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-2026-83555 in the wild and no public exploit code.\n\nAffected product: Unknown Email Subscribers \u0026 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-2026-83555/ (Markdown: https://insights.sbomify.com/CVE-2026-83555/index.md)","id":"CVE-2026-83555","markdown":"https://insights.sbomify.com/CVE-2026-83555/index.md","name":"CVE-2026-83555","record":{"aliases":["GHSA-52g9-h9fh-xgf2"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can force-unsubscribe or confirm arbitrary subscribers by bypassing token verification in the Email Subscribers plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"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:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"The Email Subscribers \u0026 Newsletters  WordPress plugin before 5.9.35 does not verify the per-subscriber management token before changing a subscriber's subscription status, allowing unauthenticated users to force-unsubscribe or force-confirm an arbitrary subscriber whose email address they know.","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":"Missing authorization in Email Subscribers \u0026 Newsletters","id":"CVE-2026-83555","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"jackson-databind omits java.lang.Comparable from DefaultBaseTypeLimitingValidator's unsafe base types","id":"CVE-2026-83557"},"packages":[],"prev":{"headline":"Cleartext storage of HMAC signing key in Amazon SageMaker Python SDK @step/@remote pipeline path","id":"CVE-2026-83551"},"products":["Email Subscribers \u0026 Newsletters"],"published":"2026-09-23","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":"2026-09-23","vendors":["Unknown"]},"summary":"Unauthenticated attackers can force-unsubscribe or confirm arbitrary subscribers by bypassing token verification in the Email Subscribers plugin.","url":"https://insights.sbomify.com/CVE-2026-83555/"}
