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-2026-21977 in the wild and no public exploit code.\n\nAffected product: Oracle Zero Data Loss Recovery Appliance Software. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-21977/ (Markdown: https://insights.sbomify.com/CVE-2026-21977/index.md)","id":"CVE-2026-21977","markdown":"https://insights.sbomify.com/CVE-2026-21977/index.md","name":"CVE-2026-21977","record":{"aliases":["GHSA-j6xw-536h-888x"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Oracle ZDLRA Software","requires_auth":"none","summary":"An unauthenticated attacker can gain unauthorized read access to a subset of data in Oracle Zero Data Loss Recovery Appliance Software via network access.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"oracle","cpe":[],"cvss":{"score":3.1,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[],"description":"Vulnerability in the Oracle Zero Data Loss Recovery Appliance Software product of Oracle Zero Data Loss Recovery Appliance (component: Security).
