Prior to 7.1.2, attacker-controlled HTML in inbound emails or tickets could bypass the image URL sanitizer using path traversal sequences. When an authenticated agent views the content, the browser resolves the URL to a protected API endpoint and sends the request with the agent's session cookie, enabling side effects such as forced logout without any user interaction. This issue is fixed in version 7.1.2.","evidence":"cve:CVE-2026-63006","products":[{"name":{"value":"zammad","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"medium","structured":{"id":"CVE-2026-63006","aliases":["CVE-2026-63006"],"metrics":[{"cvssV4_0":{"version":"4.0","baseScore":5.3,"attackVector":"NETWORK","baseSeverity":"MEDIUM","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","userInteraction":"PASSIVE","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"NONE","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":"2026-09-29T18:03:56.994Z","provider":"cve","references":["https://github.com/zammad/zammad/security/advisories/GHSA-33p2-cm7w-62g3","https://github.com/zammad/zammad/commit/856af85c12413087d6a74ffee25b16048a5ed8c3"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-63006","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-29T18:03:28.018447Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-29T18:03:56.994Z"}}],"cna":{"orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M","dateUpdated":"2026-09-25T18:23:13.578Z"}}},"related_cves":[{"value":"CVE-2026-63006","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":3899,"next_before":3899}
