An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-16268 exists.\n\nAffected product: Unknown Newsletters. 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-2026-16268/ (Markdown: https://insights.sbomify.com/CVE-2026-16268/index.md)","id":"CVE-2026-16268","markdown":"https://insights.sbomify.com/CVE-2026-16268/index.md","name":"CVE-2026-16268","record":{"aliases":["GHSA-mhrm-79mh-vhfj"],"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 force the Newsletters WordPress plugin to fetch arbitrary URLs, enabling internal network access and potential data exposure.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"The Newsletters WordPress plugin before 4.16 does not authenticate or validate a bounce-processing request before fetching a user-supplied URL on the server side, allowing unauthenticated attackers to make the site issue requests to arbitrary internal or external hosts.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2026/CVE-2026-16268.yaml","stars":null,"title":"Newsletters \u003c 4.16 - Unauthenticated SSRF via SNS Bounce Handler"}],"tier":"weaponised"},"has_fix":null,"headline":"Newsletters \u003c 4.16 - Unauthenticated Server-Side Request Forgery via SNS Bounce Handler","id":"CVE-2026-16268","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"ssrf","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Newsletters \u003c 4.16 - Unauthenticated API Authentication Bypass via Type Juggling","id":"CVE-2026-16269"},"packages":[],"prev":{"headline":"Newsletters \u003c 4.16 - Unauthenticated PHP Object Injection via Date Form Field","id":"CVE-2026-16267"},"products":["Newsletters"],"published":"2026-08-06","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)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-06","vendors":["Unknown"]},"summary":"Unauthenticated attackers can force the Newsletters WordPress plugin to fetch arbitrary URLs, enabling internal network access and potential data exposure.","url":"https://insights.sbomify.com/CVE-2026-16268/"}
