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-2026-83533 in the wild and no public exploit code.\n\nAffected product: Unknown WP Express Checkout. 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-2026-83533/ (Markdown: https://insights.sbomify.com/CVE-2026-83533/index.md)","id":"CVE-2026-83533","markdown":"https://insights.sbomify.com/CVE-2026-83533/index.md","name":"CVE-2026-83533","record":{"aliases":["GHSA-rr9j-x6q5-q5pf"],"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 bypass payment verification in WP Express Checkout to mark orders as paid without actually paying.","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":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"The WP Express Checkout WordPress plugin before 2.4.9 does not verify server-side that a payment was actually completed before marking an order as paid, allowing unauthenticated users to forge a completed order without paying.","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":"WP Express Checkout \u003c 2.4.9 - Unauthenticated Payment Bypass via wpec_process_payment","id":"CVE-2026-83533","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":"PostgreSQL Anonymizer: Privilege escalation to superuser via anon.anonymize_database_parallel()","id":"CVE-2026-83534"},"packages":[],"prev":{"headline":"Custom Menu Wizard \u003c= 3.3.1 - Contributor+ Stored XSS via Shortcode Attributes","id":"CVE-2026-83532"},"products":["WP Express Checkout"],"published":"2026-09-02","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-02","vendors":["Unknown"]},"summary":"Unauthenticated attackers can bypass payment verification in WP Express Checkout to mark orders as paid without actually paying.","url":"https://insights.sbomify.com/CVE-2026-83533/"}
