Title
HUSTOJ is Vulnerable to Stored CSV Injection (Formula Injection) in Contest Rank Export
Summary
hustoj is an open source online judge based on PHP/C++/MySQL/Linux for ACM/ICPC and NOIP training. All versions are vulnerable to CSV Injection (Formula Injection) through the contest rank export functionality (contestrank.xls.php and admin/ranklist_export.php). The application fails to sanitize user-supplied input (specifically the "Nickname" field) before exporting it to an .xls file (which renders as an HTML table but is opened by Excel). If a malicious user sets their nickname to an Excel formula when an administrator exports and opens the rank list in Microsoft Excel, the formula will be executed. This can lead to arbitrary command execution (RCE) on the administrator's machine or data exfiltration. A fix was not available at the time of publication.

CVE-2025-67851 (GCVE-0-2025-67851)

Vulnerability from cvelistv5 – Published: 2026-02-03 10:52 – Updated: 2026-02-03 17:02

Title
Moodle: moodle: formula injection allows arbitrary formula execution via unescaped data export
Summary
A flaw was found in moodle. This formula injection vulnerability occurs when data fields are exported without proper escaping. A remote attacker could exploit this by providing malicious data that, when exported and opened in a spreadsheet, allows arbitrary formulas to execute. This can lead to compromised data integrity and unintended operations within the spreadsheet.

CVE-2025-62417 (GCVE-0-2025-62417)

Vulnerability from cvelistv5 – Published: 2025-10-16 18:32 – Updated: 2025-10-17 14:32
VLAI
Title
bagisto - CSV Formula Injection in Create New Product
Summary
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.
Severity

CVE-2025-55745 (GCVE-0-2025-55745)

Vulnerability from cvelistv5 – Published: 2025-08-22 16:14 – Updated: 2025-08-22 20:03

Title
UnoPim Quick Export feature is vulnerable to CSV injection
Summary
UnoPim is an open-source Product Information Management (PIM) system built on the Laravel framework. Versions 0.3.0 and prior are vulnerable to CSV injection, also known as formula injection, in the Quick Export feature. This vulnerability allows attackers to inject malicious content into exported CSV files. When the CSV file is opened in spreadsheet applications such as Microsoft Excel, the malicious input may be interpreted as a formula or command, potentially resulting in the execution of arbitrary code on the victim's device. Successful exploitation can lead to remote code execution, including the establishment of a reverse shell. Users are advised to upgrade to version 0.3.1 or later.
Severity
2.5 (Low)

Mitigation
Implementation

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
Implementation

If a field starts with a formula character, prepend it with a ' (single apostrophe), which prevents Excel from executing the formula.

Mitigation
Architecture and Design

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.
