An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-100353 exists.\n\nAffected packages and fixed versions:\n- github.com/getkin/kin-openapi (Go): affected from 0.136.0; fixed in 0.149.0\n- github.com/getkin/kin-openapi (Go): affected from 0.136.0; fixed in 0.149.0\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-2026-100353/ (Markdown: https://insights.sbomify.com/CVE-2026-100353/index.md)","id":"CVE-2026-100353","markdown":"https://insights.sbomify.com/CVE-2026-100353/index.md","name":"CVE-2026-100353","record":{"aliases":["CLEANSTART-2026-KH25643","ECHO-3b34-ae40-bbcf","GHSA-vrcc-3ch7-hppw","MINI-2wqf-8h3q-m5cx","MINI-5mjx-m6cp-g8v4","MINI-73h7-74q6-pxwv","MINI-f47j-8674-4qv7","MINI-f9h2-qv92-f5jq","MINI-h43h-g8p9-pq2w","MINI-hcfw-pwqg-2722","MINI-hhx3-3732-3fcx","MINI-p72g-chf3-x83v","MINI-qccf-779v-v42f","MINI-qwr9-v4fq-m245","MINI-rg8m-7wf7-wwr2","MINI-xc9f-5cfv-4h55","MINI-xqr6-f699-4hr7","UBUNTU-CVE-2026-100353"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Go OpenAPI library","requires_auth":"none","summary":"An unauthenticated remote attacker can cause a denial of service via a nil-pointer panic in kin-openapi by sending crafted array parameters or bodies.","user_interaction":"not_required","vuln_class":"null_dereference"},"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-476","name":"NULL Pointer Dereference"}],"description":"kin-openapi is a Go project for handling OpenAPI files. From 0.136.0 until 0.149.0, three openapi3filter decoder paths that were missed by the fix for GHSA-p6wj-qrr4-pgh5 lack a nil-items guard for legal OpenAPI 3.1 array schemas. An unauthenticated remote client can trigger a deterministic nil-pointer panic through an array query parameter, a deepObject query parameter containing an array property, or an application/x-www-form-urlencoded request body whose array property appears inside an allOf, anyOf, or oneOf subschema. The query and composed-body paths reach urlValuesDecoder.parseArray, while the deepObject path reaches buildResObj, and all pass a nil items schema into code that dereferences it.
