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-2023-40556 in the wild and no public exploit code.\n\nAffected product: Greg Ross Schedule Posts Calendar. 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-2023-40556/ (Markdown: https://insights.sbomify.com/CVE-2023-40556/index.md)","id":"CVE-2023-40556","markdown":"https://insights.sbomify.com/CVE-2023-40556/index.md","name":"CVE-2023-40556","record":{"aliases":["GHSA-4545-jvqf-cxg8"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"An attacker can trick authenticated users into performing unintended actions in the Schedule Posts Calendar plugin, potentially altering post schedules.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[{"product":"schedule_posts_calendar","vendor":"toolstack"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"Cross-Site Request Forgery (CSRF) vulnerability in Greg Ross Schedule Posts Calendar plugin \u003c= 5.2 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 Schedule Posts Calendar Plugin \u003c= 5.2 is vulnerable to Cross Site Request Forgery (CSRF)","id":"CVE-2023-40556","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"csrf","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"WordPress Tabs \u0026 Accordion plugin \u003c= 1.3.10 - Content Injection vulnerability","id":"CVE-2023-40557"},"packages":[],"prev":{"headline":"WordPress Flatsome Theme \u003c= 3.17.5 is vulnerable to PHP Object Injection","id":"CVE-2023-40555"},"products":["Schedule Posts Calendar"],"published":"2023-10-06","related":[{"cvss_score":5.9,"headline":"WordPress Schedule Posts Calendar Plugin \u003c= 5.2 is vulnerable to Cross Site Scripting (XSS)","id":"CVE-2023-40560","kev_date_added":null,"published":"2023-09-06"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-28","vendors":["Greg Ross"]},"summary":"An attacker can trick authenticated users into performing unintended actions in the Schedule Posts Calendar plugin, potentially altering post schedules.","url":"https://insights.sbomify.com/CVE-2023-40556/"}
