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-2026-16990 in the wild and no public exploit code.\n\nAffected product: Unknown Payment Button for PayPal. 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-2026-16990/ (Markdown: https://insights.sbomify.com/CVE-2026-16990/index.md)","id":"CVE-2026-16990","markdown":"https://insights.sbomify.com/CVE-2026-16990/index.md","name":"CVE-2026-16990","record":{"aliases":["GHSA-4h7v-8qrm-x2jj"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can manipulate payment amounts in the PayPal WordPress plugin, allowing them to create orders for arbitrary lower prices.","user_interaction":"not_required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[],"description":"The Payment Button for PayPal WordPress plugin through 1.2.3.44 does not enforce the merchant-configured price server-side and trusts a client-supplied payment amount, allowing unauthenticated attackers to create a real PayPal order against the merchant for an arbitrary lower amount.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Payment Button for PayPal \u003c= 1.2.3.44 - Unauthenticated Payment Price Manipulation","id":"CVE-2026-16990","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"business_logic","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Vulnerabilities in IBM AIX and PowerVM VIOS","id":"CVE-2026-16991"},"packages":[],"prev":{"headline":"Vulnerabilities in IBM AIX and PowerVM VIOS","id":"CVE-2026-16989"},"products":["Payment Button for PayPal"],"published":"2026-08-12","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-12","vendors":["Unknown"]},"summary":"Unauthenticated attackers can manipulate payment amounts in the PayPal WordPress plugin, allowing them to create orders for arbitrary lower prices.","url":"https://insights.sbomify.com/CVE-2026-16990/"}
