Lifecycle Timeline
2DescriptionGitHub Advisory
RT is an open source, enterprise-grade issue and ticket tracking system. Versions 5.0.0 through 5.0.9 and 6.0.0 through 6.0.2 contain an SQL injection vulnerability. An authenticated user can craft input that is incorporated into database queries without proper validation, potentially allowing them to read or modify data in the RT database. 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 restricting RT account access to trusted users.
AnalysisAI
Authenticated SQL injection in Best Practical's Request Tracker (RT) ticketing system affects versions 5.0.0-5.0.9 and 6.0.0-6.0.2 via the entry_aggregator parameter in the JSON search endpoint, allowing any logged-in RT user to read or modify arbitrary data in the underlying database. The flaw was disclosed alongside the rt-5.0.10/6.0.3 release on 2026-05-20 and carries CVSS 8.8 due to high impact across confidentiality, integrity, and availability. No public exploit identified at time of analysis, and the vulnerability is not listed in CISA KEV.
Technical ContextAI
Request Tracker is a widely deployed Perl-based enterprise ticketing platform from Best Practical (CPE cpe:2.3:a:bestpractical:rt). The defect is a classic CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) where the entry_aggregator query parameter - used by RT's JSON-based ticket search to control how multiple search clauses are AND/OR-joined - is concatenated into a dynamically constructed SQL statement without sufficient validation or parameterization. Because RT stores tickets, user records, transactions, and ACL data in the same RDBMS (MySQL/PostgreSQL/Oracle/MariaDB are all supported), a successful injection reaches the entire RT data model.
RemediationAI
Vendor-released patch: upgrade to RT 5.0.10 (for the 5.0.x branch) or RT 6.0.3 (for the 6.0.x branch), both published 2026-05-20 and available from https://download.bestpractical.com/pub/rt/release/ and the GitHub release pages. If immediate upgrade is not possible, the vendor's documented workaround is to restrict RT account access to trusted users only - practically meaning disabling self-registration, auditing the existing user table, and tightening group memberships - which preserves functionality for internal staff but breaks customer-facing or anonymous-submission workflows. Additional defense-in-depth options include placing RT behind a reverse-proxy WAF rule that rejects unexpected entry_aggregator values on the JSON search endpoint and enabling database query logging to detect anomalous statements, accepting the trade-off of additional log volume and potential false-positive blocks on legitimate complex searches.
