{"id":"CVE-2022-36066","summary":"Discourse vulnerable to RCE via admins uploading maliciously zipped file","details":"Discourse is an open source discussion platform. In versions prior to 2.8.9 on the `stable` branch and prior to 2.9.0.beta10 on the `beta` and `tests-passed` branches, admins can upload a maliciously crafted Zip or Gzip Tar archive to write files at arbitrary locations and trigger remote code execution. The problem is patched in version 2.8.9 on the `stable` branch and version 2.9.0.beta10 on the `beta` and `tests-passed` branches. There are no known workarounds.","aliases":["BIT-discourse-2022-36066","GHSA-grvh-qcpg-hfmv"],"modified":"2026-09-30T03:45:15.437776072Z","published":"2022-09-29T19:35:09Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/36xxx/CVE-2022-36066.json","unresolved_ranges":[{"extracted_events":[{"fixed":"2.8.9"},{"introduced":"2.9.0.beta0"},{"fixed":"2.9.0.beta10"}],"source":"AFFECTED_FIELD"}],"cna_assigner":"GitHub_M","cwe_ids":["CWE-434"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/36xxx/CVE-2022-36066.json"},{"type":"ADVISORY","url":"https://github.com/discourse/discourse/security/advisories/GHSA-grvh-qcpg-hfmv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-36066"},{"type":"FIX","url":"https://github.com/discourse/discourse/commit/b27d5626d208a22c516a0adfda7554b67b493835"},{"type":"FIX","url":"https://github.com/discourse/discourse/pull/18421"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/discourse/discourse","events":[{"introduced":"0"},{"fixed":"b27d5626d208a22c516a0adfda7554b67b493835"}],"database_specific":{"source":"REFERENCES"}}],"versions":["v2.9.0.beta9","v2.9.0.beta8","v2.9.0.beta7","v2.9.0.beta6","v2.9.0.beta5","v2.9.0.beta4","v2.9.0.beta3","v2.9.0.beta2","v2.9.0.beta1","v2.8.0.beta11","v2.8.0.beta10","v2.8.0.beta9","v2.8.0.beta8","v2.8.0.beta7","v2.8.0.beta6","v2.8.0.beta5","v2.8.0.beta4","v2.8.0.beta3","v2.8.0.beta2","v2.8.0.beta1","v2.7.0.beta9","v2.7.0.beta8","v2.7.0.beta7","v2.7.0.beta6","v2.7.0.beta5","v2.7.0.beta4","v2.7.0.beta3","v2.7.0.beta2","v2.7.0.beta1","v2.6.0.beta6","v2.6.0.beta5","v2.6.0.beta4","v2.6.0.beta3","v2.6.0.beta2","v2.6.0.beta1","v2.5.0.beta7","v2.5.0.beta6","v2.5.0.beta5","v2.5.0.beta4","v2.5.0.beta3","v2.5.0.beta2","v2.5.0.beta1","v2.4.0.beta11","v2.4.0.beta10","v2.4.0.beta9","v2.4.0.beta8","v2.4.0.beta7","v2.4.0.beta6","v2.4.0.beta5","v2.4.0.beta4","v2.4.0.beta3","v2.4.0.beta2","v2.4.0.beta1","v2.3.0.beta11","v2.3.0.beta10","v2.3.0.beta9","v2.3.0.beta8","v2.3.0.beta7","v2.3.0.beta6","v2.3.0.beta5","v2.3.0.beta4","v2.3.0.beta3","v2.3.0.beta2","v2.3.0.beta1","v2.2.0.beta10","v2.2.0.beta9","v2.2.0.beta8","v2.2.0.beta7","v2.2.0.beta6","v2.2.0.beta5","