The change applies to the whole RT instance\n      once RTIR is installed, not only to RTIR's own queues. Anyone who\n      can add HTML content to a ticket on such an instance can store\n      such a link. That includes an unauthenticated sender of HTML email\n      to the Incident Reports queue, which RTIR opens to everyone by\n      default. Script runs when a user clicks the link, in that user's\n      session, and can act in RT with that user's authority.\n\n\nThis issue was fixed in version 5.0.11 and 6.0.4","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","score":5.3},"cvss_v3":null,"cwes":["CWE-79"],"references":["https://cert.pl/en/posts/2026/10/CVE-2026-105454","https://requesttracker.com/rtir/"],"products":[],"source":"nvd","synced_at":"2026-10-30T16:41:48.501372702+00:00"},"epss":null,"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
