Prior to versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2, the devcontainer recreate endpoint relied on route middleware that checked only `ActionRead` on the workspace and, unlike the sibling delete endpoint, performed no `ActionUpdate` check before triggering the destructive rebuild. Exploitation requires an existing low-privilege role with access to the target workspace. The fix in versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2 adds an explicit `ActionUpdate` authorization check before the agent is dialed like the delete endpoint. No known workarounds are available."}], "lastModified": "2026-07-08T19:39:45.713", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:coder:coder:*:*:*:*:*:go:*:*", "vulnerable": true, "matchCriteriaId": "F97FAF48-192E-4814-82A5-085C44F1D261", "versionEndExcluding": "2.29.17"}, {"criteria": "cpe:2.3:a:coder:coder:*:*:*:*:*:go:*:*", "vulnerable": true, "matchCriteriaId": "7ABD4A9B-6AE8-47D8-A1B7-91E42EE0481B", "versionEndExcluding": "2.32.7", "versionStartIncluding": "2.30.0"}, {"criteria": "cpe:2.3:a:coder:coder:*:*:*:*:*:go:*:*", "vulnerable": true, "matchCriteriaId": "F759EEF3-6EAE-475B-85F8-38E7D7B47438", "versionEndExcluding": "2.33.8", "versionStartIncluding": "2.33.0"}, {"criteria": "cpe:2.3:a:coder:coder:*:*:*:*:*:go:*:*", "vulnerable": true, "matchCriteriaId": "397A02BF-6CF6-40B1-B792-D7CB9D229050", "versionEndExcluding": "2.34.2", "versionStartIncluding": "2.34.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
