An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-21933 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- java (Bitnami): affected all versions; fixed in 1.8.0, 8.0.481, 11.0.30, 17.0.18, 21.0.10, 25.0.2\n- java-min (Bitnami): affected all versions; fixed in 1.8.0, 8.0.481, 11.0.30, 17.0.18, 21.0.10, 25.0.2\n- jre (Bitnami): affected all versions; fixed in 1.8.0, 8.0.481, 11.0.30, 17.0.18, 21.0.10, 25.0.2\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-2026-21933/ (Markdown: https://insights.sbomify.com/CVE-2026-21933/index.md)","id":"CVE-2026-21933","markdown":"https://insights.sbomify.com/CVE-2026-21933/index.md","name":"CVE-2026-21933","record":{"aliases":["BELL-CVE-2026-21933","BIT-java-2026-21933","BIT-java-min-2026-21933","BIT-jre-2026-21933","DEBIAN-CVE-2026-21933","GHSA-5rm3-299f-6m9v","MINI-3cpj-p37m-9hx2","MINI-4f8j-m6r8-9f8h","MINI-4mqg-f7pg-8vhw","MINI-53w9-fc67-4qqc","MINI-57c8-4r86-xcgr","MINI-5h8c-23mq-wh7q","MINI-629f-fmw4-vr7r","MINI-6xx3-cjcp-8mx7","MINI-9362-c583-vqw6","MINI-c3mv-9h8g-mrrq","MINI-c75q-pv6c-c42f","MINI-fj3f-8qf8-f2vx","MINI-g68q-89vh-94mg","MINI-hpqr-9xrq-pmqf","MINI-q9v4-9m49-592w","MINI-qfrq-9hp2-4v7f","MINI-r428-4g4v-5xc3","MINI-r74g-4hc6-4w2q","MINI-r95r-54m3-r57r","MINI-rj58-f4pg-x7h7","MINI-vj37-ww72-hpp5","MINI-w764-vxh9-2wch","MINI-x2g4-qgg5-ffjc","MINI-xc9p-p2vh-f2gw"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Java SE Networking","requires_auth":"none","summary":"Unauthenticated attackers can read and modify accessible data in Oracle Java SE and GraalVM via network protocols, requiring user interaction.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"oracle","cpe":[{"product":"graalvm","vendor":"oracle"},{"product":"graalvm_for_jdk","vendor":"oracle"},{"product":"jdk","vendor":"oracle"},{"product":"jre","vendor":"oracle"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[],"description":"Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Networking).

Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition.  Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in  unauthorized update, insert or delete access to some of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition accessible data as well as  unauthorized read access to a subset of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security.
