An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-0876 exists.\n\nAffected product: Unknown WP Meta SEO. 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-2023-0876/ (Markdown: https://insights.sbomify.com/CVE-2023-0876/index.md)","id":"CVE-2023-0876","markdown":"https://insights.sbomify.com/CVE-2023-0876/index.md","name":"CVE-2023-0876","record":{"aliases":["GHSA-hjvp-3h96-35mg"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Low-privilege users can exploit missing authorization in WP Meta SEO to modify data and trigger arbitrary redirects.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"wp_meta_seo","vendor":"joomunited"}],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[],"description":"The WP Meta SEO WordPress plugin before 4.5.3 does not authorize several ajax actions, allowing low-privilege users to make updates to certain data and leading to an arbitrary redirect vulnerability.","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/2023/CVE-2023-0876.yaml","stars":null,"title":"WordPress Meta SEO \u003c= 4.5.2 - Open Redirect"}],"tier":"weaponised"},"has_fix":null,"headline":"WP Meta SEO \u003c 4.5.3 - Subscriber+ Improper Authorization causing Arbitrary Redirect","id":"CVE-2023-0876","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Code Injection in froxlor/froxlor","id":"CVE-2023-0877"},"packages":[],"prev":{"headline":"WP Meta SEO \u003c 4.5.3 - Subscriber+ SQLi","id":"CVE-2023-0875"},"products":["WP Meta SEO"],"published":"2023-03-20","related":[{"cvss_score":8.8,"headline":"WP Meta SEO \u003c 4.5.5 - Author+ PHAR Deserialization","id":"CVE-2023-1381","kev_date_added":null,"published":"2023-04-10"},{"cvss_score":8.8,"headline":"WP Meta SEO \u003c 4.5.3 - Subscriber+ SQLi","id":"CVE-2023-0875","kev_date_added":null,"published":"2023-03-20"},{"cvss_score":7.2,"headline":"WP Meta SEO \u003c= 4.5.12 - Unauthenticated Stored Cross-Site Scripting via Referer header","id":"CVE-2023-6961","kev_date_added":null,"published":"2024-05-02"},{"cvss_score":6.5,"headline":"WordPress WP Meta SEO plugin \u003c= 4.5.13 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2024-45456","kev_date_added":null,"published":"2024-09-15"},{"cvss_score":5.9,"headline":"WordPress WP Meta SEO plugin \u003c= 4.5.13 - Cross Site Scripting (XSS) vulnerability","id":"CVE-2024-45455","kev_date_added":null,"published":"2024-09-15"},{"cvss_score":5.4,"headline":"WP Meta SEO \u003c= 4.5.3 - Missing Authorization in 'wpmsGGSaveInformation'","id":"CVE-2023-1022","kev_date_added":null,"published":"2023-02-28"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-26","vendors":["Unknown"]},"summary":"Low-privilege users can exploit missing authorization in WP Meta SEO to modify data and trigger arbitrary redirects.","url":"https://insights.sbomify.com/CVE-2023-0876/"}
