SCA: security update for kimai/kimai (GHSA-3xc2-h5r3-wv3r)

medium Tenable Self-Hosted Container Security Plugin ID 441212

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Kimai is an open-source time tracking application. From version 2.27.0 to before version 2.54.0, any
 ROLE_USER can create a tag with a formula string as its name (e.g. =SUM(54+51)) via POST /api/tags and
 assign it to a timesheet. When an admin exports timesheets to XLSX, ArrayFormatter.formatValue() joins tag
 names with implode() and returns the result unchanged. OpenSpout promotes any =-prefixed string to a
 FormulaCell, writing <f>SUM(54+51)</f> into the XLSX archive. Excel evaluates the formula when the file is
 opened. This issue has been patched in version 2.54.0. (CVE-2026-42267)

Solution

Update the kimai/kimai library and its related packages to version 2.54.0 or later.
