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-2023-5561 exists.\n\nAffected packages and fixed versions:\n- wordpress (Bitnami): affected from 4.7.0; fixed in 4.7.27, 4.8.23, 4.9.24, 5.0.20, 5.1.17, 5.2.19, 5.3.16, 5.4.14, 5.5.13, 5.6.12, 5.7.10, 5.8.8, 5.9.8, 6.0.6, 6.1.4, 6.2.3, 6.3.2\n- wordpress-multisite (Bitnami): affected from 4.7.0; fixed in 4.7.27, 4.8.23, 4.9.24, 5.0.20, 5.1.17, 5.2.19, 5.3.16, 5.4.14, 5.5.13, 5.6.12, 5.7.10, 5.8.8, 5.9.8, 6.0.6, 6.1.4, 6.2.3, 6.3.2\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-2023-5561/ (Markdown: https://insights.sbomify.com/CVE-2023-5561/index.md)","id":"CVE-2023-5561","markdown":"https://insights.sbomify.com/CVE-2023-5561/index.md","name":"CVE-2023-5561","record":{"aliases":["BIT-wordpress-2023-5561","BIT-wordpress-multisite-2023-5561","DEBIAN-CVE-2023-5561","GHSA-x7w6-3cp2-qjcv","UBUNTU-CVE-2023-5561"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress CMS","requires_auth":"none","summary":"Unauthenticated attackers can disclose email addresses of users with public posts via REST API search flaws in WordPress.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"wordpress","vendor":"wordpress"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[],"description":"WordPress does not properly restrict which user fields are searchable via the REST API, allowing unauthenticated attackers to discern the email addresses of users who have published public posts on an affected website via an Oracle style attack","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":"2023-12-13","github_poc":3,"max_poc_stars":4,"metasploit":0,"nuclei":1,"refs":[{"date":"2023-12-13T16:43:18Z","kind":"github_poc","ref":"https://github.com/pog007/CVE-2023-5561-PoC","stars":4,"title":"WordPress does not properly restrict which user fields are searchable via the REST API, allowing unauthenticated attackers to discern the email addresses of users who have published public posts on an affected website via an Oracle style attack"},{"date":"2025-04-01T07:19:31Z","kind":"github_poc","ref":"https://github.com/rootxsushant/CVE-2023-5561-POC-Updated","stars":3,"title":"Updated POC for Unauth Post Author Email Disclosures WordPress CVE-2023-5561"},{"date":"2025-07-01T07:02:28Z","kind":"github_poc","ref":"https://github.com/dthkhang/CVE-2023-5561-PoC","stars":1,"title":"CVE-2023-5561-PoC"},{"date":null,"kind":"nuclei","ref":"http/cves/2023/CVE-2023-5561.yaml","stars":null,"title":"WordPress Core -
