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-2026-102276 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- brace-expansion (npm): affected all versions; fixed in 1.1.19\n- brace-expansion (npm): affected all versions; fixed in 1.1.19\n- brace-expansion (npm): affected from 2.0.0; fixed in 2.1.5\n- brace-expansion (npm): affected from 2.0.0; fixed in 2.1.5\n- brace-expansion (npm): affected from 3.0.0; fixed in 3.0.7\n- brace-expansion (npm): affected from 3.0.0; fixed in 3.0.7\n- brace-expansion (npm): affected from 4.0.0; fixed in 5.0.10\n- brace-expansion (npm): affected from 4.0.0; fixed in 5.0.10\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-2026-102276/ (Markdown: https://insights.sbomify.com/CVE-2026-102276/index.md)","id":"CVE-2026-102276","markdown":"https://insights.sbomify.com/CVE-2026-102276/index.md","name":"CVE-2026-102276","record":{"aliases":["AZL-105075","AZL-105096","AZL-105248","CLEANSTART-2026-DU29459","CLEANSTART-2026-DY98563","CLEANSTART-2026-KY36668","CLEANSTART-2026-MC48922","CLEANSTART-2026-NW59301","CLEANSTART-2026-QQ47371","CLSA-2026-1790807349","CLSA-2026-1790807354","CLSA-2026-1790807467","CLSA-2026-1790856945","CLSA-2026-1790863041","CLSA-2026-1790864778","CLSA-2026-1791215851","CLSA-2026-1791215922","CLSA-2026-1791226379","CLSA-2026-1791226863","CLSA-2026-1791278923","DEBIAN-CVE-2026-102276","ECHO-5000-011f-5261","GHSA-6j4f-fj2g-mc7p","MINI-27xx-qgrm-vqc4","MINI-2p92-9qfw-p6wc","MINI-3f77-m92v-2xmr","MINI-3m36-hq59-q5qc","MINI-49fv-g965-4rc4","MINI-4m38-4g64-wc55","MINI-52m4-2x6p-f5fm","MINI-5m6j-7qj5-7rgp","MINI-5mx9-x3vm-qwqx","MINI-5q3m-vf89-3c6p","MINI-6f3m-c8rr-38wq","MINI-7f9w-jqwq-vmqc","MINI-8cr9-j7p4-jfvc","MINI-8j97-9cj4-chjx","MINI-9g7m-jhm9-w2p4","MINI-9q2r-7xpq-fqf7","MINI-c4vq-39fv-9fhh","MINI-cjwf-vj2q-245v","MINI-cv6g-8pgf-j8qf","MINI-cv8v-24vr-7fw9","MINI-fjqr-7wxw-9mh7","MINI-gf4j-56vc-xfg9","MINI-h87f-q8jh-7j85","MINI-j888-v9wp-5cqg","MINI-mgg3-hjm4-fwpf","MINI-p3r6-2h7q-xqr5","MINI-p4w5-jvrm-gpcx","MINI-pcwx-jjmp-xqgw","MINI-pxww-wrfx-jpr7","MINI-q3x2-pgvv-qgw6","MINI-rp5m-m6v6-gv4j","MINI-rph4-33gm-3mr9","MINI-rvc4-7q6f-qrh2","MINI-vcfc-w6hc-g2c7","MINI-w73w-3j88-mv8m","MINI-wpxr-v5hp-mvp3","ROOT-APP-NPM-CVE-2026-102276","UBUNTU-CVE-2026-102276","openSUSE-SU-2026:12062-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript brace expansion library","requires_auth":"none","summary":"Crafted brace patterns cause stack exhaustion in the brace-expansion library, leading to a Node.js process crash and denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-674","name":"Uncontrolled Recursion"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to 1.1.19, 2.1.5, 3.0.7, and 5.0.10, crafted brace patterns can exhaust the native stack in parseCommaParts because parseCommaParts recursively processes the remainder once per brace group and uses push.apply to pass every element of a very large comma-part array as a function argument. Patterns containing many comma-separated brace groups trigger the recursive path, while the large array triggers the argument-array path without deep recursion. These paths cause recursive and argument-array native stack exhaustion before max or maxLength can limit output, potentially terminating the Node.js process in a process-terminating denial of service.
