Summary
request-tracker5 vulnerabilities
Details
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. (CVE-2026-44231)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
