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-2025-63807 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2025-63807/ (Markdown: https://insights.sbomify.com/CVE-2025-63807/index.md)","id":"CVE-2025-63807","markdown":"https://insights.sbomify.com/CVE-2025-63807/index.md","name":"CVE-2025-63807","record":{"aliases":["GHSA-xqf6-9hf7-323f"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"University BBS","requires_auth":"none","summary":"Attackers can brute-force weak verification codes due to missing rate limiting, leading to account takeover via password reset.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"blogin","vendor":"2dogz"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"},{"id":"CWE-1390","name":"Weak Authentication"}],"description":"An issue was discovered in weijiang1994 university-bbs (aka Blogin) in commit 9e06bab430bfc729f27b4284ba7570db3b11ce84 (2025-01-13).
