An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-39498 in the wild and no public exploit code.\n\nAffected product: Yeeaddons YayMail. 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-2026-39498/ (Markdown: https://insights.sbomify.com/CVE-2026-39498/index.md)","id":"CVE-2026-39498","markdown":"https://insights.sbomify.com/CVE-2026-39498/index.md","name":"CVE-2026-39498","record":{"aliases":["GHSA-h674-wp7j-pj7m"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"high_privilege","summary":"A PHP object injection vulnerability in the YayMail WordPress plugin allows attackers to potentially execute arbitrary code.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Shop manager PHP Object Injection in YayMail \u003c= 4.3.3 versions.","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":"WordPress YayMail plugin \u003c= 4.3.3 - PHP Object Injection vulnerability","id":"CVE-2026-39498","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Deserialization in Advanced Product Fields (Product Addons) for WooCommerce","id":"CVE-2026-39499"},"packages":[],"prev":{"headline":"WordPress FOX plugin \u003c= 1.4.5 - SQL Injection vulnerability","id":"CVE-2026-39497"},"products":["YayMail"],"published":"2026-06-15","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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-06-16","vendors":["Yeeaddons"]},"summary":"A PHP object injection vulnerability in the YayMail WordPress plugin allows attackers to potentially execute arbitrary code.","url":"https://insights.sbomify.com/CVE-2026-39498/"}
