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-2025-53628 exists.\n\nAffected product: yhirose cpp-httplib. 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-2025-53628/ (Markdown: https://insights.sbomify.com/CVE-2025-53628/index.md)","id":"CVE-2025-53628","markdown":"https://insights.sbomify.com/CVE-2025-53628/index.md","name":"CVE-2025-53628","record":{"aliases":["DEBIAN-CVE-2025-53628","ECHO-afa3-f31f-8c19","UBUNTU-CVE-2025-53628"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"C++ HTTP library","requires_auth":"none","summary":"An attacker can cause arbitrary memory allocation and denial of service in cpp-httplib by sending excessively long lines.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"cpp-httplib","vendor":"yhirose"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-444","name":"Inconsistent Interpretation of HTTP Requests"},{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"},{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"cpp-httplib is a C++11 single-file header-only cross platform HTTP/HTTPS library.
