An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-24378 in the wild and no public exploit code.\n\nAffected product: Metagauss EventPrime. 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-2026-24378/ (Markdown: https://insights.sbomify.com/CVE-2026-24378/index.md)","id":"CVE-2026-24378","markdown":"https://insights.sbomify.com/CVE-2026-24378/index.md","name":"CVE-2026-24378","record":{"aliases":["GHSA-544w-wmqh-vq4j"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"An attacker can exploit PHP object injection in the EventPrime WordPress plugin to potentially execute arbitrary code.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Deserialization of Untrusted Data vulnerability in Metagauss EventPrime eventprime-event-calendar-management allows Object Injection.This issue affects EventPrime: from n/a through \u003c= 4.2.8.0.","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 EventPrime plugin \u003c= 4.2.8.0 - PHP Object Injection vulnerability","id":"CVE-2026-24378","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"WordPress WP Job Portal plugin \u003c= 2.4.3 - Insecure Direct Object References (IDOR) vulnerability","id":"CVE-2026-24379"},"packages":[],"prev":{"headline":"WordPress Nexter Blocks plugin \u003c= 4.6.3 - Sensitive Data Exposure vulnerability","id":"CVE-2026-24377"},"products":["EventPrime"],"published":"2026-03-25","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-28","vendors":["Metagauss"]},"summary":"An attacker can exploit PHP object injection in the EventPrime WordPress plugin to potentially execute arbitrary code.","url":"https://insights.sbomify.com/CVE-2026-24378/"}
