An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-44454 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 2.29.7, 2.30.2\n- github.com/coder/coder/v2 (Go): affected all versions; fixed in 2.29.7\n- github.com/coder/coder/v2 (Go): affected all versions; fixed in 2.29.7\n- github.com/coder/coder/v2 (Go): affected from 2.30.0; fixed in 2.30.2\n- github.com/coder/coder/v2 (Go): affected from 2.30.0; fixed in 2.30.2\n- github.com/coder/coder (Go): affected all versions; no fix listed\n- github.com/coder/coder (Go): affected all versions up to 0.27.3; no fix listed\n- github.com/coder/coder (Go): affected all versions up to 0.27.3; no fix listed\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-2026-44454/ (Markdown: https://insights.sbomify.com/CVE-2026-44454/index.md)","id":"CVE-2026-44454","markdown":"https://insights.sbomify.com/CVE-2026-44454/index.md","name":"CVE-2026-44454","record":{"aliases":["GHSA-m3cr-vc2j-pm27","GO-2026-5897"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Coder remote dev environment","requires_auth":"none","summary":"Attackers can execute arbitrary commands in provisioned workspaces via crafted dotfiles URIs, potentially leading to code execution.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"coder","vendor":"coder"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Coder allows organizations to provision remote development environments via Terraform. Prior to versions 2.29.7 and 2.30.2, the `dotfiles` registry module passed unsanitized user input to shell commands, allowing arbitrary code execution inside a provisioned workspace. Any user who supplied a crafted `dotfiles_uri` value (for example, one containing shell command substitution such as `$(...)`) could achieve command execution in their own workspace. The Create Workspace page's `mode=auto` deep links amplified this into a one-click attack: an attacker could craft a URL that prefilled `param.dotfiles_uri` and silently provisioned a workspace with the attacker-controlled value, with no explicit user confirmation. In versions 2.29.7 and 2.30.2, input validation was added to the dotfiles module to reject URIs and usernames containing special characters, and the unsafe `eval`/`sh -c` usage was removed. This eliminated the command injection at its source.","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 vulnerable to workspace auto-creation via crafted URL parameters without user consent","id":"CVE-2026-44454","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":8,"n_references":7,"next":{"headline":"Hono: Unvalidated JSX Tag Names in hono/jsx May Allow HTML Injection","id":"CVE-2026-44455"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/coder/coder","purl":"pkg:golang/github.com/coder/coder","source":"GO-2026-5897"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["0.27.3"],"package":"github.com/coder/coder","purl":null,"source":"GHSA-m3cr-vc2j-pm27"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["0.27.3"],"package":"github.com/coder/coder","purl":"pkg:golang/github.com/coder/coder","source":"GHSA-m3cr-vc2j-pm27"},{"ecosystem":"Go","fixed":["2.29.7","2.30.2"],"introduced":["0","2.30.0"],"last_affected":[],"package":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","source":"GO-2026-5897"},{"ecosystem":"Go","fixed":["2.29.7"],"introduced":["0"],"last_affected":[],"package":"github.com/coder/coder/v2","purl":null,"source":"GHSA-m3cr-vc2j-pm27"},{"ecosystem":"Go","fixed":["2.29.7"],"introduced":["0"],"last_affected":[],"package":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","source":"GHSA-m3cr-vc2j-pm27"},{"ecosystem":"Go","fixed":["2.30.2"],"introduced":["2.30.0"],"last_affected":[],"package":"github.com/coder/coder/v2","purl":null,"source":"GHSA-m3cr-vc2j-pm27"},{"ecosystem":"Go","fixed":["2.30.2"],"introduced":["2.30.0"],"last_affected":[],"package":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","source":"GHSA-m3cr-vc2j-pm27"}],"prev":{"headline":"h2o is vulnerable to musl libc stack overflow","id":"CVE-2026-44453"},"products":["coder"],"published":"2026-07-07","related":[{"cvss_score":9.1,"headline":"Coder: PKCS#7 signature bypass in Azure instance identity allows unauthenticated agent token theft","id":"CVE-2026-46354","kev_date_added":null,"published":"2026-07-07"},{"cvss_score":8.7,"headline":"Coder's workspace app upsert allows cross-workspace agent rebinding via user-controlled app ID","id":"CVE-2026-55429","kev_date_added":null,"published":"2026-07-08"},{"cvss_score":8.3,"headline":"Coder vulnerable to SSH config injection via unsanitized server-supplied values in `coder config-ssh`","id":"CVE-2026-55427","kev_date_added":null,"published":"2026-07-07"},{"cvss_score":8.2,"headline":"Coder: Route hijacking through lack of validation of agent-supplied AllowedIPs in tailnet coordinator","id":"CVE-2026-55428","kev_date_added":null,"published":"2026-07-07"},{"cvss_score":8.2,"headline":"Coder's OIDC authentication allows email with partially matching domain to register","id":"CVE-2024-27918","kev_date_added":null,"published":"2024-03-06"},{"cvss_score":8.1,"headline":"Coder's privilege escalation vulnerability could lead to a cross workspace compromise","id":"CVE-2025-58437","kev_date_added":null,"published":"2025-09-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-08","vendors":["coder"]},"summary":"Attackers can execute arbitrary commands in provisioned workspaces via crafted dotfiles URIs, potentially leading to code execution.","url":"https://insights.sbomify.com/CVE-2026-44454/"}
