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-2019-16753 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-2019-16753/ (Markdown: https://insights.sbomify.com/CVE-2019-16753/index.md)","id":"CVE-2019-16753","markdown":"https://insights.sbomify.com/CVE-2019-16753/index.md","name":"CVE-2019-16753","record":{"aliases":["GHSA-3r42-8xcq-6f4v"],"analysis":{"component_type":"other","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cryptocurrency payment system","requires_auth":"none","summary":"Weak signature scheme allows signature reuse across different message types, potentially enabling transaction forgery in DAPS and PIVX.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"decentralized_anonymous_payment_system","vendor":"decentralized_anonymous_payment_system_project"},{"product":"private_instant_verified_transactions","vendor":"pivx"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"An issue was discovered in Decentralized Anonymous Payment System (DAPS) through 2019-08-26.
