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-2026-111675 exists.\n\nAffected product: xiaochong0302 course-tencent-cloud. 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-2026-111675/ (Markdown: https://insights.sbomify.com/CVE-2026-111675/index.md)","id":"CVE-2026-111675","markdown":"https://insights.sbomify.com/CVE-2026-111675/index.md","name":"CVE-2026-111675","record":{"aliases":["GHSA-h2mg-h5vq-xqx3"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Course management system","requires_auth":"none","summary":"Unauthenticated attackers can brute force 6-digit verification codes to take over user accounts due to missing rate limits and code invalidation.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"Course-tencent-cloud through 2.0.1 contains an improper restriction of authentication attempts vulnerability that allows unauthenticated attackers to brute force 6-digit SMS/email verification codes, which are never invalidated or attempt-limited.
