An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-46354 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/coder/coder/v2 (Go): affected all versions; fixed in 2.24.5, 2.29.13, 2.30.8, 2.31.12, 2.32.2, 2.33.3\n- github.com/coder/coder/v2 (Go): affected all versions; fixed in 2.24.5\n- github.com/coder/coder/v2 (Go): affected all versions; fixed in 2.24.5\n- github.com/coder/coder/v2 (Go): affected from 2.29.0; fixed in 2.29.13\n- github.com/coder/coder/v2 (Go): affected from 2.29.0; fixed in 2.29.13\n- github.com/coder/coder/v2 (Go): affected from 2.30.0; fixed in 2.30.8\n- github.com/coder/coder/v2 (Go): affected from 2.30.0; fixed in 2.30.8\n- github.com/coder/coder/v2 (Go): affected from 2.31.0; fixed in 2.31.12\n- github.com/coder/coder/v2 (Go): affected from 2.31.0; fixed in 2.31.12\n- github.com/coder/coder/v2 (Go): affected from 2.32.0-rc.0; fixed in 2.32.2\n- github.com/coder/coder/v2 (Go): affected from 2.32.0-rc.0; fixed in 2.32.2\n- github.com/coder/coder/v2 (Go): affected from 2.33.0-rc.0; fixed in 2.33.3\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-46354/ (Markdown: https://insights.sbomify.com/CVE-2026-46354/index.md)","id":"CVE-2026-46354","markdown":"https://insights.sbomify.com/CVE-2026-46354/index.md","name":"CVE-2026-46354","record":{"aliases":["GHSA-6x44-w3xg-hqqf","GO-2026-5196"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Coder remote dev environment","requires_auth":"none","summary":"Attackers can steal agent session tokens by forging PKCS#7 signatures in Azure instance identity validation, bypassing authentication to access victim workspaces.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"coder","vendor":"coder"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"Coder allows organizations to provision remote development environments via Terraform. In versions prior tp 2.24.5, 2.29.13, 2.30.8, 2.31.12, 2.32.2, and 2.33.3, `azureidentity.Validate()` verifies that the PKCS#7 signer certificate chains to a trusted Azure CA but never verifies the PKCS#7 signature itself. An attacker can embed a legitimate Azure certificate alongside arbitrary content e.g. `{\"vmId\":\"\u003ctarget\u003e\"}` and the forged `vmId` will be accepted returning the victim workspace agent's session token. No authentication is required. The attacker only needs to know a target VM's `vmId` which is a `UUIDv4`. That's a practical limitation which would typically require prior access to be exploited. Versions 2.24.5, 2.29.13, 2.30.8, 2.31.12, 2.32.2, and 2.33.3 patch the issue. As a workaround, reconfigure any Azure templates to use token authentication rather than `azure-instance-identity`.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Coder:
