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-2026-1002 exists.\n\nAffected packages and fixed versions:\n- io.vertx:vertx-core (Maven): affected all versions; fixed in 4.5.24\n- io.vertx:vertx-core (Maven): affected all versions; fixed in 4.5.24\n- io.vertx:vertx-core (Maven): affected from 5.0.0.CR1; fixed in 5.0.7\n- io.vertx:vertx-core (Maven): affected from 5.0.0.CR1; fixed in 5.0.7\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-2026-1002/ (Markdown: https://insights.sbomify.com/CVE-2026-1002/index.md)","id":"CVE-2026-1002","markdown":"https://insights.sbomify.com/CVE-2026-1002/index.md","name":"CVE-2026-1002","record":{"aliases":["CLEANSTART-2026-EK29154","CLEANSTART-2026-HZ12823","CLEANSTART-2026-ZX15129","ECHO-381d-f8c0-9386","GHSA-cphf-4846-3xx9","MINI-2738-6745-57jq","MINI-2w92-m7jh-998c","MINI-4gjv-q2rr-7w95","MINI-5c9v-2m9c-4hc8","MINI-5gj7-v6jr-mq53","MINI-7rh4-pcv8-8vph","MINI-9ch8-wr77-gc36","MINI-c27r-hqwm-qcp3","MINI-fq9v-7fpf-cwc7","MINI-fwp4-6ph3-w3qq","MINI-j9q3-98q6-r6pv","MINI-jpqr-mxfw-pmww","MINI-p483-68p4-7ccv","MINI-prj6-q539-rcp8","MINI-q4hf-hwpr-6ph7","MINI-r3p4-6j3q-65jq","MINI-w4fx-88x7-m9vq","MINI-wx3v-h66x-cjgh","MINI-xhr7-m4vg-3c4h"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java web framework","requires_auth":"none","summary":"Attackers can deny access to static files in Eclipse Vert.x Web by crafting specific URIs that exploit improper URI normalization in the static handler cache.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[{"product":"vert.x-web","vendor":"eclipse"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:L","version":"4.0"},"cwes":[{"id":"CWE-444","name":"Inconsistent Interpretation of HTTP Requests"}],"description":"The Vert.x Web static handler component cache can be manipulated to deny the access to static files served by the handler using specifically crafted request URI.\n\nThe issue comes from an improper implementation of the C. rule of section 5.2.4 of RFC3986 and is fixed in Vert.x Core component (used by Vert.x Web):  https://github.com/eclipse-vertx/vert.x/pull/5895 \n\nSteps to reproduce\nGiven a file served by the static handler, craft an URI that introduces a string like bar%2F..%2F after the last / char to deny the access to the URI with an HTTP 404 response.
