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-2026-16536 in the wild and no public exploit code.\n\nAffected product: Unknown Simple Google Calendar Outlook Events Widget. 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-2026-16536/ (Markdown: https://insights.sbomify.com/CVE-2026-16536/index.md)","id":"CVE-2026-16536","markdown":"https://insights.sbomify.com/CVE-2026-16536/index.md","name":"CVE-2026-16536","record":{"aliases":["GHSA-ff6j-mvmc-7fp8"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can exploit a lack of URL validation in the Simple Google Calendar Outlook Events Widget to perform Server-Side Request Forgery and potentially read internal responses.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"The Simple Google Calendar Outlook Events Widget WordPress plugin before 3.1.0 does not validate a user-supplied URL before performing a server-side request, allowing unauthenticated attackers to perform Server-Side Request Forgery attacks and, in some cases, read the response of the internal request.","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":"Simple Google Calendar Outlook Events Widget \u003c 3.1.0 - Unauthenticated SSRF via calendar_id","id":"CVE-2026-16536","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"ssrf","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Slick Slider \u003c 0.5.3 - Contributor+ Stored XSS via Gallery Shortcode","id":"CVE-2026-16537"},"packages":[],"prev":{"headline":"Link Library \u003c 7.9.4 - Reflected XSS via Thumbs-Rating likelabel","id":"CVE-2026-16535"},"products":["Simple Google Calendar Outlook Events Widget"],"published":"2026-08-04","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":"2026-08-04","vendors":["Unknown"]},"summary":"Unauthenticated attackers can exploit a lack of URL validation in the Simple Google Calendar Outlook Events Widget to perform Server-Side Request Forgery and potentially read internal responses.","url":"https://insights.sbomify.com/CVE-2026-16536/"}
