Prior to 7.1.2, the legacy destroy_form action on AttachmentsController deletes UploadCache Store records based solely on a user-supplied form_id without verifying that the requesting user owns those records. An authenticated attacker who learns another user's pending-upload UUID can silently remove temporary file uploads before the victim submits their ticket or article. This issue is fixed in version 7.1.2.","evidence":"cve:CVE-2026-65828","products":[{"name":{"value":"zammad","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"low","structured":{"id":"CVE-2026-65828","aliases":["CVE-2026-65828"],"metrics":[{"cvssV4_0":{"version":"4.0","baseScore":2.3,"attackVector":"NETWORK","baseSeverity":"LOW","vectorString":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","userInteraction":"NONE","attackComplexity":"HIGH","attackRequirements":"NONE","privilegesRequired":"LOW","subIntegrityImpact":"NONE","vulnIntegrityImpact":"LOW","subAvailabilityImpact":"NONE","vulnAvailabilityImpact":"LOW","subConfidentialityImpact":"NONE","vulnConfidentialityImpact":"NONE"}}],"affected":[{"vendor":"zammad","product":"zammad","versions":[{"status":"affected","version":"< 7.1.2"}]}],"modified":"2026-09-25T18:38:58.822Z","provider":"cve","references":["https://github.com/zammad/zammad/security/advisories/GHSA-x4f3-367g-m93g","https://github.com/zammad/zammad/commit/3b755736fdbee8ff6ddf53661d6912d3d3028325"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-65828","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-25T18:38:49.403514Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-25T18:38:58.822Z"}}],"cna":{"orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M","dateUpdated":"2026-09-25T17:28:13.159Z"}}},"related_cves":[{"value":"CVE-2026-65828","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":2238,"next_before":2238}
