CVE-2026-41073
RT: Spreadsheet downloads vulnerable to CSV/formula injection in Microsoft Excel and similar apps
RT 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.

request-tracker5 vulnerabilities
Aleksander Iwicki discovered that Request Tracker did not properly sanitize the search "Page" URL parameter. A remote attacker could possibly use this issue to conduct a reflected cross-site scripting attack. (CVE-2026-6841)
It was discovered that Request Tracker did not properly sanitize user- controlled data written to spreadsheet exports of search results. A remote attacker could possibly use this issue to conduct a spreadsheet (CSV/formula) injection attack, causing spreadsheet applications to interpret crafted values as formulas or macros when the file is opened. (CVE-2026-41073)
It was discovered that Request Tracker did not properly validate input incorporated into database queries via the entry_aggregator parameter in JSON search. An authenticated user could possibly use this issue to perform SQL injection attacks and read or modify data in the RT database. (CVE-2026-41075)
It was discovered that Request Tracker contained an authentication bypass when configured to authenticate users against an LDAP or Active Directory server. Under certain LDAP server configurations, a remote attacker could possibly use this issue to authenticate as any LDAP-backed RT user without supplying valid credentials. (CVE-2026-41076)
It was discovered that Request Tracker served certain uploaded content inline rather than as an attachment. A remote attacker could possibly use this issue to conduct a cross-site scripting attack. (CVE-2026-44229)
It was discovered that Request Tracker did not properly sanitize input on search-results chart pages. A remote attacker could possibly use this issue to conduct a reflected cross-site scripting attack. (CVE-2026-44230)
Jeroen Gui discovered that Request Tracker did not properly restrict access to the REST 2.0 user collection endpoint. A privileged user could possibly use this issue to obtain authentication credentials belonging to other users, including administrators, resulting in privilege escalation and information disclosure.
