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-2022-4120 exists.\n\nAffected product: Unknown Stop Spammers Security | Block Spam Users, Comments, Forms. 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-2022-4120/ (Markdown: https://insights.sbomify.com/CVE-2022-4120/index.md)","id":"CVE-2022-4120","markdown":"https://insights.sbomify.com/CVE-2022-4120/index.md","name":"CVE-2022-4120","record":{"aliases":["GHSA-7x93-m29h-6j9q"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can achieve code execution via PHP object injection in the Stop Spammers Security WordPress plugin when CAPTCHA is enabled.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"stop_spammers","vendor":"trumani"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"The Stop Spammers Security | Block Spam Users, Comments, Forms WordPress plugin before 2022.6 passes base64 encoded user input to the unserialize() PHP function when CAPTCHA are used as second challenge, which could lead to PHP Object injection if a plugin installed on the blog has a suitable gadget chain","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Stop Spammers Security \u003c 2022.6 - Unauthenticated PHP Object Injection","id":"CVE-2022-4120","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Null dereference in libetpan","id":"CVE-2022-4121"},"packages":[],"prev":{"headline":"Image Optimizer, Resizer and CDN \u003c 6.8.1 - Admin+ Stored XSS","id":"CVE-2022-4119"},"products":["Stop Spammers Security | Block Spam Users, Comments, Forms"],"published":"2022-12-26","related":[{"cvss_score":6.1,"headline":"Stop Spammers Security \u003c 2023 - Reflected XSS","id":"CVE-2023-2488","kev_date_added":null,"published":"2023-06-05"},{"cvss_score":6.1,"headline":"Stop Spammers \u003c 2021.9 - Reflected Cross-Site Scripting (XSS)","id":"CVE-2021-24245","kev_date_added":null,"published":"2021-05-05"},{"cvss_score":5.4,"headline":"Stop Spammers Security \u003c 2021.18 - Authenticated Stored XSS","id":"CVE-2021-24517","kev_date_added":null,"published":"2021-09-06"},{"cvss_score":4.8,"headline":"Stop Spammers Security \u003c 2023 - Admin+ Stored XSS","id":"CVE-2023-2489","kev_date_added":null,"published":"2023-06-05"}],"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)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-14","vendors":["Unknown"]},"summary":"Unauthenticated attackers can achieve code execution via PHP object injection in the Stop Spammers Security WordPress plugin when CAPTCHA is enabled.","url":"https://insights.sbomify.com/CVE-2022-4120/"}
