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-2025-8838 exists.\n\nAffected product: WinterChenS my-site. 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-2025-8838/ (Markdown: https://insights.sbomify.com/CVE-2025-8838/index.md)","id":"CVE-2025-8838","markdown":"https://insights.sbomify.com/CVE-2025-8838/index.md","name":"CVE-2025-8838","record":{"aliases":["GHSA-5rgc-2f8v-p8gj"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"my-site backend","requires_auth":"none","summary":"Improper authentication in the backend admin interface allows remote attackers to bypass login restrictions, though the maintainer disputes the exploit's validity.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"my-site","vendor":"winterchens"}],"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:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"A vulnerability has been found in WinterChenS my-site up to 1f7525f15934d9d6a278de967f6ec9f1757738d8.
