Prior to 7.1.2, any authenticated user can call the REST endpoint for getting a tag list and receive the tag names for the given ticket, regardless of whether they have access to that ticket. Tags are an internal categorization feature and may contain sensitive labels. Ticket IDs are sequential integers, making bulk enumeration straightforward. This issue is fixed in version 7.1.2.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":5.3},"cvss_v3":null,"cwes":["CWE-639"],"references":["https://github.com/zammad/zammad/commit/13217eb6b3fdf350228b13f8cf69f640b8fd0da2","https://github.com/zammad/zammad/commit/d1a5eabdd1285b202f75761c4406edc5509e217e","https://github.com/zammad/zammad/security/advisories/GHSA-6vgm-xxp4-p6jv"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:48.555445741+00:00"},"epss":{"cve":"CVE-2026-84460","score":0.00259,"percentile":0.1739,"date":"2026-10-25"},"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).
