GHSA-H77M-QRJ7-JXCW
Vulnerability from github – Published: 2026-06-26 23:03 – Updated: 2026-06-26 23:03Impact
Form submission values were not neutralized for spreadsheet formula characters when exported to CSV. A submission containing a value beginning with a formula trigger character (e.g. = , + , - , @ ) could be interpreted as a live formula when a Control Panel user opens the export in a spreadsheet application. Form submissions can come from unauthenticated front-end visitors, so the malicious value can be supplied by an anonymous user and is later triggered by an editor opening the export.
Exploitation affects the spreadsheet application used to open the export, not the Statamic application or server; the data at risk is the form submission data the exporting user is already authorized to view.
Patches
This has been fixed in 5.73.24 and 6.20.1.

GHSA-H7VQ-5QGW-JWWQ
Vulnerability from github – Published: 2021-10-18 19:04 – Updated: 2021-10-18 19:11Impact
In some circumstances, it was possible to export data in CSV format that could trigger a payload in old versions of Excel.
If you are accepting user input from untrusted sources and will be exporting that data in CSV format from element index pages and there is a chance users will open that on old versions of Excel, then you should update.
Patches
This has been patched in Craft 3.7.14.

}
Mitigation
When generating CSV output, ensure that formula-sensitive metacharacters are effectively escaped or removed from all data before storage in the resultant CSV. Risky characters include '=' (equal), '+' (plus), '-' (minus), and '@' (at).
Mitigation
If a field starts with a formula character, prepend it with a ' (single apostrophe), which prevents Excel from executing the formula.
Mitigation
Certain implementations of spreadsheet software might disallow formulas from executing if the file is untrusted, or if the file is not authored by the current user.
No CAPEC attack patterns related to this CWE.
