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-2026-89411 in the wild and no public exploit code.\n\nAffected product: Unknown Paymattic. 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-2026-89411/ (Markdown: https://insights.sbomify.com/CVE-2026-89411/index.md)","id":"CVE-2026-89411","markdown":"https://insights.sbomify.com/CVE-2026-89411/index.md","name":"CVE-2026-89411","record":{"aliases":["GHSA-xhxc-69hm-mqvf"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress payment plugin","requires_auth":"none","summary":"Unauthenticated attackers can mark arbitrary pending orders as paid by confirming a smaller Stripe payment, bypassing payment verification in Paymattic.","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 Paymattic WordPress plugin from 4.6.20 before 4.6.26 does not verify that a confirmed Stripe payment belongs to the order it is applied to, allowing unauthenticated users to mark an arbitrary pending order as paid by confirming a smaller payment of their own against it.","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":"Paymattic \u003c 4.6.26 - Unauthenticated Payment Bypass via Unbound Stripe PaymentIntent","id":"CVE-2026-89411","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":"TranslatePress \u003c= 3.3.5 - Unauthenticated Stored Cross-Site Scripting via Translation Memory Suggestion Panel","id":"CVE-2026-89412"},"packages":[],"prev":{"headline":"Out-of-bounds read in Z-Wave NCP SPI Handler","id":"CVE-2026-89410"},"products":["Paymattic"],"published":"2026-09-28","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":"2026-09-28","vendors":["Unknown"]},"summary":"Unauthenticated attackers can mark arbitrary pending orders as paid by confirming a smaller Stripe payment, bypassing payment verification in Paymattic.","url":"https://insights.sbomify.com/CVE-2026-89411/"}
