Privilege escalation and information disclosure in Best Practical's Request Tracker (RT) 6.0.0-6.0.2 and versions before 5.0.10 lets a privileged but non-administrative user harvest other users' authentication credentials - including those of administrators - through the REST 2.0 API and replay them against RT's RSS/iCal feed endpoints to read data as those victims. Because the same credential-exposing request also rotates the tokens, exploitation is destructive: it silently invalidates every previously distributed feed URL across the instance. No public exploit has been identified at time of analysis; the flaw is fixed in RT 5.0.10 and 6.0.3.
Authentication bypass in Best Practical's Request Tracker (RT) versions 5.0.9 and prior, and 6.0.0 through 6.0.2, allows remote attackers to log in as any LDAP-backed user without valid credentials when RT is configured with LDAP or Active Directory authentication and the LDAP server accepts unauthenticated bind requests. The flaw, fixed in RT 5.0.10 and 6.0.3 released 2026-05-20, carries a CVSS 8.1 and has no public exploit identified at time of analysis, but the trivial nature of the bypass against vulnerable LDAP policies makes it high-priority for any RT deployment using directory-based auth.
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.
Cross-site request forgery in Best Practical Request Tracker (RT) versions 6.0.0 through 6.0.2 allows remote attackers to perform arbitrary state-changing actions on behalf of an authenticated RT user who is lured to a malicious web page. The flaw carries a CVSS 7.1 (high integrity impact) and has been addressed in RT 6.0.3 released 2026-05-20, but no public exploit identified at time of analysis and the CVE is not present in CISA KEV.
Reflected Cross-Site Scripting in Best Practical RT versions 5.0.4-5.0.9 and 6.0.0-6.0.2 allows an unauthenticated attacker to execute arbitrary JavaScript in the browser session of an authenticated RT user by inducing that user to visit a specially crafted URL. The CVSS vector's Changed scope (S:C) indicates the injected script can impact browser security context beyond the vulnerable RT component itself, including potential session hijacking or in-browser data exfiltration. Vendor-released patches are confirmed in versions 5.0.10 and 6.0.3 (released 2026-05-20); no active exploitation has been identified at time of analysis.
Stored XSS in Best Practical RT (versions 5.0.0-5.0.9 and 6.0.0-6.0.2) allows any authenticated user with file upload permissions to embed malicious JavaScript in an uploaded file that executes in the browser session of any RT user who later views or downloads that content. The root cause is RT serving uploaded files inline rather than forcing browser download via Content-Disposition: attachment, enabling browsers to render and execute embedded scripts. Vendor-released patches 5.0.10 and 6.0.3 are available (released 2026-05-20); no public exploit identified at time of analysis.
Stored Cross-Site Scripting in Best Practical RT versions 6.0.0 through 6.0.2 allows an authenticated attacker with write access to inject persistent JavaScript payloads into ticket or configuration data, which then executes in the browsers of other RT users who view the affected pages. The CVSS scope change (S:C) reflects cross-user browser context impact - injected scripts operate in the victim's session, enabling session hijacking or unauthorized actions. No public exploit is identified at time of analysis; vendor-released patch is confirmed in RT 6.0.3, published 2026-05-20.
Reflected Cross-Site Scripting in RT (Request Tracker) 6.0.0 through 6.0.2 allows an unauthenticated network attacker to execute arbitrary JavaScript in an authenticated user's browser session by inducing that user to visit a crafted URL. The CVSS:3.1 scope-change flag (S:C) confirms the payload crosses from the RT application context into the victim's browser, enabling session token theft or unauthorized RT actions on behalf of the victim. No public exploit code or CISA KEV listing has been identified at time of analysis; the vendor-released fix is RT 6.0.3, published 2026-05-20.
Spreadsheet formula injection in Best Practical Request Tracker (RT) allows a low-privileged authenticated attacker to embed malicious formulas in ticket fields that execute when an administrator or staff member exports data to CSV and opens the file in a spreadsheet application. Affected versions span the entire RT 5.0 line prior to 5.0.10 and RT 6.0.0 through 6.0.2. No public exploit code has been identified at time of analysis and no CISA KEV listing exists, but the attack surface is broad given that CSV exports are a routine administrative workflow in ticketing systems.
