An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-107828 in the wild and no public exploit code.\n\nAffected product: banq jivejdon. 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-2026-107828/ (Markdown: https://insights.sbomify.com/CVE-2026-107828/index.md)","id":"CVE-2026-107828","markdown":"https://insights.sbomify.com/CVE-2026-107828/index.md","name":"CVE-2026-107828","record":{"aliases":["GHSA-x2f9-rf6f-hf58"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Jivejdon forum software","requires_auth":"none","summary":"Attackers can bypass authentication and take over accounts by deriving predictable passwords from public Weibo IDs in Jivejdon.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1391","name":"Use of Weak Credentials"}],"description":"Jivejdon through 5.0 contains an authentication bypass vulnerability that allows unauthenticated attackers to access Weibo-created accounts by deriving predictable credentials from public Weibo user IDs.
