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-2026-101914 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @grpc/grpc-js-xds (npm): affected all versions; fixed in 1.13.1\n- @grpc/grpc-js-xds (npm): affected all versions; fixed in 1.13.1\n- @grpc/grpc-js-xds (npm): affected from 1.14.0; fixed in 1.14.1\n- @grpc/grpc-js-xds (npm): affected from 1.14.0; fixed in 1.14.1\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-2026-101914/ (Markdown: https://insights.sbomify.com/CVE-2026-101914/index.md)","id":"CVE-2026-101914","markdown":"https://insights.sbomify.com/CVE-2026-101914/index.md","name":"CVE-2026-101914","record":{"aliases":["GHSA-88h9-xgvx-hvf2"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"gRPC JavaScript library","requires_auth":"none","summary":"Attackers can bypass RBAC restrictions in @grpc/grpc-js by exploiting a prefix matching flaw in case-insensitive path matching, gaining unauthorized access to protected methods.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-187","name":"Partial String Comparison"}],"description":"@grpc/grpc-js implements the core functionality of gRPC purely in JavaScript, without a C++ addon. Prior to 1.13.1 and 1.14.1, the exact path (method name) matcher used by RBAC performs a prefix comparison instead of an equality comparison when case-insensitive matching is enabled. If one service method name prefixes another and the methods have different access rules, a request for the longer method can match the shorter method's rule and cause incorrect authorization.
