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-2026-76905 exists.\n\nAffected packages and fixed versions:\n- github.com/getkin/kin-openapi (Go): affected from 0.10.0; fixed in 0.141.0\n- github.com/getkin/kin-openapi (Go): affected from 0.10.0; fixed in 0.141.0\n- github.com/getkin/kin-openapi (Go): affected from 0.10.0; fixed in 0.141.0\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-2026-76905/ (Markdown: https://insights.sbomify.com/CVE-2026-76905/index.md)","id":"CVE-2026-76905","markdown":"https://insights.sbomify.com/CVE-2026-76905/index.md","name":"CVE-2026-76905","record":{"aliases":["DEBIAN-CVE-2026-76905","GHSA-mmfr-pmjx-hw9w","GO-2026-6274","MINI-3344-88gm-6mcc","MINI-3446-q988-7h93","MINI-3c5f-xpmm-9wxq","MINI-47w4-qqf2-vq67","MINI-49wg-x5cp-pf43","MINI-4jvx-6gr5-pf56","MINI-56c3-mw5h-gc8w","MINI-5v7f-m3h6-h78v","MINI-6mvq-4p92-2jwh","MINI-6r9x-fjqh-4pc7","MINI-6rr5-qwfj-8gp7","MINI-728j-j2mp-mwmp","MINI-775h-8xr8-vqvc","MINI-7fxv-fmmr-rf25","MINI-7jqp-wr5x-6r57","MINI-8rm4-fmmx-7m6x","MINI-95rq-f375-jvxf","MINI-9g89-3m59-wh5w","MINI-9rr4-4pff-9gf7","MINI-c6pf-xfpx-pxjf","MINI-f48c-967w-xjp4","MINI-f9r2-crvp-q7f2","MINI-fc8h-4gq5-q35c","MINI-gjh7-h8ww-3hc5","MINI-h5xg-xwjx-hw76","MINI-hpwf-hjvc-3v78","MINI-hw7f-548c-87jx","MINI-j9m2-f72j-jp33","MINI-jgc5-wx3m-p39h","MINI-jrwv-rvm3-fwcw","MINI-mgq2-2w2v-78gg","MINI-p28g-mqh9-c6gp","MINI-prhm-v234-5993","MINI-pvwj-9j3v-p44q","MINI-pxf3-cw3f-rgpj","MINI-q272-7r9h-hp84","MINI-qj6h-2vjx-6c78","MINI-r276-6vqm-xjwj","MINI-rjwx-fr3p-hm5w","MINI-v9rm-376v-2v9p","MINI-w8qr-49mp-4jvh","MINI-wc8r-45wp-5qjp","MINI-x26p-xx9g-7774","UBUNTU-CVE-2026-76905"],"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":"Unauthenticated attackers can cause a denial of service via a nil-pointer panic in kin-openapi when processing malformed multipart/form-data requests.","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 0.10.0 until 0.141.0, openapi3filter.convertParseError in openapi3filter/validation_error_encoder.go dereferences e.Parameter.In without checking whether e.Parameter is nil. A malformed non-string scalar field in a multipart/form-data request body produces a nested ParseError with a nil RequestError.Parameter, and applications that render the validation error through openapi3filter.ConvertErrors or ValidationErrorEncoder panic. An unauthenticated client can repeatedly send such requests to deny service when the application lacks a recovery boundary.
