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-2026-16650 in the wild and no public exploit code.\n\nAffected product: Unknown Charitable. 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-2026-16650/ (Markdown: https://insights.sbomify.com/CVE-2026-16650/index.md)","id":"CVE-2026-16650","markdown":"https://insights.sbomify.com/CVE-2026-16650/index.md","name":"CVE-2026-16650","record":{"aliases":["GHSA-r6r4-9w99-4w36"],"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 Square webhook signature verification to forge payment notifications, marking donations as paid without actual funds.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"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 Charitable WordPress plugin before 1.8.12 does not verify the authenticity of incoming Square payment webhook events in a default configuration, allowing unauthenticated attackers to forge webhook notifications that mark donations as paid without any real payment.","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":"Charitable \u003c 1.8.12 - Unauthenticated Donation Payment-Status Manipulation via Square Webhook Signature Bypass","id":"CVE-2026-16650","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"temporalio/sqlparser malformed MySQL version comments can cause a panic","id":"CVE-2026-16651"},"packages":[],"prev":{"headline":"Gravity Forms \u003c= 2.10.5 - Unauthenticated Stored Cross-Site Scripting via Post Body Field Value","id":"CVE-2026-16649"},"products":["Charitable"],"published":"2026-08-21","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":"2026-08-21","vendors":["Unknown"]},"summary":"Unauthenticated attackers can bypass Square webhook signature verification to forge payment notifications, marking donations as paid without actual funds.","url":"https://insights.sbomify.com/CVE-2026-16650/"}