v2.2.0.beta4","v2.2.0.beta3","v2.2.0.beta2","v2.2.0.beta1","v2.1.0.beta6","v2.1.0.beta5","v2.1.0.beta4","v2.1.0.beta3","v2.1.0.beta2","v2.1.0.beta1","v2.0.0.beta10","v2.0.0.beta9","v2.0.0.beta8","v2.0.0.beta7","v2.0.0.beta6","v2.0.0.beta5","v2.0.0.beta4","v2.0.0.beta3","v2.0.0.beta2","v2.0.0.beta1","v1.9.0.beta17","v1.9.0.beta16","v1.9.0.beta15","v1.9.0.beta14","v1.9.0.beta13","v1.9.0.beta12","v1.9.0.beta11","v1.9.0.beta10","v1.9.0.beta9","v1.9.0.beta8","v1.9.0.beta7","v1.9.0.beta6","v1.9.0.beta5","v1.9.0.beta4","v1.9.0.beta3","v1.9.0.beta2","v1.9.0.beta1","v1.8.0.beta13","v1.8.0.beta12","v1.8.0.beta11","v1.8.0.beta10","v1.8.0.beta9","v1.8.0.beta8","v1.8.0.beta7","v1.8.0.beta6","v1.8.0.beta5","v1.8.0.beta4","v1.8.0.beta3","v1.8.0.beta2","v1.8.0.beta1","v1.7.0.beta11","v1.7.0.beta10","v1.7.0.beta9","v1.7.0.beta8","v1.7.0.beta7","v1.7.0.beta6","v1.7.0.beta5","v1.7.0.beta4","v1.7.0.beta3","v1.7.0.beta1","v1.7.0.beta2","v1.6.0.beta12","v1.6.0.beta11","v1.6.0.beta10","v1.6.0.beta9","v1.6.0.beta8","v1.6.0.beta7","v1.6.0.beta6","v1.6.0.beta5","v1.6.0.beta4","v1.6.0.beta3","v1.6.0.beta2","v1.6.0.beta1","v1.5.0.beta14","v1.5.0.beta13b","v1.5.0.beta13","v1.5.0.beta12","v1.5.0.beta11","v1.5.0.beta10","v1.5.0.beta9","v1.5.0.beta8","v1.5.0.beta7","v1.5.0.beta6","v1.5.0.beta5","v1.5.0.beta4","v1.5.0.beta2","v1.5.0.beta1","v1.4.0.beta12","v1.4.0.beta11","v1.4.0.beta10","v1.4.0.beta9","v1.4.0.beta8","v1.4.0.beta7","v1.4.0.beta6","v1.4.0.beta5","v1.4.0.beta4","v1.4.0.beta3","v1.4.0.beta2","v1.4.0.beta1","v1.3.0.beta11","v1.3.0.beta10","v1.3.0.beta9","v1.3.0.beta6","v1.3.0.beta5","v1.3.0.beta4","v1.3.0.beta3","v1.3.0.beta2","v1.3.0.beta1","v1.2.0.beta9","v1.2.0.beta8","v1.2.0.beta7","v1.2.0.beta6","v1.2.0.beta5","v1.2.0.beta4","v1.2.0.beta3","v1.2.0.beta2","v1.2.0.beta1","v1.1.0.beta8","v1.1.0.beta7","v1.1.0.beta6b","v1.1.0.beta6","v1.1.0.beta5","v1.1.0.beta4","v1.1.0.beta3","v1.1.0.beta2","v1.0.0","v0.9.9.18","v0.9.9.17","v0.9.9.16","v0.9.9.15","v0.9.9.14","v0.9.9.13","v0.9.9.12","v0.9.9.11","v0.9.9.10","v0.9.9.9","v0.9.9.8","v0.9.9.7","v0.9.9.6","v0.9.9.5","v0.9.9.4","v0.9.9.3","v0.9.9.2","v0.9.9.1","v0.9.8.11","v0.9.8.10","v0.9.8.9","v0.9.8.8","v0.9.8.7","v0.9.8.6","v0.9.8.5","v0.9.8.4","v0.9.8.3","v0.9.8.2","v0.9.8.1","v0.9.8","v0.9.7.9","v0.9.7.8","v0.9.7.7","v0.9.7.6","v0.9.7.5","v0.9.7.4","v0.9.7.3","v0.9.7.2","v0.9.7.1","v0.9.7","v0.9.6.4","v0.9.6.3","v0.9.6.1","v0.9.6","v0.9.5.2","v0.9.5.1","v0.9.5","v0.9.4","v0.9.3","v0.9.2.6","v0.9.2.5","v0.9.2","v0.9.1","v0.9.0","v0.8.9","v0.8.8","v0.8.7","v0.8.6","v0.8.5","v0.8.4","v0.8.3","v0.8.2","v0.8.1","v0.8.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-36066.json"}}],"schema_version":"1.9.0","severity":[
