CVE-2026-41073

NameCVE-2026-41073
DescriptionRT is an open source, enterprise-grade issue and ticket tracking system. Versions prior to 5.0.10 and 6.0.0 through 6.0.2 contain a spreadsheet (CSV/formula) injection vulnerability. User-controlled data in spreadsheet exports is not sanitized before being written to the output file, which can cause spreadsheet applications to interpret crafted values as formulas or macros when the file is opened. This issue has been fixed in versions 5.0.10 and 6.0.3. If developers are unable to upgrade immediately, they can temporarily work around this issue by avoiding opening exported RT spreadsheet files directly in spreadsheet applications when the data may contain untrusted user input.
