An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-5958 in the wild and no public exploit code.\n\nAffected product: Unknown POST SMTP Mailer. 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-2023-5958/ (Markdown: https://insights.sbomify.com/CVE-2023-5958/index.md)","id":"CVE-2023-5958","markdown":"https://insights.sbomify.com/CVE-2023-5958/index.md","name":"CVE-2023-5958","record":{"aliases":["GHSA-2r79-jc6j-hh65"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can inject malicious scripts via email content, potentially compromising highly privileged admin accounts in the POST SMTP Mailer plugin.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"post_smtp","vendor":"wpexperts"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The POST SMTP Mailer WordPress plugin before 2.7.1 does not escape email message content before displaying it in the backend, allowing an unauthenticated attacker to perform XSS attacks against highly privileged users.","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":"POST SMTP Mailer \u003c 2.7.1 - Unauthenticated Cross-site Scripting","id":"CVE-2023-5958","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Byzoro Smart S85F Management Platform login.php password recovery","id":"CVE-2023-5959"},"packages":[],"prev":{"headline":"Ni Purchase Order(PO) For WooCommerce \u003c= 1.2.1 - Admin+ File Upload to Remote Code Execution","id":"CVE-2023-5957"},"products":["POST SMTP Mailer"],"published":"2023-11-27","related":[{"cvss_score":9.8,"headline":"Auth bypass in Post SMTP – Complete Email Deliverability and SMTP Solution with Email Logs, Alerts, Backup SMTP \u0026 Mobile App","id":"CVE-2023-6875","kev_date_added":null,"published":"2024-01-11"},{"cvss_score":8.8,"headline":"POST SMTP Mailer \u003c 2.5.7 - Account Takeover via CSRF","id":"CVE-2023-3179","kev_date_added":null,"published":"2023-07-17"},{"cvss_score":8.6,"headline":"WordPress POST SMTP Mailer plugin \u003c= 2.8.6 - Broken Access Control on API vulnerability","id":"CVE-2023-52233","kev_date_added":null,"published":"2024-06-11"},{"cvss_score":7.6,"headline":"WordPress Post SMTP plugin \u003c= 2.9.9 - SQL Injection vulnerability","id":"CVE-2024-52436","kev_date_added":null,"published":"2024-11-18"},{"cvss_score":7.2,"headline":"Post SMTP \u003c= 3.0.2 - Unauthenticated Stored Cross-Site Scripting","id":"CVE-2025-0521","kev_date_added":null,"published":"2025-02-18"},{"cvss_score":7.2,"headline":"SQL injection in Post SMTP – Complete Email Deliverability and SMTP Solution with Email Logs, Alerts, Backup SMTP \u0026 Mobile App","id":"CVE-2024-5207","kev_date_added":null,"published":"2024-05-30"},{"cvss_score":7.2,"headline":"Post SMTP \u003c 2.8.7 - Admin+ SQL Injection","id":"CVE-2023-6620","kev_date_added":null,"published":"2024-01-15"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-02","vendors":["Unknown"]},"summary":"Unauthenticated attackers can inject malicious scripts via email content, potentially compromising highly privileged admin accounts in the POST SMTP Mailer plugin.","url":"https://insights.sbomify.com/CVE-2023-5958/"}
