Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-104723 in the wild and no public exploit code.\n\nAffected product: LifterLMS – WP LMS for eLearning, Online Courses, \u0026 Quizzes. 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-2026-104723/ (Markdown: https://insights.sbomify.com/CVE-2026-104723/index.md)","id":"CVE-2026-104723","markdown":"https://insights.sbomify.com/CVE-2026-104723/index.md","name":"CVE-2026-104723","record":{"aliases":["GHSA-5m5m-xm33-gpq9"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress LMS plugin","requires_auth":"low_privilege","summary":"Authenticated attackers can inject PHP objects via lesson data, potentially leading to code execution or data access if a POP chain exists.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"The LifterLMS – WP LMS for eLearning, Online Courses, \u0026 Quizzes plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 10.2.1 via deserialization of untrusted input . This makes it possible for authenticated attackers, with custom-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present. This vulnerability is only exploitable during lesson creation when a temporary lesson ID triggers the custom metadata path, and requires the attacker to hold a role with the edit_course capability, such as Instructor, Instructor's Assistant, LMS Manager, or Administrator.","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":"LifterLMS \u003c= 10.2.1 - Authenticated (Custom+) PHP Object Injection via 'custom' Lesson Data","id":"CVE-2026-104723","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":6,"next":{"headline":"FireBox \u003c= 3.1.13 - Authenticated (Author+) SQL Injection via FireBox Form Display Condition","id":"CVE-2026-104724"},"packages":[],"prev":{"headline":"Path traversal in Listdom: AI-powered Business Directory with Classifieds Ads Listings","id":"CVE-2026-104722"},"products":["LifterLMS – WP LMS for eLearning, Online Courses, \u0026 Quizzes"],"published":"2026-10-10","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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-11","vendors":["lifterlms"]},"summary":"Authenticated attackers can inject PHP objects via lesson data, potentially leading to code execution or data access if a POP chain exists.","url":"https://insights.sbomify.com/CVE-2026-104723/"}
