, and State fields because NF_Abstracts_List falls through to a validate() method that only checks required-field presence. Attackers can submit crafted formula payloads through the unauthenticated nf_ajax_submit endpoint that bypass CSV escaping applied only to Textbox and Textarea fields, resulting in CSV injection when an administrator downloads and opens the exported submissions file.2d CVE-2026-102799—
