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-2026-55094 in the wild and no public exploit code.\n\nAffected product: taskcluster. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-55094/ (Markdown: https://insights.sbomify.com/CVE-2026-55094/index.md)","id":"CVE-2026-55094","markdown":"https://insights.sbomify.com/CVE-2026-55094/index.md","name":"CVE-2026-55094","record":{"aliases":["GHSA-ccv5-c45x-2q38","GHSA-v484-996h-6h4h"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Taskcluster CI framework","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary code on Taskcluster deployments if an anonymous role exposes the GraphQL endpoint.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-95","name":"Improper Neutralization of Directives in Dynamically Evaluated Code"},{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"},{"id":"CWE-250","name":"Execution with Unnecessary Privileges"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Taskcluster is the task execution framework that supports Mozilla's continuous integration and release processes.
