Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-104003 in the wild and no public exploit code.\n\nAffected product: properfraction Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile \u0026 Restrict Content – ProfilePress. 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-2026-104003/ (Markdown: https://insights.sbomify.com/CVE-2026-104003/index.md)","id":"CVE-2026-104003","markdown":"https://insights.sbomify.com/CVE-2026-104003/index.md","name":"CVE-2026-104003","record":{"aliases":["GHSA-6c6h-gv8v-jjr7"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated attackers can inject arbitrary shortcodes via comments, leading to server-side code execution and data exposure on user profile pages.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"The WP User Avatar / ProfilePress plugin for WordPress is vulnerable to Arbitrary Shortcode Execution in versions up to, and including, 4.17.5. This is due to the get_user_profile_structure() function assembling the front-end profile buffer — which includes raw comment excerpts inlined by author_comment_query() — and passing the entire buffer to do_shortcode() after only a narrow neutralization pass (ppress_neutralize_buffer_shortcodes) that blocks pp-custom-html and bracket fragments containing HTML delimiters but leaves any other well-formed shortcode intact. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary shortcodes (from any active plugin or theme) with attacker-chosen attributes by posting a comment whose body contains the shortcode markup; the shortcode is then executed server-side when any visitor loads the target's front-end profile Comments tab, letting the attacker reach capability-gated or data-returning shortcodes and inject raw HTML markup into a publicly viewable page.","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":"Code injection in Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile \u0026 Restrict Content – ProfilePress","id":"CVE-2026-104003","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":7,"next":{"headline":"Collection validators using collation-accepting expressions can crash MongoDB Server on insert","id":"CVE-2026-104004"},"packages":[],"prev":{"headline":"Fail-open error handling in the data masking utility in Powertools for AWS Lambda (Python)","id":"CVE-2026-104002"},"products":["Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile \u0026 Restrict Content – ProfilePress"],"published":"2026-10-16","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":"partial"},"state":"PUBLISHED","updated":"2026-10-16","vendors":["properfraction"]},"summary":"Authenticated attackers can inject arbitrary shortcodes via comments, leading to server-side code execution and data exposure on user profile pages.","url":"https://insights.sbomify.com/CVE-2026-104003/"}
