| kevinpapst/kimai2 | composer | < 1.14.1 | 1.14.1 |
The vulnerability stems from improper neutralization of formula elements in CSV exports. The patch commit shows changes in AbstractSpreadsheetRenderer where DDE payload sanitization was added. Prior to 1.14.1, the export functionality didn't escape formula-initiating characters in user-controlled fields like description. The addRowToSheet method (or similar CSV rendering logic) would be the point where untrusted data enters CSV output without sanitization, making it the vulnerable function. The high confidence comes from: 1) CWE-1236 mapping to CSV formula injection, 2) patch focusing on spreadsheet rendering, and 3) vulnerability description implicating CSV export of timesheet descriptions.
