Bagisto is an open source laravel eCommerce platform.
CVSS 7.1 High EPSS 0.4% · p32
Should you act?
Normal patch cycle
No exploitation signal; fix it in your next routine update if you are affected. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Not in CISA KEV, but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.4%, percentile 32: FIRST’s model estimates a 0.4% chance of exploitation activity in the next 30 days, higher than 32% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs local access needed. Lower urgency for most teams unless an attacker could already run code on the machine.
- Only applies if your dependency tree includes
bagisto/bagisto(Composer (PHP)) <= 2.3.7, fixed in 2.3.8. Check your lockfile, including transitive dependencies.
What it is
Bagisto is an open source laravel eCommerce platform. When product data that begins with a spreadsheet formula character (for example =, +, -, or @) is accepted and later exported or saved into a CSV and opened in spreadsheet software, the spreadsheet will interpret that cell as a formula. This allows an attacker to supply a CSV field (e.g., product name) that contains a formula which may be evaluated by a victim’s spreadsheet application — potentially leading to data exfiltration and remote command execution (via older Excel exploits / OLE/cmd constructs or Excel macros). This vulnerability is fixed in 2.3.8.
From the GitHub advisory
Summary When product data that begins with a spreadsheet formula character (for example =, +, -, or @) is accepted and later exported or saved into a CSV and opened in spreadsheet software, the spreadsheet will interpret that cell as a formula. This allows an attacker to supply a CSV field (e.g., product name) that contains a formula which may be evaluated by a victim’s spreadsheet application — potentially leading to data exfiltration and remote command execution (via older Excel exploits / OLE/cmd constructs or Excel macros).
Details Spreadsheet applications treat cell text that begins with characters =, +, -, @ as formulas. If unescaped, spreadsheet will interpret and evaluate the content when the file is opened. The application fails to neutralize/escape leading formula characters when generating CSV or when accepting CSV import fields for display/export.
PoC Insert CSV formula to the product name field, and save the changes. Export it to CSV file, open it and the calc.exe will be executed. Other CSV export functions are affected as well. http://127.0.0.1/admin/catalog/products/edit/1
Impact Data exfiltration: Using spreadsheet functions (e.g., WEBSERVICE, HYPERLINK, or concatenation to create requests) on victims' machines that make network calls. Remote command execution: In some historical cases, specially crafted formulas and older Excel behaviors can lead to RCE. Modern Excel hardens many of these, but risk remains depending on environment.
Weakness type: CWE-1236.
